What to Know: U.S. Travel Restrictions

Beginning today, international visitors who are fully vaccinated against the coronavirus can enter the United States by air or across the land borders with Canada and Mexico.

Here’s the latest →

The new policy ends an 18-month ban on nonessential travel from 33 countries, including China, Brazil and European Union members. The ban had affected tourists and those hoping to visit family and friends in the U.S.

The rules reorient the U.S. approach to vetting its visitors during the pandemic.

Instead of basing entry decisions on travelers’ countries of origin, the U.S. is focusing on vaccination status.

International visitors flying into the U.S. now need to show proof of vaccination before boarding and a negative coronavirus test taken within three days of their flight.

The three vaccines available in the U.S. — Pfizer-BioNTech, Moderna and Johnson & Johnson — are accepted, as are vaccines cleared for emergency use by the W.H.O., including AstraZeneca and Covaxin.

Unvaccinated foreign visitors cannot enter the country, with limited exemptions.

Unvaccinated Americans returning home need to test negative for the coronavirus within one day of their flight and show proof they have purchased another test to take after arriving.

The hope is with these longstanding bans being lifted, the U.S. tourism industry will start to recover. The halt on travel caused a loss of nearly $300 billion in visitor spending, according to the U.S. Travel Association.

Places the U.S. Government Warns Not to Travel Right Now

You may want to reconsider traveling to these countries right now.

Do Not Travel to These Countries

Crime, civil unrest and terrorism are common risk factors for countries that end up on the State Department's "Do Not Travel" advisory list.

In 2024, tourism across the globe is “well on track” to return to pre-pandemic levels, according to projections by UN Tourism.

Global conflicts and natural disasters , ranging from a series of coups across Africa to catastrophic earthquakes in the Middle East affected international travel patterns throughout 2023. Still, international tourist arrivals reached 87% of pre-pandemic levels in 2023, according to estimates by UN Tourism .

In January 2024 alone, about 4.6 million U.S. citizens left the country for international destinations, 17% higher than the same month in 2019, according to the International Trade Administration . But some destinations warrant more caution than others.

On Oct. 19, 2023, following the outbreak of war between Israel and Gaza and flaring tensions in the region, the U.S. State Department issued a worldwide caution advisory due to “increased tensions in various locations around the world, the potential for terrorist attacks, demonstrations or violent actions against U.S. citizens and interests.” Prior to this update, the most recent worldwide caution advisory was issued in 2022 after a U.S. strike killed Ayman al-Zawahiri, Osama bin Laden’s successor as leader of Al Qaeda, causing “a higher potential for anti-American violence.” The worldwide caution advisory remains in effect.

The U.S. State Department also issues individual travel advisory levels for more than 200 countries globally, continually updating them based on a variety of risk indicators such as health, terrorism and civil unrest. Travel advisory levels range from Level 1, which means exercise normal precautions, to Level 4, which means do not travel there.

About 10% of countries – 19 total – have a Level 4: “Do Not Travel” advisory as of Mar. 4. In Level 4 countries, the U.S. government may have “very limited ability” to step in should travelers’ safety or security be at risk, according to the State Department. Crime, civil unrest, kidnapping and terrorism are common risk factors associated with Level 4 countries.

So far in 2024, the State Department made changes to the existing Level 4 advisories for Myanmar, Iran and Gaza, and moved Niger and Lebanon off of the Level 4 list.

Places With a Level 4 Travel Advisory

These are the primary areas the U.S. government says not to travel to right now, in alphabetical order:

Jump to Place: Afghanistan Belarus Burkina Faso Central African Republic Myanmar (formerly Burma) Gaza Haiti Iran Iraq Libya Mali Mexico North Korea (Democratic People's Republic of Korea) Russia Somalia South Sudan Sudan Syria Ukraine Venezuela Yemen

Afghanistan: The Central Asian country is wrestling with “terrorism, risk of wrongful detention, kidnapping and crime,” according to the State Department. U.S. citizens are specifically at risk for wrongful detention and kidnapping. In 2022, the government reinstituted public floggings and executions, and women’s rights are disappearing under Taliban control. The U.S. Embassy in Kabul halted operations in August 2021. Since the Taliban took control , many forms of international aid have been halted . Meanwhile, in 2023, some of the year’s deadliest earthquakes killed more than 2,400 in Afghanistan while the country continues to face a years-long extreme drought.

Belarus: Belarus, which shares a western border with Russia and a southern border with Ukraine, has been flagged for “Belarusian authorities’ continued facilitation of Russia’s war against Ukraine, the buildup of Russian military forces in Belarus, the arbitrary enforcement of local laws, the potential of civil unrest, the risk of detention, and the Embassy’s limited ability to assist U.S. citizens residing in or traveling to Belarus.” The U.S. Embassy in Minsk halted operations in February 2022.

Burkina Faso: Terrorism, crime and kidnapping are plaguing this West African nation. Terrorist attacks may target hotels, restaurants and schools with little to no warning, and the East and Sahel regions of the country are under a state of emergency. In late November 2023, hundreds died in clashes between state security forces and rebels near the country’s border with Mali. In June, more than 2 million people in Burkina Faso were displaced due to “violence linked to al-Qaida and the Islamic State group.”

Central African Republic: While there have not been specific incidents of U.S. citizens targeted with violence or crime, violent crime and sudden closure of roads and borders is common. The advisory states that “Embassy Bangui’s limited capacity to provide support to U.S. citizens, crime, civil unrest, and kidnapping” is a factor in its assessment. Recent data from UNICEF suggests the country has the worst drinking water accessibility of all countries in 2022.

Myanmar (Formerly Burma): Armed conflict and civil unrest are the primary reasons to not travel to this Southeast Asian country, which experienced a military coup in early 2021. Limited health care resources, wrongful detentions and “areas with land mines and unexploded ordnance” are also listed as risk factors. After Ukraine and Israel, Myanmar had the highest conflict-related death toll in 2023.

Gaza : Hamas, a foreign terrorist organization as designated by the State Department, controls much of the Gaza Strip, which shares borders with both Israel and Egypt. On Oct. 7, 2023, Hamas fighters broke across the border into Israel, killing hundreds of civilians and soldiers in a brazen attack that stunned Israelis. On Oct. 10, Israel hit the Gaza Strip with “the fiercest air strikes in its 75-year conflict” according to Reuters . The conflict has since escalated into war between Israel and Hamas, with regular Israeli airstrikes leading to extensive civilian casualties in Gaza. As of mid-December, nearly 85% of Gaza’s population were displaced from their homes, according to UN estimates . The region continues to face shortages of food , water, electricity and medical supplies , with conditions deemed “far beyond a humanitarian crisis.” The State Department warns of terrorism and armed conflict within Gaza’s borders.

Haiti: In July 2023, the Department of State ordered all non-emergency U.S. government personnel and family members to leave the U.S. Embassy in Port-au-Prince in response to the increased risk of kidnapping and violent crime in the country , as well as armed conflict between gangs and police. The travel advisory states that cases of kidnapping “often involve ransom negotiations and U.S. citizen victims have been physically harmed during kidnappings.” The travel advisory also states that “U.S. citizens in Haiti should depart Haiti as soon as possible” given “the current security situation and infrastructure challenges.” A series of gang attacks in late September 2023 caused thousands to flee their homes, and many aid groups have been forced to cut or suspend operations amid escalating violence in recent months.

Iran: Terrorism, kidnapping and civil unrest are risk factors for all travelers to Iran, while U.S. citizens are specifically at risk for “arbitrary arrest.” U.S.-Iranian nationals such as students, journalists and business travelers have been arrested on charges of espionage and threatening national security. Executions in Iran rose sharply between 2021 and 2022, bringing the country’s total to nearly 580 people over the year, according to a report by Amnesty International released in May 2023.

Iraq: The State Department cites “terrorism, kidnapping, armed conflict [and] civil unrest” as cause for the country’s Level 4 distinction. Iraq’s northern borders, and its border with Syria, are especially dangerous. Since the escalation of conflict in neighboring Israel in October, there has been an increase in attacks against Iraqi military bases, which host U.S. troops and other international forces. In October 2023, non-emergency U.S. government personnel and eligible family members were ordered to leave the U.S. embassy in Baghdad.

Libya: Following the end of its dictatorship over a decade ago, Libya has been wrought with internal conflict between armed groups in the East and West. Armed conflict, civil unrest, crime, kidnapping and terrorism are all risk factors. U.S. citizens have been targets of kidnapping for ransom, with terrorists targeting hotels and airports frequented by Westerners. The U.S. Embassy in Tripoli halted operations in 2014. In mid-September 2023, floods, which some say were intensified by climate change , killed thousands in eastern Libya. Clashes between armed factions escalated across the country in the latter half of 2023, including in the capital city of Tripoli and in Benghazi.

Mali: After experiencing military coups in 2020 and 2021, crime, terrorism and kidnapping are all prevalent threats in this West African landlocked nation. In July 2022, non-emergency U.S. government employees and their families were ordered to leave the country due to higher risk of terrorist activity. A U.N. report in August 2023 said that military groups in the country, including both Mali security forces and possibly Russian Wagner mercenaries, were spreading terror through the use of violence against women and human rights abuses. Democratic elections were supposed to occur in February 2024, but Mali’s military junta postponed the plans indefinitely. In December, the U.N. officially ended a decade-long peacekeeping presence in the country, which had been among the agency’s deadliest missions, with hundreds of the mission personnel killed since 2013.

Mexico: Each state in Mexico is assessed separately for travel advisory levels. Six of the 32 states in Mexico are designated as Level 4: Colima, Guerrero, Michoacan, Sinaloa, Tamaulipas and Zacatecas. Crime and kidnapping are listed as the primary risk factors throughout the country. Nearly 112,000 people were missing across the country as of October, a number the U.N. has called “alarming.”

North Korea (Democratic People’s Republic of Korea): U.S. passports are not valid for travel “to, in, or through” this country, home to one of the world's longest-running dynastic dictatorships. The travel advisory states that the Level 4 distinction is due to “the continuing serious risk of arrest and long-term detention of U.S. nationals.” In July 2023, a U.S. soldier fled across the border into North Korea, where he is believed to be in North Korean custody, the first American detained in the North in nearly five years. He was returned to U.S. custody in September 2023.

Russia: The travel advisory for Russia cites its invasion of Ukraine , harassment of U.S. citizens by Russian government officials and arbitrary law enforcement as a few of the reasons for the Level 4 designation. Chechnya and Mount Elbrus are specifically listed as Level 4 regions. Terrorism, civil unrest, health, kidnapping and wrongful detention are all noted as risks.

