- The U.S. State Department issued Level 4 advisories for 22 countries and regions as of March 2026.
- Travelers face extreme risks including terrorism, kidnapping, and wrongful detention in these high-danger zones.
- Consular assistance is extremely limited or unavailable in destinations like Afghanistan, Iraq, and Haiti.
(AFGHANISTAN) — The U.S. State Department maintained Level 4: Do Not Travel advisories for 22 countries and regions as of March 2026, warning Americans to avoid destinations where armed conflict, terrorism, crime, civil unrest, health crises, kidnapping, wrongful detention and natural disasters pose life-threatening risks.
Afghanistan and Iraq remained on that list after recent updates, with Afghanistan’s advisory issued on 02/20/2026 and Iraq’s on 03/02/2026. The department said consular assistance in such places is extremely limited or unavailable.
The designation is the State Department’s most severe travel warning. It tells U.S. citizens not to travel to destinations where risks to personal safety are extreme and unavoidable.
Among the effects, U.S. embassies may evacuate staff or restrict operations, leaving Americans without evacuation aid, legal help during arrests or emergency medical assistance. The State Department says it “may have very limited or no ability to help, including during an emergency,” and urges citizens already there to depart immediately if possible.
Level 4 advisories are not travel bans. They are formal warnings against travel, often issued alongside embassy closures or other restrictions that make assistance hard to obtain.
What the Level 4 list includes
The current list spans conflict zones, countries facing militant violence, and places where Americans face detention or severe limits on U.S. access. In some cases, risks apply nationwide. In others, they reflect conditions so widespread that the State Department assigns the highest warning level to the country or region as a whole.
Afghanistan’s advisory cites unrest, crime, health, kidnapping, terrorism, wrongful detention and natural disasters. Iraq’s warning cites unrest, kidnapping, terrorism and other risks.
Other entries on the list include Belarus, issued 12/29/2025; Burkina Faso, 04/16/2025; Burma (Myanmar), 05/12/2025; Haiti, listed as ongoing Level 4; Iran, under recent escalation; Lebanon, 02/23/2026; and Libya, listed as ongoing.
The roster also includes Mali, issued 01/09/2026; Niger, ongoing; North Korea, ongoing; Russia, ongoing; Somalia, 05/14/2025; South Sudan, 11/13/2025; and Sudan, ongoing.
Rounding out the list are Syria, issued 12/11/2025; Ukraine, 11/14/2024 (ongoing); Venezuela, ongoing; Yemen, 12/19/2025; Central African Republic, listed; and Gaza, listed.
Why each country is flagged
The State Department ties those advisories to differing combinations of threats. Ukraine is listed for active conflict and missile strikes. Somalia is listed for unrest, crime, kidnapping, terrorism and health. Haiti is listed for civil unrest, gang violence and kidnapping.
Russia and Iran appear on the list in part because of arbitrary or wrongful detention concerns. North Korea remains under Level 4 because of restricted access and wrongful detention, and U.S. passport validation is required.
The department reviews Level 4 advisories at least every six months. It can issue urgent updates more quickly during wars, outbreaks or other fast-moving crises.
That process produced several recent changes. Lebanon’s advisory was updated on February 23, 2026, due to cross-border attacks, while Afghanistan and Iraq also received fresh advisories this year.
A separate worldwide caution issued on March 22, 2026 urged heightened vigilance everywhere because of terrorism threats. That notice sits alongside the country-specific warnings rather than replacing them.
Recent tensions involving Iran also prompted fresh warnings for the Middle East. Those developments followed U.S. strikes and President Trump’s demand for “unconditional surrender,” which disrupted flights and stranded passengers.
What the warning means for travelers
For travelers, the practical meaning of Level 4: Do Not Travel extends beyond the warning itself. Airports may close, borders may seal, and visa or entry conditions may shift with little notice.
Ukraine is an example of airport disruption and Sudan is an example of sealed borders. Russia requires politicized invitations, adding another barrier for travelers.
