These are the 20 most dangerous countries for US travelers in 2026, according to the US State Department
Belarus
Once part of the Soviet Union, Belarus maintains close ties with its neighbor, Russia. From Gothic architecture to rare near-endangered species, Belarus has attractions for castle seekers and nature enthusiasts.
In recent years, Belarus has allowed Russia to use some of its territory to invade Ukraine.
The risk of civil unrest makes visits to Belarus unwise, according to the State Department. The US Embassy suspended operations there in 2022.
Americans traveling to Belarus should exercise the usual precautions for visiting high-risk countries and consider leaving their phones, computers, and other electronic devices behind. The State Department also recommends not accessing social media accounts while in Belarus because they may be monitored.
Central African Republic
The Central African Republic touches several other level-four countries, including Sudan and South Sudan, and is home to an incredibly rich biodiversity in its national parks, including Dzanga-Sangha National Park and Manovo-Gounda St. Floris National Park.
Many of the country's species are endangered, and its citizens have faced decades of instability, according to the United Nations.
Recently, armed groups have targeted Muslims and refugees.
The US State Department considers CAR a dangerous travel destination due to threats of terrorism, crime, civil unrest, unexploded land mines, and kidnapping, as well as health concerns. US citizens can expect limited help from the US Embassy in Bangui, CAR's capital.
Due to the threat of kidnapping, the US' travel advisory website suggests travelers leave DNA samples with their doctor and establish proof-of-life protocols with family or friends so they can assist you if you're abducted. The State Department also suggests keeping a low profile, avoiding travel to rebel-controlled areas, and not resisting robbery attempts.
Niger
Visitors to the landlocked African country of Niger can explore the ancient mud-brick mosque of Grande Mosquée d'Agadez and the storied old town of Agadez, as well as see the Sahara Desert and the country's unique wildlife.
In October 2025, the US authorized that all government employees leave the country due to widespread safety concerns. Parts of the country have been under a state of emergency for over a decade, and local authorities "require military escorts for any foreigners" traveling outside the capital, Niamey, per the US State Department.
The agency warns of violent crime, civil unrest, terrorism, limited health services, and kidnapping throughout the country.
If they choose to visit anyway, US citizens are advised by the government to draft a will and have an emergency plan that doesn't depend on support from the US Embassy.
Ukraine
Much like Istanbul's Hagia Sofia, for which it was named, the Saint Sophia Cathedral serves as an eye-catching landmark in Kyiv. It's just one of the Ukrainian capital's architectural treasures.
Russia invaded Ukraine in 2022, and years of fighting have ensued, mainly in the east, where the border lies. Belarusian troops are also present along its border with Ukraine.
The ongoing conflict is the principal reason the US government cautions against visiting. Areas that aren't on the frontline of fighting could still experience drone and missile attacks, the State Department notes.
Drafting a will, coordinating a security plan, and creating a communication protocol with loved ones are just a few of the steps suggested on the travel advisory website.
