Learn more about ESTA! The Electronic System for Travel Authorization (ESTA) is an automated system that assists in determining eligibility to travel to the United States under the Visa Waiver Program (VWP) and whether such travel poses any law enforcement or security risk. Upon completion of an ESTA application, a traveler is notified of their eligibility to travel to the United States under the VWP.