Russia Invades Ukraine: A Timeline

Somalia: A severe drought resulting from five failed rainy seasons in a row killed 43,000 people in 2022, and caused a famine amid conflict with Islamist insurgents . Violent crime is common throughout Somalia , pirates frequent its coast off the Horn of Africa, and medical facilities, where they exist, have limited capacity. Crime, terrorism, civil unrest, health and kidnapping are all risk factors. In January 2024, some passengers aboard a U.N.-contracted helicopter were taken hostage by al-Shabaab militants after the vehicle crashed in central Somalia.

South Sudan: Crime, kidnapping and armed conflict are the primary risk factors for South Sudan, which separated from Sudan in 2011, making it the world’s newest country . Weapons are readily available, and travelers have been victims of sexual assault and armed robbery.

Sudan: The U.S. evacuated its embassy in Khartoum in April 2023, and the country closed its airspace due to the ongoing conflict in the country, only permitting humanitarian aid and evacuation efforts. Fighting has escalated in the region between two warring generals seeking to gain control after a military coup in 2021 ousted the country’s prime minister. Civil unrest is the primary risk factor for Africa’s third largest country by area. Crime, terrorism, kidnapping and armed conflict are also noted. The International Criminal Court began investigating alleged war crimes and violence against African ethnic groups in the country in 2023. Millions have fled their homes due to conflict, and the U.N. has said its efforts to provide aid have been hindered by a lack of support, safety and resources. As recently as December 2023, the United Nations warned of catastrophic famine , with millions of children at-risk for malnutrition .

Syria: The advisory states that “No part of Syria is safe from violence,” with terrorism, civil unrest, kidnapping, armed conflict and risk of unjust detention all potential risk factors. U.S. citizens are often a target for kidnappings and detention. The U.S. Embassy in Damascus halted operations in 2012. Fighting in neighboring Israel has escalated since October, and the conflict has spilled over into Syria, where the U.S. has carried out air strikes following drone and rocket attacks against American troops in Syria and Iraq, triggered by the Israel-Hamas war.

Ukraine: Russian setbacks in their invasion of Ukraine buoyed hopes in Ukraine in 2023. However, Ukraine is a Level 4 country due to Russia’s invasion, with crime and civil unrest also noted as risk factors. The country’s forces shot down two Russian fighter jets on Christmas Eve 2023, in a move Ukrainian President Volodymyr Zelenskyy said “sets the right mood for the entire year ahead.”

Venezuela: Human rights abuses and lack of health care plague this South American nation, which has been in a political crisis since 2014. In 2019, diplomatic personnel were withdrawn from the U.S. Embassy in Caracas. Threats in the country include crime, civil unrest, kidnapping, wrongful detention and poor health infrastructure.

Yemen: Six of the nine risk factors defined by the State Department – terrorism, civil unrest, health risks, kidnapping, armed conflict and landmines – are all present in Yemen. Despite private companies offering tourist visits to the Yemeni island of Socotra, the U.S. government argues those arranging such visits “are putting tourists in danger.” Civil war and cholera are also both present throughout the country. The U.S. Embassy in Sanaa halted operations in 2015. The country has experienced a relative lull in the civil war fighting, but as peace negotiations have gotten traction, flare ups in the fighting have jeopardized progress. Most recently, the U.S. and U.K. have carried out a series of airstrikes in the country, targeting Iran-backed Houthi sites.

Other Countries to Watch

Since Jan. 1, the State Department has updated travel advisories for 17 different countries as well as for the West Bank and Gaza, adding information about specific regions or risk factors, or simply renewing an existing advisory. Travel advisory levels can change based on several factors in a nation, such as increased civil unrest, policies that affect human rights or higher risks of unlawful detention.

The State Department has given about 25 countries an assessment of Level 3, meaning it recommends people “reconsider travel” to those destinations.

On Oct. 14, one week after the deadly Hamas attack on Israel, Israel and the West Bank were both moved from Level 2 to Level 3, while Gaza remains at Level 4. The region’s travel advisory was updated in November to reflect travel restrictions for certain government employees who have not already left the area, and it was updated again on Jan. 3.

Following the outbreak of the Israel-Hamas war in early October, the U.S. State Department raised Lebanon ’s travel advisory level from a Level 3 to a Level 4 level due to “the unpredictable security situation related to rocket, missile, and artillery exchanges” between Israel and Hezbollah or other militant groups. In December, the U.S. Embassy in Beirut returned to normal staffing and presence, and on Jan. 29, the country was moved back to Level 3. Crime, terrorism, armed conflict, civil unrest, kidnapping and unexploded landmines are listed as the country’s primary risk factors. However, the country’s borders with Syria and with Israel, as well as refugee settlements within Lebanon, are specifically noted as Level 4 regions.

China became a Level 3 country in late 2020, with an update in December 2022 citing “the surge in COVID-19 cases, arbitrary enforcement of local laws, and COVID-19-related restrictions” as the reason for the advisory. In June 2023, the Hong Kong Special Administrative Region (SAR) was moved from the Level 3 to the Level 2 list, but travelers are still advised to be cautious in the area due to “arbitrary enforcement of local laws.” Meanwhile, Macau remains at Level 3.

Following an attempted coup in August 2023, Niger was elevated to Level 4 in August and the Department of State ordered all non-emergency U.S. government personnel and family members to leave the U.S. Embassy in Niamey. In early January 2024, the overall risk level for the country was lowered back to Level 3. Despite the new classification, the State Department still asks non-emergency government personnel and eligible family members to depart the country.

In mid-December 2023 there was an explosion at Guinea’s main fuel depot which has since affected access to health care and basic goods and services. The country was subsequently designated a Level 3 nation after having previously been Level 2. Concerns about civil unrest, health, crime and fuel shortages impacting local infrastructure were listed as the primary risk factors contributing to the change.

Several Level 3 countries are among the worst countries for human trafficking, as designated by the State Department’s annual Trafficking in Persons Report . Level 3 countries on this list include Papua New Guinea, Guinea Bissau, China and Chad. There are also nine Level 4 countries designated as among the worst for human trafficking: Afghanistan, Belarus, Iran, Myanmar, North Korea, Russia, Syria, South Sudan and Venezuela.

Over 70 countries are currently at Level 2, meaning the State Department recommends travelers “exercise increased caution” when traveling to those destinations.

Botswana became the newest Level 2 country on Feb. 26 after having previously been Level 1, with crime noted as the primary risk factor.

France, which saw nationwide protests throughout 2023, has civil unrest and terrorism noted as risk factors for its Level 2 status, and Sweden’s Level 2 status is associated with risks of terrorism.

The Level 2 travel advisory for the Bahamas was updated in January to reflect water safety concerns. The advisory warns that “activities involving commercial recreational watercraft, including water tours, are not consistently regulated” and notes that government personnel are “not permitted to use independently operated jet-ski rentals on New Providence and Paradise Islands.” It also warns visitors to be mindful of sharks, weather and water conditions. The advisory also says that crime is a primary risk factor with gang-on-gang violence contributing to high homicide rates in some areas. Visitors are asked to “be vigilant” and to not physically resist robbery attempts.

Bangladesh 's Level 2 travel advisory was updated in October 2023 to add a note about the country’s general election , which took place Jan. 7, 2024. The advisory states “demonstrations intended to be peaceful can turn confrontational and escalate into violence.” The U.S. has since claimed the country’s election was not free nor fair.

In November 2023, several Level 2 travel advisories were updated with new cautionary information. The advisory for Ghana was updated to reflect threats against LGBTQI+ travelers specifically, noting “anti-LGBTQI+ rhetoric and violence have increased in recent years.” Meanwhile, the advisory for South Africa was updated in February to note that routes recommended by GPS may be unsafe with higher risk for crime.

Turkmenistan was moved off of the Level 2 list to become the newest addition to the Level 1 list on Jan. 22, meaning normal precautions are recommended but there are no risk factors causing travelers to practice increased caution.

The State Department asks travelers to pay attention to travel advisory levels and alerts , review country information pages for their destinations and read related country security reports before going abroad.

Is it safe to go there? The U.S. travel advisory system, explained

If you’re planning an international trip, here’s how to use the State Department’s country-by-country guide to minimize your risk of encountering crime, violence, or civil unrest.

On October 19, the U.S. Department of State issued a rare advisory that Americans overseas “exercise increased caution” due to heightened tensions and chances of terrorism around the world, spurred by the Israel-Hamas war. It’s part of a system of travel warnings that’s been around in some form since 1978, designed to help citizens assess how safe a destination might be at a given time.

The current version of the system, which launched in 2018, gives fluid rankings from Level 1 (exercise normal precautions) to Level 4 (do not travel), indicating how risky countries (and in some cases, regions) are for Americans to visit. Rankings are based on factors such as crime rates, civil unrest, and the threat of terrorism. They are meant to give “clear, timely, and reliable information about every country in the world so they can make informed travel decisions,” says a State Department spokesperson.  

Not surprisingly, on October 14, the State Department moved Israel and the West Bank to Level 3 (reconsider travel) and Gaza to Level 4.  

Here’s how the advisories work and how to use them.

What is a travel advisory?

The U.S. State Department inaugurated the travel advisory system in 1978, initially aiming warnings at airlines and travel companies. The system was scrutinized after the 1988 bombing of a Pan Am flight from London to New York , which exploded over Lockerbie, Scotland , killing all 259 passengers and crew plus 11 people on the ground.  

Investigations found U.S. authorities had been aware of a credible threat to a Pan Am flight but hadn’t informed the public. In response, the media and consular offices began issuing travel warnings. In 2018 the U.S. introduced its current four-tier advisory system. There are near-identical versions in Canada , Australia , and New Zealand .

To determine rankings, the State Department considers a nation’s political volatility, crime trends, medical care standards, and the threat of kidnappings or terrorism. (Politics also ends up playing an unspoken role.) Some countries, such as Russia , receive a Level 4 ranking partly because the U.S. government may have limited ability to assist citizens there. Others rise to Level 4 due to a crisis, such as the military coup that recently rocked Niger .  

When the travel advisory system relaunched in 2018, it also included state-by-state evaluations for Mexico , which draws more than 11 million American travelers a year. “Some Mexican states are quite safe for U.S. tourists, while others are riskier due to narco-trafficking violence,” says Ryan Larsen , executive director of the Institute for Global Engagement at Western Washington University. Yucatán and Campeche states are currently at Level 1, while six other Mexican states are at Level 4, including Sinaloa.

Epidemics and natural disasters also can prompt a travel advisory number to rise. Americans may be prompted to reconsider visiting a country recovering from a tsunami or major wildfires, since their presence could hinder rehabilitation efforts. This occurred after the February 2023 earthquakes in Turkey . Such advisories can remain in place for weeks or months.

