Is an ESTA required for VWP travel to the U.S. via land borders?
ESTA will only be required for visitors traveling under the VWP to the United States via air or sea carriers. Travelers applying for admission to the United States under the VWP at land border ports of entry will continue to be processed as they are today. Neither Canada nor Mexico are VWP member countries, and so ESTA does not apply to Canadian or Mexican nationals’ travel. This page was last reviewed/modified on June 3, 2008.
