Electronic System for Travel Authorization for international travelers seeking to travel to the United States under the Visa Waiver Program (VWP)

The Electronic System for Travel Authorization (ESTA) is a United States government requirement (mandated by the Implementing Recommendations of the 9/11 Commission Act of 2007) for participating travelers from Visa Waiver Program (VWP) countries. The ESTA is required for travelers from participating countries arriving by air or sea, and replaces the old I-94W form.
