Visa information

The Visa Waiver Program (VWP) allows citizens of participating countries to travel to the United States without a visa for stays of 90 days or less, when they meet all requirements. Travelers must be eligible to use the VWP and have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel.

In order to travel without a visa on the Visa Waiver Program, you must have authorization through the Electronic System for Travel Authorization (ESTA) prior to boarding a U.S. bound air or sea carrier. ESTA is the Department of Homeland Security (DHS), Customs and Border Protection's (CBP) automated web-based system to determine eligibility to travel without a visa to the United States for tourism or business. Visit the ESTA webpage on the CBP website for more detailed information, to apply for ESTA, and pay the fee.
