General information

A citizen of a foreign country who seeks to travel to the United States generally must first obtain a U.S. visa. Visas are placed in the traveler’s passport, a travel document issued by the traveler’s country of citizenship.

Certain international travelers may be eligible to travel to the United States without a visa if they meet the requirements for visa-free travel. The visa section of this website contains information on U.S. visas for foreign citizens seeking to travel to the United States.