The strictest-ever advisories came in April 2021, amid the COVID-19 pandemic , says Larsen, who did a thesis   on U.S. travel warnings. At that time, about 80 percent of the world’s countries were at Level 4.

At press time, about 70 percent of the world’s countries were rated Level 1 or Level 2 by the State Department, indicating they’re relatively safe. There are currently 21 countries at Level 3 and 21 at Level 4.

How to use travel advisories

Before booking an international trip, consult the State Department website to see where your destination ranks. While Level 1 and 2 countries are considered relatively safe, you should still register with the U.S. Smart Traveler Enrollment Program (STEP) . This lets Americans overseas use their smartphone to receive travel advisory updates and alerts about emerging dangers in their destination (protests, extreme weather).

Level 3 countries are considered more dangerous for foreign visitors, who should “reconsider travel,” according to the State Department. If you are headed to a Level 3 country, which currently includes Pakistan and Colombia , do wider research on its safety and on the places you’ll visit there, advises Jun Wen , a professor of tourism at Australia’s Edith Cowan University. For instance, while some remote areas in the Colombian Amazon still suffer from drug-related violence, cities such as Cartagena and Medellín are relatively safe. Going on a fully guided group or individual tour can also help you navigate destinations where political unrest or crime might impact your safety.

Travelers should study not only the advisories provided by their own country, but also by the U.S., United Kingdom, and Australia to broaden their understanding of the risks in Level 3 countries, Wen says. As for Level 4 countries, that “Do Not Travel” advice couldn’t be any clearer.

Other countries also issue warnings to their citizens about visiting the U.S. Canada recently informed its LGBTQ travelers they may be affected by laws in certain U.S. states. Australia, meanwhile, cautions its citizens visiting the U.S. to be wary of higher crime rates and gun violence, and even to learn safety strategies for active shooter scenarios.

People who visit countries with Level 3 or Level 4 travel advisories don’t just risk their safety. They also may have travel insurance complications, says Linchi Kwok , tourism management professor at California State Polytechnic University Pomona.

( How travel insurance can—and can’t—help when your plans change .)

They must pay much higher premiums, and their insurance can be invalidated if the advisory for their destination is elevated. “Medical coverage can be minimal, too, particularly if the travel advisory is put up against a disease or an outbreak,” says Kwok. “I encourage Americans to think twice before they travel to Level 3 and especially Level 4 destinations.”

Warnings and their impact on tourism

Travel advisories can be biased, Larsen argues. His research found that, while the U.S. didn’t often overstate the risk of travel to countries with which it had poor relations, it did often understate the danger of visiting nations that were its close allies. Elevating a travel advisory can stoke diplomatic tensions between two countries. Once a country is raised to Level 3 or 4, many tourists will avoid visiting, and many American universities won’t let students join study abroad programs.

The economic ramifications of a level change impact individual businesses such as hotels, restaurants, and travel agencies. For instance, J 2   adventures , a Jewish-focused tour company, saw most of its fall group trips to Israel canceled after the start of the Israel-Hamas war (and the higher advisory level), says cofounder Guy Millo. “This is not just because of the violence on the ground, but because of practical considerations like accessibility of commercial airline flights,” he says. “Most tourists from North America and places around the globe simply couldn’t get here even if they wanted to.”

Everything you need to know about State Department travel advisories

When traveling abroad, the top concern for many Americans is safety.

Whether it is due to ongoing conflict, special events such as the 2024 Paris Olympics , natural disasters like a volcano currently erupting in Iceland or an uptick in crime , conditions of countries can change rapidly, affecting both travelers and locals.

To help keep American travelers safe, the U.S. Department of State issues and maintains travel advisories for U.S. citizens based on current circumstances.

These advisories can be particularly helpful for first-time and younger travelers, though the agency encourages all people to review them for their desired destination ahead of travel.

What are travel advisories based on?

Although travel warnings originate from the State Department and live on its website , they are a joint effort between the State Department's Office of Overseas Citizens Services and U.S. consulates and embassies worldwide.

"We've got our diplomats and consular officers on the ground in all those places, who have more up-to-date information than anyone in Washington could have," said Angela Kerwin, deputy assistant secretary for Overseas Citizens Services, during a Zoom interview Thursday. "But we use a variety of information in order to look at the criteria that go into our travel advisories around the world."

In addition to crime reports, nongovernmental organization reports and those from international organizations such as the United Nations, the government considers nine risk factors in determining the level at which each country's advisory should be set:

• C — Crime : Widespread violence or organized crime is present in areas of the country. Local law enforcement may have limited ability to respond to serious crimes.
• T — Terrorism : Terrorist attacks have occurred and/or specific threats against civilians, groups or other targets may exist.
• U — Civil Unrest : Political, economic, religious and/or ethnic instability exists and may cause violence, major disruptions and/or safety risks.
• H — Health : Health risks, including current disease outbreaks or a crisis that disrupts a country's medical infrastructure. The issuance of a Centers for Disease Control and Prevention Travel Health Notice may also be a factor.
• N — Natural Disaster : A natural disaster, or its aftermath, poses danger.
• E — Time-limited Event : Short-term events, such as elections, sporting events or other incidents that may pose safety risks.
• K — Kidnapping or Hostage Taking : Criminal or terrorist individuals or groups have threatened to and/or have seized or detained and threatened to kill, injure or continue to detain individuals in order to compel a third party (including a governmental organization) to do or abstain from doing something as a condition of release.
• D — Wrongful Detention : The risk of wrongful detention of U.S. nationals exists.
• O — Other : Potential risks are not covered by previous risk indicators. Read the country's travel advisory for details.

Although the most recently added category, Wrongful Detention, only applies to a handful of countries, it's an important criterion for travelers to note when a country has detained a U.S. citizen without cause.

Level 1 to 4 tiered warning system

Based on that nine-rubric system, plus reports and input from U.S. consulates and embassies in these countries, the agency assigns each country a Level 1 to 4 tiered warning , with 1 being the lowest level, indicating relative safety, and 4 being the highest, meaning travelers should not visit.

Level 1: Exercise normal precautions

This is the lowest level a country can achieve, making it among the safest for Americans to visit. As with any travel, there is always some risk, so every country will always have at least a Level 1 advisory.

Level 2: Exercise increased caution

Under a Level 2 designation, a country has increased safety or security risks, but they likely won't preclude you from traveling there.

Level 3: Reconsider travel

A Level 3 advisory tells travelers to potentially defer trips to the country in question, as serious potential risks exist.

Level 4: Do not travel

The most serious advisories are Level 4 recommendations, which alert you to avoid travel to designated countries and areas due to a greater threat of potentially life-threatening risks and limited resources to help Americans.

What else to know about travel advisories

In addition to the State Department's general travel advisory, a country's information page will also provide any timely alerts from the corresponding U.S. embassy and/or consulate to consider.

There are also certain countries where the agency can provide "carve-outs" to communicate information related to specific areas or regions within a particular country.

"Perhaps the country itself is a Level 3 country, but there is one particular border area that has ongoing kinetic activity of some sort, and we'd say that would be a Level 4," Kerwin explained.

These carve-outs are most often found in Mexico , as the U.S. shares a border with the country and more Americans travel to Mexico for tourism than elsewhere.

"Mexico is a special case. We also have more U.S. consulates than we do in any other country in the world, and for that reason, we are able to provide state-by-state travel advisory levels in Mexico," Kerwin said. "[With] other countries around the world, [we] just simply don't have the ability to have that level of detail; the specificity is greater for Mexico."

Because data is the main source of information for crafting these advisories, not all alerts can be created equally.

"It is impossible to say that we can apply all nine criteria exactly the same in country A as we do in country B. You're going to have more statistical data of a reliable type for ... Germany than you would Chad," Kerwin explained. "So to compare the exact same report for Germany with the exact same report for Chad is not something that makes sense because it's generally not going to be available."

In those cases, the government relies on its embassies and consulates, which are present in most of these countries, to help inform its alerts.

"We've got people on the ground who are often best positioned to help us evaluate the number of kidnappings, the level of civil unrest, how many terrorist attacks reported or not reported," she said.

Note that a lack of readily available or accurate data doesn't make the country inherently riskier or more dangerous for travelers.

"It just means that we don't have the exact type of data that we would have in another country," Kerwin said. "We would have to rely more heavily on embassy reporting and our folks there, but it does not necessarily mean it is a more dangerous country."

Does a Level 4 alert mean I should avoid traveling there?

In short, the answer is yes.

At the time of publication, there were 19 countries with Level 4 alerts, per the State Department.

"These are the places we deem as the most dangerous for U.S. citizens to travel to, and we would really like U.S. citizens to look at other destinations," Kerwin said. In part, that's because of the limited consular or embassy services available in these places should an American need help.

"Every U.S. citizen gets to make up their own mind on where they want to travel. That's all we can do as a government," she continued. "If a U.S. citizen finds themselves in a situation where they need to travel to one of these countries for whatever reason, we would ask that they look at our travel advisories in advance, read our country information sheet. We would certainly recommend if we have a functioning embassy, that they save that information on their phone so they can contact the embassy if necessary."

But overall, travelers should avoid traveling to Level 4 countries if possible.

"Each of these Level 4 countries will tell you what our concerns are with these countries and [that] our criteria has been met," Kerwin said. "We believe it is quite dangerous to go there."

How often are State Department travel advisories updated?

When viewing a travel advisory, you'll note at the top the date it was last updated, as alerts are updated on a rolling basis.

Generally speaking, Level 4 and Level 3 alerts are updated at least once every six months, while Level 1 and Level 2 alerts are examined at least once per year, pending evolving circumstances.

"If something changes or some precipitating event, we would do it earlier as needed," Kerwin said.

For example, on Thursday, the U.S. Embassy in Reykjavik issued its own alert regarding a volcanic eruption in southwest Iceland that morning. When embassy alerts are issued for isolated events in a particular region of a country, it does not necessarily reflect the overall level of the country as a whole.

Despite the volcano warning, Iceland remained at Level 1 , as it has since July. If it had been a more widespread eruption affecting general European air travel, that would have prompted the agency to update the travel advisory as a whole.

"Right now, by sending out that security alert, we're saying stay away from the volcano, but if you wanna go have dinner in Reykjavik, follow our regular information we have on our travel advisory," Kerwin said.

That volcano alert also went out via the agency's Smart Traveler Enrollment Program , which sends relevant security updates from the nearest U.S. Consulate, and which Kerwin advised travelers to enroll in as another way to stay safe abroad.

"So anybody who is registered in STEP traveling to or who is living in Iceland would've gotten an email to say, 'Hey, be aware the volcano erupted again today, we're watching it closely; pay attention,'" she explained. "We have those various security alerts that we can send out at any time in a country based on late-breaking events."

Special events, such as the upcoming 2024 Paris Olympics, will also trigger additional and/or more frequent alerts.

"We will be paying special attention to that. We expect there will be a large number of U.S. citizens that are headed in that direction to cheer on our team, and we want to make sure that we are giving them the best information we can about their time when they're traveling," Kerwin said.

Other things to consider when traveling abroad

As with travel in general, the State Department advises Americans heading overseas to prepare in advance.

"We have a slogan we've been using, and I like it; it's called 'travel smart from the start,' and that starts even before you decide what destination," Kerwin said. That slogan applies to details like checking that you have enough validity on your passport (most countries require six months at the time of entry) and buying travel insurance.

Kerwin also advises procuring the contact information for the nearest U.S. government presence (i.e., the embassy or consulate) via the State Department's list of U.S. embassies and consulates .

"Jot down on paper, take a picture on your phone and save the U.S. Embassy/Consulate phone number or email address so you can get in contact with us if there's a problem," she said. "And always be aware of your surroundings ... a heightened level of awareness ... is important for travelers no matter where they're going."

Bottom line

With travel comes an inherent risk, and the government aims to help travelers remain safe domestically and abroad.

While the decision to travel is ultimately up to the traveler, these travel advisories should be taken seriously.

"Our goal is to always provide the best advice and information we can for U.S. citizens so they can make their decisions as to where they wish they travel," Kerwin said.

Therefore, heed these travel warnings from the State Department via U.S. embassies, consulates and the department's STEP program.

"The final thing — and this is an important one — is to have fun," Kerwin added. "Travel is fantastic — you get to see new cultures, and you get to experience new languages and beautiful countries and beautiful cities. We want U.S. citizens to travel and have fun on their adventures around the world."

Verywell's Interactive Map Can Help You Plan Your Holiday Travel

Verywell / Jessica Olah

Key Takeaways:

• Americans are planning to travel this holiday season.
• Use our interactive map to check local COVID-19 case numbers, vaccination rates, mask mandates, and other key data points by state.
• There are other factors like masking and boosters you should take into consideration before you travel.

This year marks our second holiday season amidst a global pandemic. Navigating high COVID-19 cases and tough conversations about vaccines among families may be giving some people pause in traveling for the holidays. 

In Verywell Health's latest vaccine sentiment survey, we asked survey respondents in early November about their plans this year. Most Americans—62%—are planning to visit with friends or family outside of their household during the upcoming holidays.

And almost a third (30%) are planning to travel away from home. But not everyone is throwing caution to the wind—29% are at least somewhat concerned that COVID will impact their travel plans.

Respondents pointed to a few important factors they're when deciding whether or not to travel this holiday season, including:

• Vaccination status of who they are visiting (47%)
• The number of COVID-19 cases at their destination (47%)
• The vaccination rates at their destination (41%)

To help decide whether you should make the trip, we’ve mapped out COVID cases and vaccination rate data by state. This map also contains information on state mask mandates, vaccine mandates, and emergency declarations. 

What Is an Emergency Declaration?

An emergency declaration is a procedural and policy decision at a local, state, or federal level that lets jurisdiction access resources in response to an emergency or disaster. This might impact things like COVID-19 testing sites or investment in public health campaigns to encourage vaccination.

When looking at the data and deciding if travel is worth the risk, there are also a few additional factors to consider.

The map auto-updates every day when new data is published for both the vaccination rate and COVID-19 case data as well as state policies. To build the map, we used COVID case rate and vaccination rate data from the Centers for Disease Control and Prevention (CDC) COVID Data Tracker. Additional information about state policies was sourced from Kaiser Family Foundation.

Looking at Local Case Numbers

The CDC has travel risk rankings for the entire world, from one (least risky) to four (avoid travel). They currently classify the entire United States as a level four risk: COVID-19 cases are very high.

For level four countries, the CDC states, you should “avoid travel to these destinations. If you must travel to these destinations, make sure you are fully vaccinated before travel.” Before embarking on domestic travel, specifically, the CDC recommends that everyone get fully vaccinated.

But asking everyone to stay put during the holidays is no longer feasible. People are going to travel—especially if they held off last year as they waited for the vaccine. 

In most of the U.S., cases have been dropping, but they’re still much higher than they were one year ago. Pay attention to local case numbers in the areas you’re planning on traveling to, but also in the areas you’re traveling through —that rest stop may also act as a COVID hub. 

What Should You Look For on the Map?

When using our map, take a look at whether cases are higher or lower in the state you're considering traveling to compared to where you currently are. You should keep an eye on vaccination rates, too. For example, if the state you're considering travel to has lower COVID-19 case counts and high vaccination rates it may be a safe destination.

If you're in an area with high or substantial community transmission the CDC recommends you wear a mask—even if you're fully vaccinated. Currently, the entire U.S. is classified under high or substantial community transmission.

It's especially important to wear masks in crowded areas—outdoors or indoors—and any spots you may be in close contact with others. Check the states’ mask mandates and other guidelines and make sure you’re sticking to them.

How to Prepare if You’re Traveling

Unless unavoidable, your family should only travel if you’re all fully vaccinated—two full weeks after a single-dose vaccine or the second dose of a two-shot vaccine.

Before You Go

If you’re eligible, get a booster shot , which should provide extra protection against breakthrough infections, especially if you're high risk or visiting someone who is.

Who Is Eligible for a Booster?

Among adults 18 and older, the CDC now recommends a single booster dose to be administered at least six months after completion of the primary Pfizer or Moderna series or two months after a Johnson & Johnson vaccine.

To be safe when visiting family, especially if they are high risk or unvaccinated, consider getting a COVID test before traveling. The CDC doesn’t recommend testing for vaccinated travelers, but those who are unvaccinated (like children under 5) should have negative test results taken no more than three days before traveling.

While You're There

Take as many precautions as possible when you’re in airports or other places where large numbers of people congregate. Federal law requires mask-wearing in all transportation (planes, trains, buses, rideshares, etc.) and transportation hubs in the U.S., including airports and transit stations. Wear a mask, stay far from others as possible (especially if they’re unmasked), and wash or sanitize hands often.

When traveling, you might consider wearing a KN95 mask as opposed to a cloth mask because they work better. Or double up on masks .

When You Return

When you come back from holiday, vaccinated travelers need to monitor for any COVID symptoms . These include changes to sensations of smell or taste, fever, a persistent cough, chills, loss of appetite, and muscle aches. Isolate yourself and get tested if you feel sick. 

Unvaccinated travelers should quarantine for seven days after traveling and get a COVID test taken three to five days after any leg of travel. Without a test, unvaccinated travelers should quarantine for 10 days.

Traveling With Unvaccinated Children

Now that the Pfizer vaccine is available for children over 5, you should aim to get your kids at least partially vaccinated before traveling. Keep in mind that the Pfizer vaccine is part of a two-dose series, which means both shots need to be spaced 21 days apart.

For kids under 5, though, travel is riskier—not only could they get infected, but they could spread COVID to older, at-risk, or unvaccinated family members. Unvaccinated children over 2 should wear masks whenever they’re in public or near others they don’t live with.

The safest way to travel with unvaccinated children is on short road trips with limited stops. If flying is the only option, choose flights with the fewest layovers. Try to stick to outdoor activities . You should avoid dining indoors, too.

Take normal security precautions in the United States

Back to top

Border with Mexico

Criminal incidents associated with drug trafficking are more frequent at the border with Mexico, in the following states:

If crossing the U.S.– Mexico border by car:

• remain extremely vigilant
• only use officially recognized border crossings
• avoid travelling at night

Petty crime

Petty crime, such as pickpocketing and purse snatching, occurs, particularly in urban centres and tourist locations.

• Don’t leave bags or valuables unattended in parked cars, especially rental vehicles, even in trunks
• Ensure that your belongings, including passports and other travel documents, are secure at all times

Violent crime

Within large urban areas, violent crime more commonly occurs in poor neighbourhoods, particularly from dusk to dawn. It often involves intoxication.  Incidents of violent crime are mainly carried out by gangs or members of organized crime groups but may also be perpetrated by lone individuals. Although violent crime rarely affects tourists:

• be mindful of your surroundings at all time
• verify official neighbourhood crime statistics before planning an outing
• if threatened by robbers, stay calm and don’t resist

Crime Data Explorer – Federal Bureau of Investigation

Gun violence

The rate of firearm possession in the US is high. It’s legal in many states for US citizens to openly carry firearms in public.

Incidences of mass shootings occur, resulting most often in casualties. Although tourists are rarely involved, there is a risk of being in the wrong place at the wrong time. 

Familiarize yourself on how to respond to an active shooter situation.

Active Shooter Event Quick Reference Guide - Cybersecurity and Infrastructure Security Agency

Home break-ins

Canadians living in holiday homes have been the victims of break-ins and burglary.

Make sure you lock windows and doors securely at night and when you are away.

Common criminal strategies

Be on alert for robbery ploys targeting visitors.

Some criminals on highways target travellers leaving airports or other tourist destinations. They signal tourists to stop due to an issue with their vehicle. They then wait for the driver to pull over or exit the car before grabbing exposed valuables. Criminals may also throw items at the windshield, obscuring the view of the road and forcing the driver to pull over. 

If you’re the victim of such a ploy:

• avoid pulling over on the side of the road
• put on your hazard lights and slowly drive to a gas station, police station or other safe and populated area

Demonstrations

Demonstrations may occur. Even peaceful demonstrations can turn violent at any time. They can also lead to disruptions to traffic and public transportation.

• Avoid areas where demonstrations and large gatherings are taking place
• Follow the instructions of local authorities
• Monitor local media for information on ongoing demonstrations

Mass gatherings (large-scale events)

Credit card and ATM fraud occurs, including debit card cloning. Be cautious when using debit or credit cards:

• pay careful attention when your cards are being handled by others
• use ATMs located in well-lit public areas or inside a bank or business
• avoid using card readers with an irregular or unusual feature
• cover the keypad with one hand when entering your PIN
• check for any unauthorized transactions on your account statements

Overseas fraud

There is a threat of terrorism. Terrorist attacks could occur at any time.

Targets could include:

• government buildings, including schools
• places of worship
• airports and other transportation hubs and networks
• public areas such as tourist attractions, restaurants, bars, coffee shops, shopping centres, markets, and hotels 

Always be aware of your surroundings when in public places.

