Procedures for Entering the United States

When you arrive in the United States, you must show valid travel documents as part of the entry process. The documents you need depend on the country you are arriving from and your citizenship or status.

Arrival from Canada, Mexico, and Bermuda

The Western Hemisphere Travel Initiative covers travel by land, sea, or air from Canada, Mexico, and Bermuda:

• American citizens entering the U.S. must show a valid passport, U.S. passport card, Trusted Traveler Program card (NEXUS, SENTRI, Global Entry or FAST), or an enhanced driver’s license. If you have any questions, contact your carrier to find out if they require a specific document.
• Lawful permanent residents of the U.S. need to show a Permanent Resident Card (Green card). A passport is not required.
• Citizens of Canada, Mexico and Bermuda can find the necessary travel documents from the Department of Homeland Security under “land and sea entry.”

Arrival from Other Countries

• All travelers entering the United States from all other countries need a passport upon arrival (regardless of their country of citizenship).
• Permanent residents and foreign nationals may also need a U.S. visa.  You must apply for a visa before you start your trip.