Insurance can be another obstacle. Most policies explicitly deny coverage for trips to Level 4 countries, leaving travelers responsible for the full cost of medical evacuations, trip cancellations or losses tied to theft and violence.
Medical evacuations can exceed $100,000+. One traveler’s $50,000 evacuation from Haiti was denied in 2025.
That insurance gap can hit both leisure travelers and people making family or immigration-related trips. A valid visa does not remove the risks created by closed embassies, suspended services or security threats on the ground.
Effects on visas, immigration and family travel
For visa holders and immigrants, the warning can complicate renewals, new applications and even return travel. Existing visas may remain valid, but overstays or renewals can become impossible without embassy access, including in places such as Yemen and Libya where U.S. operations are closed or heavily restricted.
New applications can also face delays or denials. Niger and Mali limit processing, while Iran requires sponsors amid heightened tensions.
Green card holders and dual nationals can face separate risks if they return through a Level 4 country. Detention concerns affect Iranian-Americans, and third-country processing is advised.
Family-based immigration cases can also be affected. Humanitarian parole remains rare, while asylum claims from Level 4 origins such as Venezuela and Haiti face backlogs exceeding 1 million cases.
Across parts of Africa, travel restrictions now intersect with visa policy. Burkina Faso, Chad, Mali, and Niger have suspended U.S. visas in reciprocity for U.S. entry bans on their citizens.
Over 20 countries fully ban U.S. entry in reciprocity, affecting 20+ nations like those listed. That adds another layer of difficulty for travelers trying to move through or out of high-risk areas.
What Americans inside Level 4 countries are told to do
For Americans already inside a Level 4 country, official advice is direct: leave immediately on commercial flights if possible. If departure is unsafe, they are told to shelter in place, monitor developments, stock supplies and keep in contact with family.
U.S. help may be sharply limited in those situations. In Somalia, there have been no evacuations since 2025.
The warning level can also carry financial effects before a trip even starts. Travelers are advised to check advisories 72 hours before departure and confirm whether insurance excludes Level 4 destinations.
The State Department also recommends enrollment in STEP, the Smart Traveler Enrollment Program, for alerts and aid prioritization. Country-specific embassy pages list contacts, and the State Department app sends push notifications.

Afghanistan and Iraq at the center of the warning system
Afghanistan and Iraq sit at the center of that warning system because both combine several of the department’s stated risk factors. In Afghanistan, the advisory covers unrest, crime, health, kidnapping, terrorism, wrongful detention and natural disasters. In Iraq, it covers unrest, kidnapping, terrorism and other risks.
Those warnings place both countries among destinations where the State Department says Americans should not go at all. For travelers weighing family visits, work trips or transit plans through the region, the message is blunt.
The list’s scope also shows how broad the Level 4 category has become. It covers war zones such as Ukraine and Syria, countries with fragmented authority such as Libya, places gripped by gang violence such as Haiti, and states where detention of foreigners remains a concern, including Russia and Iran.
In Venezuela, hopes for eased access after Maduro’s capture have faded amid persistent unrest. Venezuela remains under Level 4, with crime, wrongful detention, the absence of a U.S. embassy and visa hurdles all cited as risks.
Health emergencies also remain part of the advisory framework. Afghanistan, Burma (Myanmar), Mali, Somalia, South Sudan and Yemen all include health among their listed concerns.
For travelers looking elsewhere, lower-risk destinations fall under Level 1 or Level 2. Indonesia (Level 2), Dominican Republic (Level 2), Puerto Rico (Level 1) and South Africa (Level 2) are listed as alternatives where insurance remains valid and embassy support is available.
Still, the State Department’s highest warning leaves little room for interpretation. In places carrying Level 4: Do Not Travel, the department says the risks are too high and the U.S. government may not be able to reach or assist Americans caught in danger.
With 22 countries and regions now under that designation and a worldwide caution added on March 22, 2026, Americans considering trips to Afghanistan, Iraq or any other Level 4 destination face the same official message: do not go, and if you are already there, leave if you can.