The U.S. Department of Homeland Security (DHS) maintains a public alert system on terrorism to communicate information about terrorist threats.

National Terrorism Advisory System  – U.S. Department of Homeland Security

Hiking and mountaineering

If you intend on hiking, backpacking or skiing:

• never practise these activities alone and always hire an experienced guide from a reputable company
• buy travel insurance that includes helicopter rescue and medical evacuation
• obtain detailed information on hiking routes or ski slopes before setting out and do not venture off marked trails or slopes
• ensure that your physical condition is good enough to meet the challenges of your activity
• ensure that you are properly equipped and well informed about weather and other conditions that may pose a hazard
• inform a family member or friend of your itinerary, including when you expect to be back to camp
• know the symptoms of acute altitude sickness, which can be fatal

We do not make assessments on the compliance of foreign domestic airlines with international safety standards.

Information about foreign domestic airlines

Every country or territory decides who can enter or exit through its borders. The Government of Canada cannot intervene on your behalf if you do not meet your destination’s entry or exit requirements.

We have obtained the information on this page from the US authorities. It can, however, change at any time.

Verify this information with the  Foreign Representatives in Canada .

You must provide proof of your Canadian citizenship upon entry to the U.S. There are several documents that can satisfy this requirement.

Travel by air

Canadian citizens travelling by air to the United States must present one of the following documents:

• a passport, which must be valid for the duration of their stay
• a valid NEXUS card, used at self-serve kiosks at designated airports

This requirement applies to all Canadian citizens, including children, travelling by air to or even just transiting through the United States.

Useful links

• Canadian passports
• Mobile Passport Control app – U.S. Customs and Border Protection

Travel by land or water

As per the Western Hemisphere Travel Initiative (WHTI), Canadian citizens aged 16 years and older must present one of the following documents when entering the United States by land or water:

• a valid passport
• a Trusted Traveler Program card
• an enhanced driver’s licence (EDL) or enhanced identification card (EIC) from a province or territory where a U.S. approved EDL/EIC program has been implemented
• a Secure Certificate of Indian Status

The WHTI-compliant document you choose to use must be valid for the duration of your stay.

Canadian citizens aged 15 years and under entering the United States by land or water require one of the following documents:

• an original or a copy of a birth certificate
• an original Canadian citizenship certificate
• Western Hemisphere Travel Initiative (WHTI ) – U.S. Customs and Border Protection
• Trusted Traveler Programs  – U.S. Customs and Border Protection
• Enhanced Driver’s Licenses: What Are They?  – U.S. Department of Homeland Security
• Apply for a Secure Certificate of Indian Status  – Indigenous Services Canada

Other travel documents

Different entry rules may apply when travelling with a temporary passport or an emergency travel document. Before you leave, check with the closest diplomatic mission for your destination.

• Foreign representatives in Canada

Additional information at borders

Customs officials may ask you to provide your address while in the United States (including Puerto Rico). Customs Border Protection (CBP) officers may also ask for:

• evidence of residential, employment or educational ties to Canada
• proof that the trip is for a legitimate purpose and is of a reasonable length
• proof of sufficient funds to cover your stay     

Dual citizens

Although U.S. authorities don’t formally require dual nationals to carry both a U.S. and a Canadian passport, carrying both documents as proof of citizenship may facilitate your entry into the United States and your return to Canada.

• Travelling as a dual citizen
• Dual Nationality  – U.S. Department of State, Bureau of Consular Affairs

Canadian visitors can usually stay in the United States for 6 months without a visa. You must declare your intended duration of stay upon entry into the United States.

In most circumstances, Canadian citizens don’t require visitor, business, transit or other visas to enter the United States from Canada but there are some exceptions.

Canadians Requiring Visas  – U.S. Embassy & Consulates in Canada

Canadian permanent residents

Canadian permanent residents may need a non-immigrant visa to enter the United States.

You must obtain this visa from the U.S. authorities before entering the country. You must also have a valid passport from your country of citizenship.

Visa Waiver Program

If you are a citizen of a country that is part of the visa waiver program (VWP), you don’t need a visa to enter the U.S. for stays up to 90 days. Instead, you must obtain pre-travel authorization via the Electronic System for Travel Authorization (ESTA) prior your departure.

• Visa Waiver Program  – U.S. Customs and Border Protection
• Countries participating in the Visa Waiver Program  – U.S. Customs and Border Protection

Working in the United States

Most Canadian business travellers may apply for admission at a U.S. port of entry without first obtaining a non-immigrant visa. However, travellers entering the United States in certain business-related categories are required to present specific documents to establish eligibility for admission.

If you plan to work in the United States, contact the nearest U.S. embassy or consulate for specific requirements.

• Foreign Representatives in Canada

Studying in the United States

Canadian citizens don’t need visas to study or participate in a student exchange program in the United States. However, they need to be registered with SEVIS, a U.S. student tracking system. Students must present their registration form to CBP officers each time they enter the United States.

• SEVIS – U.S. Department of Homeland Security
• Canadian students  – U.S. Embassy & Consulates in Canada

Length of stay

If you wish to stay longer than 6 months, you must apply for an extension at the nearest U.S. Citizenship and Immigration Services (USCIS) office once you are in the United States and before the expiry of your initial authorized stay. Immigration officers may ask you to demonstrate that you are a temporary visitor in the United States.

The U.S. government strictly enforces immigration regulations. Remaining in the United States beyond your authorized period of stay can result in serious consequences such as detention or deportation.

There is no set period that you must wait to re-enter the United States after the end of your authorized stay. However, if a CBP officer suspects you are spending more time in the United States than in Canada, it will be up to you to prove to the officer that you are a temporary visitor, not a U.S. resident.

Extend your stay  –  U.S. Citizenship and Immigration Services

Upon entry into the United States, non-U.S. citizens must provide biometrics, such as digital fingerprints and a photograph.

Most Canadian citizens are exempt from this requirement. However, it will apply to Canadian citizens who:

• need a visa or a waiver of ineligibility
• must obtain an I-94 Arrival/Departure Record form to document dates of entry and exit from the country

Random screenings of exempt Canadians have occurred at border crossings and airports. If you feel that your information has been wrongfully collected, you can address the issue directly with the U.S. Department of Homeland Security.

• Arrival/Departure Forms: I-94 and I-94W – U.S. Customs and Border Protection

Electronic devices

U.S. border agents are entitled to search your electronic devices, such as your phones, computers or tablets, when you are entering the United States. They don’t need to provide a reason when requesting a password to open your device.

If you refuse, they may seize your device. The border agent could also delay your travel or deny entry if you are not a U.S. citizen.

Before crossing the border, put your device in airplane mode to ensure remote files don’t get downloaded accidentally.

Inspection of Electronic Devices  – U.S. Customs and Border Protection

Preclearance

The preclearance service provides clearance for entry into the United States for persons and their luggage at a Canadian preclearance airport before departure instead of on arrival in the United States.

When using U.S. preclearance facilities at a Canadian airport, you must meet U.S. entry requirements. You will be interviewed by a U.S. preclearance officer. They are authorized to inspect your luggage and can refuse you entry into the United States.

It’s an offence under Canada’s Preclearance Act to knowingly make a false or deceptive statement to a preclearance officer.  While you are in a preclearance area, you are subject to Canadian law, including:

• the Canadian Charter of Rights and Freedoms
• the Canadian Bill of Rights
• the Canadian Human Rights Act
• Canada’s Preclearance Act
• Canadian criminal law

You may withdraw your request to enter the United States and leave the preclearance area at any time unless a U.S. preclearance officer suspects on reasonable grounds that you have made a false or deceptive statement or obstructed an officer. The officer may then detain you for violations of Canadian law.

Preclearance Locations  –  U.S. Customs and Border Protection

Criminal Record

If you have a criminal record, no matter the severity or the date of the offence, you may be refused entry to the United States. You may also experience problems when travelling through U.S. airport facilities. A pardon for an offence issued by Canadian authorities is not recognized under U.S. law to enter the United States.

If you are ineligible to enter the United States, you may apply directly to U.S. Customs and Border Protection for a temporary waiver of inadmissibility via the nearest U.S. embassy or consulate. Canadian citizens may also apply at land borders.

U.S. ports of entry are computerized and connected to a centralized database. Information is readily available on criminal convictions in both Canada and the United States. Even though you may have entered the United States without hindrance in the past, you could run into difficulty if your record shows a criminal conviction or a previous denial of entry. Attempting to gain entry without a waiver could result in several weeks of detention and a permanent ban from entering the United States.

Boating in U.S. waters

Operators of small pleasure vessels arriving in the United States from a foreign port must report their arrival to U.S. Customs and Border Protection immediately for face-to-face inspection at a designated reporting location.

Some exceptions apply, including under Nexus Marine.

Pleasure Boat Reporting Requirements  – U.S. Customs and Border Protection

You must have a valid Canadian passport to take a cruise from the United States. Some of the countries you visit will not permit entry without a passport. A passport is also important to re-enter the United States at the end of the cruise.

Ship authorities might retain your passport during the cruise, in accordance with their own administrative regulations and to facilitate clearance with U.S. Immigration.

If your passport is kept:

• obtain a receipt
• ensure you recuperate your passport at the end of the cruise
• always keep a photocopy of your passport with you

When examined at a port of entry, cats and dogs must show no signs of diseases communicable to humans. If there is evidence of poor animal health, you may need to get your pet examined by a licensed veterinarian, at your own expense. U.S. authorities may also require a health certificate.

Dogs must be vaccinated against rabies at least 30 days before entry, except for puppies under 3 months of age. Vaccination against rabies is not required for cats.

Other animals are also subject to controls or quarantine requirements.

Yellow fever is a disease caused by a flavivirus from the bite of an infected mosquito.

Travellers get vaccinated either because it is required to enter a country or because it is recommended for their protection.

• There is no risk of yellow fever in this country.

Country Entry Requirement*

• Proof of vaccination is not required to enter this country.

Recommendation

• Vaccination is not recommended.

* It is important to note that country entry requirements may not reflect your risk of yellow fever at your destination. It is recommended that you contact the nearest diplomatic or consular office of the destination(s) you will be visiting to verify any additional entry requirements.

About Yellow Fever

Yellow Fever Vaccination Centres in Canada

Measles is a highly contagious viral disease. It can spread quickly from person to person by direct contact and through droplets in the air.

Anyone who is not protected against measles is at risk of being infected with it when travelling internationally.

Regardless of where you are going, talk to a health care professional before travelling to make sure you are fully protected against measles.

