International Information
A United States passport is required for U.S. citizens who are not also Bulgarian nationals. As of September 1, 2006, U.S. citizens who enter the country without a Bulgarian visa are authorized to stay for a total of 90 days within a six-month period. This law is strictly enforced. An application to extend one's stay beyond the original 90 days can be filed for urgent or humanitarian reasons, but must be submitted to regional police authorities no later than five days prior to the end of the original 90-day period. Travelers who have been in the country for 90 days, and then leave, will not be able to reenter Bulgaria before the six-month period expires.
