Electronic System for Travel Authorization (ESTA)
The Electronic System for Travel Authorization (ESTA) is an online pre-screening process required for travelers from Visa Waiver Program countries before entering the United States. It assesses eligibility and potential security risks by collecting personal, travel, and health information. Approved ESTA authorization allows travelers to board a flight or ship to the U.S. for up to 90 days without a visa. The system helps enhance security and streamline entry procedures, but it is not a visa and does not guarantee entry. Travelers must carry valid travel documents and may still be subject to inspection upon arrival.