  Hepatitis B is a risk in every destination. It is a viral liver disease that is easily transmitted from one person to another through exposure to blood and body fluids containing the hepatitis B virus.  Travellers who may be exposed to blood or other bodily fluids (e.g., through sexual contact, medical treatment, sharing needles, tattooing, acupuncture or occupational exposure) are at higher risk of getting hepatitis B.

Hepatitis B vaccination is recommended for all travellers. Prevent hepatitis B infection by practicing safe sex, only using new and sterile drug equipment, and only getting tattoos and piercings in settings that follow public health regulations and standards.

 The best way to protect yourself from seasonal influenza (flu) is to get vaccinated every year. Get the flu shot at least 2 weeks before travelling.  

 The flu occurs worldwide. 

•  In the Northern Hemisphere, the flu season usually runs from November to   April.
•  In the Southern Hemisphere, the flu season usually runs between April and   October.
•  In the tropics, there is flu activity year round. 

The flu vaccine available in one hemisphere may only offer partial protection against the flu in the other hemisphere.

The flu virus spreads from person to person when they cough or sneeze or by touching objects and surfaces that have been contaminated with the virus. Clean your hands often and wear a mask if you have a fever or respiratory symptoms.

Coronavirus disease (COVID-19) is an infectious viral disease. It can spread from person to person by direct contact and through droplets in the air.

It is recommended that all eligible travellers complete a COVID-19 vaccine series along with any additional recommended doses in Canada before travelling. Evidence shows that vaccines are very effective at preventing severe illness, hospitalization and death from COVID-19. While vaccination provides better protection against serious illness, you may still be at risk of infection from the virus that causes COVID-19. Anyone who has not completed a vaccine series is at increased risk of being infected with the virus that causes COVID-19 and is at greater risk for severe disease when travelling internationally.

Before travelling, verify your destination’s COVID-19 vaccination entry/exit requirements. Regardless of where you are going, talk to a health care professional before travelling to make sure you are adequately protected against COVID-19.

In this destination, rabies  may be present in some wildlife species, including bats. Rabies is a deadly disease that spreads to humans primarily through bites or scratches from an infected animal. 

If you are bitten or scratched by an animal while travelling, immediately wash the wound with soap and clean water and see a health care professional. 

Before travel, discuss rabies vaccination with a health care professional. It may be recommended for travellers who will be working directly with wildlife. 

Polio (poliomyelitis) is an infectious disease that can be prevented by vaccination. It is caused by poliovirus type 1, 2 or 3. Circulating vaccine-derived poliovirus 2 (cVDPV2) is present in this country. Polio is spread from person to person and through contaminated food and water. Infection with the polio virus can cause paralysis and death in individuals of any age who are not immune.

Recommendations:

• Be sure that your polio vaccinations are up to date before travelling. Polio is part of the routine vaccine schedule for children in Canada.
• One booster dose of the polio vaccine is recommended as an adult .

Safe food and water precautions

Many illnesses can be caused by eating food or drinking beverages contaminated by bacteria, parasites, toxins, or viruses, or by swimming or bathing in contaminated water.

• Learn more about food and water precautions to take to avoid getting sick by visiting our eat and drink safely abroad page. Remember: Boil it, cook it, peel it, or leave it!
• Avoid getting water into your eyes, mouth or nose when swimming or participating in activities in freshwater (streams, canals, lakes), particularly after flooding or heavy rain. Water may look clean but could still be polluted or contaminated.
• Avoid inhaling or swallowing water while bathing, showering, or swimming in pools or hot tubs. 

Insect bite prevention

Many diseases are spread by the bites of infected insects such as mosquitoes, ticks, fleas or flies. When travelling to areas where infected insects may be present:

• Use insect repellent (bug spray) on exposed skin
• Cover up with light-coloured, loose clothes made of tightly woven materials such as nylon or polyester
• Minimize exposure to insects
• Use mosquito netting when sleeping outdoors or in buildings that are not fully enclosed

To learn more about how you can reduce your risk of infection and disease caused by bites, both at home and abroad, visit our insect bite prevention page.

Find out what types of insects are present where you’re travelling, when they’re most active, and the symptoms of the diseases they spread.

Zika virus may be a risk in some areas of the United States. 

Zika virus is primarily spread through the bite of an infected mosquito. It can also be sexually transmitted. Zika virus can cause serious birth defects.

Visit the Centers for Disease Control and Prevention’s webpage Areas at Risk for Zika  for the most up-to-date information on Zika risk in the United States.

During your trip to a Zika risk area:

• Prevent mosquito bites at all times.
• Use condoms correctly or avoid sexual contact, particularly if you are pregnant.

If you are pregnant or planning a pregnancy, you should discuss the potential risks of travelling to areas where Zika is a risk with your health care provider. You may choose to avoid or postpone travel to these areas.

For more information, see Zika virus: Pregnant or planning a pregnancy .

• In this country, risk of  dengue  is sporadic. It is a viral disease spread to humans by mosquito bites.
• Dengue can cause flu-like symptoms. In some cases, it can lead to severe dengue, which can be fatal.
• Visit the Centers for Disease Control and Preventions webpage on Dengue in the U.S. States and Territories for the most up-to-date information on dengue outbreaks in the United States
• Mosquitoes carrying dengue typically bite during the daytime, particularly around sunrise and sunset.
• Protect yourself from mosquito bites . There is no vaccine or medication that protects against dengue fever.

Animal precautions

Some infections, such as rabies and influenza, can be shared between humans and animals. Certain types of activities may increase your chance of contact with animals, such as travelling in rural or forested areas, camping, hiking, and visiting wet markets (places where live animals are slaughtered and sold) or caves.

Travellers are cautioned to avoid contact with animals, including dogs, livestock (pigs, cows), monkeys, snakes, rodents, birds, and bats, and to avoid eating undercooked wild game.

Closely supervise children, as they are more likely to come in contact with animals.

Human cases of avian influenza have been reported in this destination. Avian influenza   is a viral infection that can spread quickly and easily among birds and in rare cases it can infect mammals, including people. The risk is low for most travellers.

Avoid contact with birds, including wild, farm, and backyard birds (alive or dead) and surfaces that may have bird droppings on them. Ensure all poultry dishes, including eggs and wild game, are properly cooked.

Travellers with a higher risk of exposure include those: 

• visiting live bird/animal markets or poultry farms
• working with poultry (such as chickens, turkeys, domestic ducks)
• hunting, de-feathering, field dressing and butchering wild birds and wild mammals
• working with wild birds for activities such as research, conservation, or rehabilitation
• working with wild mammals, especially those that eat wild birds (e.g., foxes)

All eligible people are encouraged to get the seasonal influenza shot, which will protect them against human influenza viruses. While the seasonal influenza shot does not prevent infection with avian influenza, it can reduce the chance of getting sick with human and avian influenza viruses at the same time.

Person-to-person infections

Stay home if you’re sick and practise proper cough and sneeze etiquette , which includes coughing or sneezing into a tissue or the bend of your arm, not your hand. Reduce your risk of colds, the flu and other illnesses by:

•   washing your hands often
• avoiding or limiting the amount of time spent in closed spaces, crowded places, or at large-scale events (concerts, sporting events, rallies)
• avoiding close physical contact with people who may be showing symptoms of illness 

Sexually transmitted infections (STIs) , HIV , and mpox are spread through blood and bodily fluids; use condoms, practise safe sex, and limit your number of sexual partners. Check with your local public health authority pre-travel to determine your eligibility for mpox vaccine.  

Medical services and facilities

Health care is excellent. Service is available throughout the country. However, treatment costs are expensive.

All hospitals must accept and treat emergencies, regardless of the person’s ability to pay. Clients will, however, be charged for all services rendered. Foreign visitors without travel health insurance will have to pay out of pocket for their medical treatment.

Make sure you get travel insurance that includes coverage for medical evacuation and hospital stays.

Travel health and safety

There are restrictions and prohibitions on the import of certain prescription drugs into the United States.

Some medication that can be purchased over-the-counter in Canada is restricted to prescription-only status in the United States.

• Bring sufficient quantities of your medication
• Ensure to have a physician’s note explaining your medical condition, if applicable

Keep in Mind...

The decision to travel is the sole responsibility of the traveller. The traveller is also responsible for his or her own personal safety.

Be prepared. Do not expect medical services to be the same as in Canada. Pack a   travel health kit , especially if you will be travelling away from major city centres.

You must abide by local laws.

Learn about what you should do and how we can help if you are arrested or detained abroad .

Laws vary greatly from state to state. Consult the website of the state you wish to visit prior to arrival.

Penalties and transfer of offenders

A serious violation of the law may lead to a jail sentence or, in some states, a death sentence. Canadian citizenship confers no immunity, special protection or rights to preferential treatment.

If a jail sentence is imposed, it will be served in a U.S. prison, unless a request for a transfer to a Canadian prison is approved by the United States and Canada. Both countries have signed a treaty that permits a Canadian imprisoned in the United States to request a transfer to complete the sentence in a Canadian prison.

Penalties for possession, use or trafficking of illegal drugs are severe. Convicted offenders can expect lengthy jail sentences and heavy fines.

Drugs, alcohol and travel

Although the possession of cannabis is legal in some U.S. states, it remains illegal under U.S. federal laws in any form and quantity, making it illegal to bring across the Canada-U.S. border.

Don’t attempt to cross the Canada-U.S. border with any amount of cannabis in any form, even if you are traveling to a U.S. state that has legalized possession of cannabis. If you do so, you can expect legal prosecution and fines, and possibly jail time.

• Entry/exit requirements pertaining to cannabis

Prescription medication

Personal medication may be subject to U.S. drug importation laws and regulations.

In general, personal importation of a 90-day supply of medication is allowed. U.S. Customs and Border Protection has absolute discretion to allow or not your Canadian-purchased medication into the United States.

When taking any prescription medication to the United States, it’s important to:

• take only the quantity that you would normally take for the number of days you will be in the United States, plus an additional week’s worth
• pack medicines in their original packaging with the dispensary label intact that shows your name and other pertinent information such as the drug’s name, dosage and DIN (drug identification number)
• keep a duplicate of your original prescription, listing both the generic and trade names of the drug
• have a physician’s note explaining your condition and the reason for you to be legitimately carrying syringes, if applicable

International Child Abduction

The Hague Convention on the Civil Aspects of International Child Abduction is an international treaty. It can help parents with the return of children who have been removed to or retained in certain countries in violation of custody rights. The convention applies between Canada and the United States.

If your child was wrongfully taken to, or is being held in the United States, and if the applicable conditions are met, you may apply for the return of your child to the American court.

