Visa Information
A United States of America (U.S.) entry Visa is required for all foreigners wishing to visit the U.S. except for most Canadian citizens and many citizens from Visa Waiver Program countries. Visa waiver travelers from ALL 27 Visa Waiver Program countries must present a machine-readable passport with a digital photograph at the U.S. port of entry to enter the U.S without a Visa; otherwise a U.S. Visa is required.
Please note that travelers covered by the Visa Waiver Program will still need to apply for an Electronic System for Travel Authorization (ESTA). This can be done online:
