Getting Started with Your U.S. Visa Application
A citizen of a foreign country who seeks to enter the United States must often first obtain a U.S. visa. Visas are issued by U.S. consulates or embassies outside the U.S. Generally, the visa is provided in the form of a stamp in the traveler’s passport.
U.S. customs officials check your visa before granting entry at any port of entry, airport, and land border crossing. Your visa indicates that you are eligible for entry to the U.S. in a specific immigration category (e.g., F-1, J-1, H-1B, O-1).
Most (but not all) visas allow for multiple entries. The valid length of a visa varies based on the reciprocal agreement between the U.S. and the traveler's home country.