If you are in this situation:

• act as quickly as you can
• contact the Central Authority for your province or territory of residence for information on starting an application under The Hague Convention
• consult a lawyer in Canada and in the United States to explore all the legal options for the return of your child
• report the situation to the nearest Canadian government office abroad or to the Vulnerable Children's Consular Unit at Global Affairs Canada by calling the Emergency Watch and Response Centre

If your child was removed from a country other than Canada, consult a lawyer to determine if The Hague Convention applies.

Be aware that Canadian consular officials cannot interfere in private legal matters or in another country's judicial affairs.

• Canadian embassies and consulates by destination
• Request emergency assistance

Expedited removal

U.S. Customs and Border Protection can bar non-citizens from the United States for five years if, in their judgment, the individuals presented false documentation or misrepresented themselves. Lying to a customs official is a serious offence.

There is no formal appeal process under expedited removal. However, if you believe the law has been misapplied in your case, you can request a supervisory review by writing to the U.S. Citizenship and Immigration Services district director responsible for the port of entry where the decision was made.

Be equally careful about who and what you carry in your vehicle. As the driver, you could be held responsible for the misdeeds and belongings of your passengers, even if you were unaware of the problem.

The currency in the United States is the U.S. dollar (USD).

Canadian currency and personal cheques from Canadian banks are not widely accepted. Most banking transactions require a U.S. bank account.

There’s no limit to the amount of money that you may legally take into or out of the United States. However, you must declare to U.S. Customs and Border Protection:

• if you carry more than US$10,000 (in cash, cheque, money order,      travellers’ cheque or any other convertible asset) into or out of the      United States
• if you will receive more than US$10,000 while in the United States

Failure to comply can result in civil and criminal penalties, including seizure of the currency or monetary instruments.

Natural disasters can occur at any time.

Risk Levels

  take normal security precautions.

Take similar precautions to those you would take in Canada.

  Exercise a high degree of caution

There are certain safety and security concerns or the situation could change quickly. Be very cautious at all times, monitor local media and follow the instructions of local authorities.

IMPORTANT: The two levels below are official Government of Canada Travel Advisories and are issued when the safety and security of Canadians travelling or living in the country or region may be at risk.

  Avoid non-essential travel

Your safety and security could be at risk. You should think about your need to travel to this country, territory or region based on family or business requirements, knowledge of or familiarity with the region, and other factors. If you are already there, think about whether you really need to be there. If you do not need to be there, you should think about leaving.

  Avoid all travel

You should not travel to this country, territory or region. Your personal safety and security are at great risk. If you are already there, you should think about leaving if it is safe to do so.

Evaluating the U.S. Department of State Travel Advisory System

Many colleges and universities, including Northwestern, pay close attention U.S. Department of State (DOS) consular announcements, which are disseminated to the public to help assess travelers’ risks. It’s important for travelers to understand the different announcement types and sources.

The Consular Travel Advisory System

Under new DOS Travel Advisory system every country is assigned a color-coded risk rating from one to four, defined as:

• Level 1 – Exercise Normal Precautions: This is the lowest advisory level for safety and security risk.
• Level 2 – Exercise Increased Caution: Be aware of heightened risks to safety and security. The Department of State provides additional advice for travelers in these areas in the Travel Advisory. 
• Level 3 – Reconsider Travel: Avoid travel due to serious risks to safety and security. The Department of State provides additional advice for travelers in these areas in the Travel Advisory. 
• Level 4 – Do Not Travel: This is the highest advisory level due to greater likelihood of life-threatening risks. During an emergency, the U.S. government may have very limited ability to provide assistance. The Department of State advises that U.S. citizens not travel to the country or leave as soon as it is safe to do so. The Department of State provides additional advice for travelers in these areas in the Travel Advisory.   

Additional country-specific information is provided in each advisory, including clearer, actionable steps for that travelers can take to mitigate risk. (See Risk Indicators below). The DOS will update the advisories as needed, based on changes to security and safety information.

Risk Indicators

By using established risk indicators, the Travel Advisories at levels 2-4 provide clear reasons for the level assigned:

• E - Time-Limited Event:  A short-term event, such as an election, sporting event or other incident that may post a safety risk.  
• C – Crime: Widespread violent or organized crime is present in areas of the country. Local law enforcement may have limited ability to respond to serious crimes.
• T – Terrorism: Terrorist attacks have occurred and/or specific threats against civilians, groups, or other targets may exist.
• U – Civil Unrest: Political, economic, religious, and/or ethnic instability exist and may cause violence, major disruptions, and/or safety risks.
• N – Natural Disaster: A natural disaster, or its aftermath, poses danger.
• H – Health: Health risks, including current disease outbreaks or a crisis that disrupts a country’s medical infrastructure, are present. The issuance of a Centers for Disease Control Travel Notice may be a factor.
• K– Kidnapping or Hostage Taking : Criminal or terrorist individuals or groups have threatened to and / or have seized or detained and threatened to kill,  injure or continue to detain individuals in order to compel a third party (including a governmental organization) to do or abstain from doing something as a condition of release.
• D – Wrongful Detention: The risk of wrongful detention of U.S. nationals by a foreign government exists.
• O – Other: There are potential risks not covered by previous risk indicators.

U.S. embassies and consulates will now issue Alerts to replace the Emergency Messages and Security Messages. Alerts will inform travelers of specific safety and security concerns in a country and will be labeled according to their issue: Security Alert; Health Alert; Weather Alert; or Demonstration Alert. Recent Alerts for a country appear below the Travel Advisory. Alerts can also be found on individual embassy or consulate websites.

Safety & Security Overseas

Cdc yellow book 2024.

Author(s): Virginia Lehner

US citizens traveling abroad face a wide range of risks not generally prevalent in the United States. These risks include sanitation issues (e.g., non-potable water), increased risk for traffic accidents due to poor road conditions and unfamiliarity with local norms, local insectborne illness or disease vectors, injury from adventure tourism or overexposure to unfamiliar climates, and violence ranging from petty theft to terrorism.

Travelers going overseas, particularly tourists, can also face additional challenges in seeking help when they find themselves in distress. Language, culture, and local laws can be barriers, and travelers might not have an immediately accessible network of friends or family to assist them in an emergency. Local government responses to accidents or crime might not be what travelers expect; in some instances, an effective local government might not even exist to respond. Travelers should research conditions at their destination before departure to learn what risks they could likely face and make plans to mitigate those risks abroad.

Informed Travel

As indicated above, travelers should make informed decisions prior to departure, based on clear, timely, and reliable safety and security information. The Bureau of Consular Affairs (CA) within the US Department of State (the organization charged with protecting US citizens abroad) provides would-be travelers with a broad range of information for every country in the world through its webpages, Travel.State.Gov and US Embassy and Consulate .

Travel Advisories & Travel to High-Risk Areas

At the broadest level, CA assigns every country a metrics-based travel advisory level ranging from 1: Exercise normal precautions to 4: Do not travel. Travelers can see travel advisories at  Travel.State.Gov ; accompanying country information pages describe the risks and conditions and the actions travelers should take to mitigate risks in each country. Country information pages provide extensive travel information, including details about entry and exit requirements, local laws and customs, health conditions, accessibility for travelers with disabilities and for other key groups, typical scams and other crimes, transportation safety, and other relevant topics. The Department of State also warns people not to visit  certain high-risk countries or areas because of local conditions and limited ability to provide consular services in those places.

US embassies and consulates abroad also issue event-based alerts to inform US citizens of specific safety, security, or health concerns that put travelers at immediate risk (e.g., civil aviation risks, crime threats, demonstrations, health events, weather events).

Smart Traveler Enrollment Program (STEP)

Advise US citizen travelers to enroll with the Department of State’s Smart Traveler Enrollment Program (STEP). A free service, STEP allows enrollees to receive information and alerts from local US embassies or consulates about safety, security, or health conditions at their destination. STEP can also help the local embassy or consulate locate missing US citizens or contact them in an emergency (e.g., civil unrest, a family emergency, natural disasters).

Preparing Friends & Family

The Department of State advises travelers to share their itinerary with friends and family, including the names and contact information for travel agencies, planned tours, and lodging. Travelers should establish reasonable expectations for “check-in” communications with family and friends. In addition to having their own copies, travelers also should provide trusted friends and family with copies of important documents like passports, visas, health insurance cards, and credit cards in case any of these items are lost or stolen.

Medical Insurance

The US government does not provide medical insurance for US travelers overseas and will not pay costs for travelers receiving international medical care. Medicare and Medicaid do not cover these costs, nor do many private domestic health insurance plans. Thus, travelers should purchase supplemental insurance prior to travel (see Sec. 6, Ch. 1, Travel Insurance, Travel Health Insurance & Medical Evacuation Insurance ). Because travel insurance policy coverages vary, travelers should carefully read the terms to make sure the policy fits their needs. Travelers might need additional insurance coverage to cover the costs of emergency medical care, medical transport back to the United States, travel and accommodation costs in the event of interrupted or delayed travel, 24-hour contact services, and treatment received overseas for any preexisting conditions, including pregnancy.

US citizens are subject to local laws during travel abroad. Travelers who violate those laws—even unknowingly—can face arrest, imprisonment, or deportation. In addition, some crimes are prosecutable both in the United States and in the country where the crime was committed. US citizens arrested or detained abroad should ask local law enforcement or prison officials to notify the US embassy or consulate immediately.

Faith-Based Travelers

Faith-based travel encompasses a wide range of activities (e.g., attending pilgrimages, participating in service projects, conducting missionary work, taking part in faith-based tours). Millions of faith-based travelers participate safely in some type of religious travel every year. In addition to being aware of basic country conditions that impact all travelers, US faith-based travelers should know that in some countries, conducting religious activities without proper registration, or at all, is a crime.

LGBTQ+ Travelers

Lesbian, gay, bisexual, transgender, queer, and intersex (LGBTQ+) travelers face unique challenges when traveling abroad (see Sec. 2, Ch. 13, LGBTQ+ Travelers ). Laws and attitudes in some countries might negatively affect safety and ease of travel for LGBTQ+ persons, and legal protections vary between countries. Many countries do not legally recognize same-sex marriage and >70 countries criminalize consensual same-sex sexual relations, sometimes with severe punishment. Travelers should review the Human Rights Report for further details before travel.

Travelers with Disabilities

Each country has its own laws regarding accessibility for, or discrimination against, people with physical, sensory, intellectual, or mental disabilities . Enforcement of accessibility and other laws relating to people with disabilities is inconsistent (see Sec. 3, Ch. 2, Travelers with Disabilities ).

Travelers with Dual Nationality

Countries have different regulations for dual nationals; some do not permit dual nationality, while others infer dual nationality based on the birthplace of a traveler’s parent. US citizens should check with the embassy of any country for relevant nationality laws before travel.

