Machine-Readable Passports
All VWP travelers, regardless of age or type of passport used, must present a machine-readable passport. In addition, depending on when VWP travelers' passports were issued, other passport requirements may apply.
Residents of Canada, Mexico and Bermuda
Canada, Mexico and Bermuda are not participants in the Visa Waiver Program. The Western Hemisphere Travel Initiative (WHTI) requires all travelers to and from the Americas, the Caribbean and Bermuda to have a passport or other accepted document that establishes the bearer's identity and nationality to enter or re-enter the United States. Visit the Department of Homeland Security's Crossing Boarders website for more information about proper documentation.
