Passport and Visas:
U.S. Citizens must have a valid U.S. passport and Afghan visa to enter and exit.
You cannot obtain a visa upon arrival at Kabul International Airport.
Travelers arriving without a valid visa are subjected to deportation or confiscation of their passport and heavy fines.
Dual Nationals/Afghan Heritage:
U.S. citizens born in Afghanistan of Afghan parents are considered to be Afghan nationals and are not required to have an entry visa.
For U.S. citizens of Afghan parentage, but not born in Afghanistan, an entry permit is required. You should contact the Embassy of Afghanistan for more information. In addition, U.S. lawful permanent residents of Afghan heritage without Afghan passports should also contact the Embassy of Afghanistan to see what entry documents are appropriate.
U.S. citizens may enter and depart Afghanistan via military air carriers with their military ID card. Members of the U.S. military who entered Afghanistan on their military ID card should depart the country on military air carriers because they will have considerable difficulty departing Afghanistan on commercial airlines since their U.S. passports will not have an Afghan visa and/or an entry cachet recording their arrival.
Anyone arriving on military air should move quickly to legitimize their immigration status if there is any chance of departing Afghanistan on a commercial air carrier.
Travelers are expected to register with a representative of the Ministry of Interior’s Foreigners’ Registration Office upon arrival at Kabul International Airport.
If the airport office is closed, you should register at the Ministry of Interior’s Statistics Office in Kabul, located at Kart-e-Parwan Square in front of Nadirya High School, and bring two passport-size photos.
Upon registration, the traveler will be issued a card that he or she should surrender upon departure.
Immigration authorities in Afghanistan have also implemented a fingerprinting system for all foreign visitors, with the exception of U.S. government personnel traveling on official passports.
The U.S. Department of State is unaware of any HIV/AIDS entry restrictions for visitors or foreign residents of Afghanistan.
