What is a esta?

Also called US travel authorisation

ESTA (Electronic System for Travel Authorization) is an online pre-approval that citizens of Visa Waiver Program countries need to visit the United States for short stays without a visa. You apply online before you fly, and approval is linked to your passport.

Eligibility, fees, and validity depend on your nationality and can change — always apply through the official government site and confirm the current requirements before you travel.
