Do I need a passport or visa to enter?
U.S. citizens need a passport to enter Kosovo. No visa is required, but visitors may be asked to provide documentation stating the purpose of their visit. Generally, visitors entering Kosovo are permitted to stay for up to 90 days. Persons who wish to stay beyond 90 days will need to register with the Directorate for Migration and Foreigners in Pristina. If you intend to work, study, or remain longer than 90 days in Kosovo, you are required to contact the Directorate for Migration and Foreigners prior to your arrival in Kosovo to obtain information about requirements for visitors in these categories. The telephone numbers are (381) 38-200-190-26; (381) 38-200-190-27; (381) 38-200-190-17 or you can contact them by email. The Kosovo Ministry of Foreign Affairs website includes contact information for the Embassy of Kosovo in the United States, which can help you with additional information on how to apply for a residency permit.
The Law on Foreigners stipulates that a foreigner is obliged to present photo identification to prove his or her identity when asked by an authorized official. However, you do not have to carry an original passport with you at all times while in Kosovo.
Kosovo is an independent, sovereign country, but Serbia still considers it to be part of Serbia. As a consequence, Serbian border officials will prevent U.S. citizens from entering Serbia from Kosovo without first obtained a Serbian entry stamp from a Serbian point of entry that is not on the Kosovo-Serbia border. For example: if travelers enter Serbia from Belgrade airport, or neighboring Macedonia or Montenegro, and receive a Serbian entry stamp upon entry, they may travel through Serbia to Kosovo and then back into Serbia without difficulty; if they first enter Kosovo from a country other than Serbia, and then try to cross into Serbia from Kosovo, the Serbian authorities will not allow the traveler to enter Serbia. Serbia does not recognize entry stamps by Kosovar border authorities at Kosovar ports of entry, including Pristina Airport.
