The Electronic System for Travel Authorization (ESTA) is an automated system that determines the eligibility of visitors to travel to the United States under the Visa Waiver Program (VWP). This program allows citizens of participating countries to travel to the U.S. for tourism, business, transit, or medical purposes without needing a visa, for stays of 90 days or less. For example, a German citizen intending to attend a conference in New York for a week might utilize this system for authorization.
This system offers several advantages, including a streamlined application process and reduced processing times compared to applying for a traditional visa. Its implementation has significantly simplified short-term travel for eligible individuals. The development of the VWP and this authorization system reflects an effort to facilitate international exchange and commerce, while maintaining security measures. The eligibility is based on the citizenship of the traveller.
