    To see if your country is on the Visa Waiver Program list please go to this website: U.S. Department of State website.

    Under the VWP program, you are required to fill out an Electronic System for Travel Authorization (ESTA) application (for a minimal fee), and will automatically be enrolled in the Department of Homeland Security's US-VISIT program. While this can be done a few days prior to your trip, we advise it be done as soon as possible in case you are denied online approval.

    If you meet all criteria for Visa Waiver and your ESTA is approved, you do not need to visit a US consulate or embassy before your trip. All visitors traveling under the Visa Waiver Program MUST present machine-readable passports at their port of entry into the United States.
