United States visa policy permits citizens of Canada and Bermuda to travel to the U.S. without a visa.
The Visa Waiver Program (VWP) allows citizens of participating countries to travel to the US without a visa for 90 days. Currently, 37 countries participate in the VWP. To travel, you must have authorization through ESTA prior to boarding. ESTA is the automated web-based system to determine eligibility to travel without a visa to the US. Visit the ESTA page.
All other visitors to the US require a non-immigrant visa. For more information visit the Visas page.
If you need a visa, please start the process as soon as possible, as wait times are unpredictable.
