Esta < Mobile PREMIUM >

: Once approved, an ESTA is generally valid for two years or until your passport expires, whichever comes first.

: Applications should be submitted through the official U.S. Customs and Border Protection (CBP) website or the official ESTA Mobile App to avoid third-party fees and potential fraud.

: It is highly recommended to apply at least 72 hours before departure. Real-time approvals are no longer guaranteed, and arriving at the airport without an approved ESTA will likely result in being denied boarding.

: You can travel to the U.S. multiple times during the validity period without needing to reapply each time.

: While you don't need to print the authorization (it is electronically linked to your passport), keeping a copy of your application number is useful for checking status or updating travel details.

: If your ESTA is denied, you must apply for a non-immigrant visa at a U.S. Embassy or Consulate.