Crime, Crises & Terrorism

Crime is one of the most common threats to the safety of US citizens abroad. Travelers should research crime trends and patterns at their destination using the Overseas Security Advisory Council Country Security Reports , which provide baseline security information for every country around the world. Although strategies to avoid becoming a crime victim are, for the most part, the same everywhere, travel health providers should stress the following points with international travelers:

• Avoid accommodations on the ground floor or immediately next to the stairs, and lock all windows and doors.
• Do not wear expensive clothing or accessories.
• If confronted in a robbery, give up all valuables and do not resist attackers. Resistance can escalate to violence and result in injury or death.
• Limit travel at night; travel with a companion, and vary routine travel habits.
• Take only recommended, safe modes of local transportation.

Crime victims should contact the local authorities and the nearest US embassy, consulate, or consular agency for assistance. The Department of State can help replace stolen passports, contact family and friends, identify health care providers, explain the local criminal justice process, and connect victims of crime with available resources, including a list of local attorneys and medical providers. The Department of State does not have the legal authority to conduct a criminal investigation, prosecute crimes, or provide legal advice or counsel.

Whether traveling or living outside the United States, US citizens should prepare for potential crises . The Department of State is committed to assisting US citizens who become victims of crime, who need assistance during a crisis or a natural disaster, or who need consular services (e.g., replacing a lost or stolen passport, providing a loan to return to the United States). The Department of State also can attempt to locate missing US citizens abroad. Nevertheless, US citizens should proactively research resources available for the country or countries where they are traveling or residing, stay connected with the nearest US embassy or consulate, and create personal safety plans.

Despite being a worldwide threat and cause for concern, terrorist attacks have involved relatively few international travelers. Past attacks have included assassinations, bombings, hijackings, kidnappings, and suicide operations. Bombings are typically conducted with the use of improvised explosive devices (IEDs), but biological and chemical attacks remain a concern in some high-threat countries. Potential targets include business offices, clubs, hotels, houses of worship, public transportation systems, residential areas, restaurants, schools, shopping malls, high-profile sporting events, and other tourist destinations where people gather in large numbers. To reduce their chances of becoming victims of terrorism, travelers should be cautious of unexpected packages; avoid wearing clothing that identifies them as a tourist (e.g., a T-shirt bearing the US flag or the logo of a favorite US-based sports team); look out for unattended bags or packages in public places and other crowded areas; and try to blend in with the locals. These strategies incorporate the same defensive alertness and good judgment that people should use to prevent becoming victims of crime. Awareness is key, and travelers should be knowledgeable of their surroundings and adopt protective measures.

15 Countries the US State Department Says Americans Should Not Travel To

Posted: June 21, 2024 | Last updated: June 21, 2024

Traveling can be one of the most rewarding experiences, but keeping safety in mind is essential. Some destinations might look alluring but come with serious risks that can’t be ignored.

The US State Department has advised against traveling to certain countries due to various threats. Here’s the list. Understand why these places are currently off-limits.

As of May 23, 2024, the US State Department issued a level 4 travel warning, its highest alert, advising US citizens to avoid traveling to Venezuela.

Due to crime, civil unrest, kidnapping, arbitrary enforcement of laws, wrongful detentions, terrorism, and poor health infrastructure. You don’t want your vacation turning into a “ Lost ” episode, do you?

Terrorism, kidnapping, armed conflict, civil unrest, and limited US government capacity to assist make Iraq a high-risk destination.

As of April 2024, the US State Department issued a Level 4 travel advisory for Somalia, advising against travel to this destination for US citizens.

Crime, terrorism, civil unrest, health issues, kidnapping, and piracy are rampant. There is no Johnny Depp here, just real pirates.

Effective June 7, 2024, the US State Department recommended that US citizens avoid traveling to Libya as a Level 4 advisory, indicating “ Do Not Travel. “

Crime, terrorism, civil unrest, kidnapping, and armed conflict are significant concerns. It’s not the Mediterranean getaway you’re dreaming of.

The risk of kidnapping, arbitrary arrest, and detention on spurious charges is high. Keep your “ 007 ” aspirations in check.

Burma (Myanmar)

Civil unrest, armed conflict, wrongful detentions, and the presence of landmines make Myanmar risky. It’s not the pretty peaceful temple trek you were hoping for.

As of May 18, 2024, the US State Department issued a Level 4 travel advisory for Russia advising US citizens against traveling to the region.

Due to the Russian invasion of Ukraine, potential harassment, arbitrary enforcement of laws, and limited US assistance, Russia is a no-go. Red Square can wait.

As of May 9, 2024, the US Department of State advised against travel with a Level 4: Do Not Travel advisory. Crime, terrorism threats, and kidnapping risks are prevalent. Timbuktu isn’t going anywhere.

Effective May 9, 2024, the US State Department advised against traveling to Yemen, assigning a Level 4: Do Not Travel advisory due to hazardous conditions.

Terrorism, civil unrest, health risks, kidnapping, armed conflict, and landmines are significant threats. Yemen is not your Arabian nights fantasy.

Effective January 30, 2024, the US Department of State issued a Level 4: Do Not Travel advisory against travel to Syria.

Terrorism, civil unrest, kidnapping, armed conflict, and risk of detentions are high. Stay safe, stay away.

North Korea

Effective June 4, 2024, the US State Department issued a Level 4 “ Do Not Travel ” advisory for North Korea out of safety considerations.

The serious risk of arrest and long-term detention of US nationals means all those “ mystery ” and “ forbidden ” vibes are not worth it.

Central African Republic

Avoid traveling to the Central African Republic (CAR) as Embassy Bangui may have limited capacity to assist U.S. citizens. Crime, civil unrest, kidnapping, and armed conflict are rampant. It’s not the safari you’re looking for.

Effective June 3, 2024, the US State Department for Haiti’s travel advisory is at Level 4, indicating “ Do Not Travel. “

Kidnapping, violent crime, and the US ordering the departure of non-emergency personnel make it a high-risk area.

Afghanistan

The US State Department issued a Level 4 “ Do Not Travel ” advisory for Afghanistan effective May 31, 2024. Terrorism, risk of wrongful detention, kidnapping, and crime elevate the dangers. Sorry, the Silk Road will have to wait.

Terrorism, civil unrest, kidnapping, armed conflict, and crime make Sudan a no-go zone. Do not attempt to make any travel plans for this region.

Travel advisories might dampen your wanderlust, but safety should always come first. Stay informed, stay prepared, and make smart travel choices.

About Middle East Respiratory Syndrome (MERS)

• MERS is a viral respiratory illness.
• Most MERS cases have been detected in countries in or near the Arabian Peninsula.
• MERS represents a very low risk to the general public in the United States.

More Information

Middle East Respiratory Syndrome (MERS) is a viral respiratory illness caused by a coronavirus called Middle East respiratory syndrome coronavirus (MERS-CoV). The virus can spread from camels to people through direct physical contact. Limited human-to-human transmission is possible. MERS has caused severe respiratory disease in most diagnosed cases, and many of those patients died. Typical symptoms include fever, cough, and shortness of breath.

Most MERS cases have been detected in countries in or near the Arabian Peninsula. However, a number of cases linked to travel have been detected in countries outside this region.

For more information about travel guidelines for your destination, visit CDC's Travelers' Health site .

Did you know?‎

CDC does not recommend that anyone change travel plans to, in, or near the Arabian Peninsula because of MERS.

Countries in or near the Arabian Peninsula that have reported MERS cases : Bahrain, Iran, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, United Arab Emirates (UAE), and Yemen. Countries outside of the Arabian Peninsula with MERS cases linked to travel : Algeria, Austria, China, Egypt, France, Germany, Greece, Italy, Malaysia, Netherlands, Philippines, Republic of Korea, Thailand, Tunisia, Turkey, United Kingdom, and the United States. Only two patients in the United States have ever tested positive for MERS . Both cases were in May 2014 and were among healthcare providers who lived and worked in Saudi Arabia.

Signs and symptoms

Most people with confirmed MERS-CoV infection have had severe respiratory illness. MERS symptoms usually appear 5 or 6 days after a person is exposed. However, symptoms can appear as early as 2 days and up to 14 days after exposure.

Common symptoms of MERS include:

• Shortness of breath

Some people may also have diarrhea, nausea, or vomiting. It is also possible that someone with MERS may have only mild symptoms or no symptoms.

In most known MERS cases, the infected person developed pneumonia. Additional complications such as kidney failure have also occurred. About 3 or 4 out of every 10 people reported with a MERS infection died.

Most of the people who die from MERS had at least one preexisting medical condition. Certain conditions may increase the risk of getting severe complications from MERS. These include:

• Cardiovascular disease, including high blood pressure
• Chronic lung disease
• Chronic heart disease
• Chronic kidney disease

Who is at risk

You may be at increased risk of getting MERS if you:

• Worked in or visited a healthcare setting
• Had direct physical contact with camels (including touching or grooming)
• Had close contact with a person who was sick with fever or respiratory symptoms
• Had close contact in the past 14 days with someone who was sick with fever or respiratory symptoms of unknown cause after they had traveled in or near the Arabian Peninsula
• Had close contact in the past 14 days with someone who has tested positive for MERS

When to call your healthcare provider‎

How it spreads.

The virus that causes MERS can spread through respiratory secretions, such as saliva or mucous, of infected animals or people. The MERS virus is mostly found in camels (dromedaries), and direct physical contact with camels can lead to transmission to humans. People infected through contact with camels can then spread the virus to other people. All reported person-to-person transmissions of MERS have been linked to someone who had been in or near the Arabian Peninsula.

Large MERS outbreaks from person-to-person spread have occurred in healthcare facilities treating patients with MERS. Some spread can occur in households through close contact (like sharing a bed or caring for someone who is sick). The largest known outbreak of MERS outside the Arabian Peninsula occurred in the Republic of Korea in 2015. Multiple healthcare facilities were affected by the outbreak, which was associated with a traveler returning from the Arabian Peninsula.

Researchers continue to investigate clusters of MERS cases to better understand how the virus spreads.

No vaccine exists to protect people against MERS. CDC's Respiratory Virus Guidance provides practical recommendations and information to help people lower health risks from respiratory viral illnesses.

For travelers, the World Health Organization recommends:

• Wash your hands before and after touching camels.
• Avoid drinking raw camel milk or camel urine or eating meat (including camel meat) that has not been properly cooked.
• If you are someone at higher risk for severe MERS illness, avoid close contact with camels.

No specific antiviral treatment is recommended for MERS. People with MERS often receive supportive medical care and care to help relieve symptoms.
