Visa Information

A U.S. visa allows a foreign citizen to travel to a U.S. port of entry and request admission into the United States from a Department of Homeland Security, Customs and Border Protection immigration officer.

The Department of State recommends its Web site, http://travel.state.gov, as the primary source for visa information.

The State Department also recommends for information on how to contact any Embassy Consular Section Worldwide for additional procedures, including how to schedule an interview appointment, pay fees, and much more.

Applicants should apply to the U.S. Embassy or Consulate in his or her country of residence.
