Bulgaria is currently being assessed for the Visa Waiver Program for entry in the near future
Bulgarian citizens are not eligible to apply for an ESTA (Electronic System for Travel Authorization) visa waiver to travel to the United States, however, this may change.
Thus, Bulgarian citizens will need to obtain a visa to travel to the United States for tourism, business, transit or any other travel purposes. For more information on applying for a U.S. visa, Bulgarian citizens can visit: https://usa-visas.com
The United States government continually evaluates the economic and political environment of a Visa Waiver Program member country. Possible member countries are assessed for their overall domestic stability as well as the likelihood that citizens of a member country would abuse the Visa Waiver Program. The significance of these considerations is that they ensure a visa waiver applicant's home country is not facing political or economic turmoil, and thus the traveler would be less likely to violate the rules of the program.
