ESTA-clearance for visa waiver nationals travelling to the USA

Page latest updated:

Electronic System for Travel Authorisation (ESTA) is an automated system used by US Customs and Border Protection to determine the eligibility of visitors to travel to the United States under the Visa Waiver Program (VWP) and to assess whether such travel poses any law enforcement or security risk.

ESTA is mandatory for all nationals of VWP countries who plan to travel to the USA for temporary business or pleasure under the Visa Waiver Program (VWP). VWP travellers are required to receive an electronic travel authorization through ESTA prior to travelling to the USA. Accompanied and unaccompanied children, regardless of age, are required to obtain an independent ESTA approval.

A third party, such as a relative or travel agent, is permitted to submit an ESTA application on behalf of a VWP traveller.

U.S. CBP recommends that ESTA applications be submitted no less than 72 hours prior to travel. Later submission is possible but the approval may not be received in time for travel. An approved ESTA application is valid for a period of two years or until the applicant’s passport expires, whichever comes first. The visitor may travel to the United States repeatedly within a two-year period without having to apply for another ESTA.

Travellers who have not received ESTA approval are denied boarding.

Individuals who possess a valid visa will still be able to travel to the United States on that visa for the purpose it was issued. Individuals travelling on valid visas will not be required to apply for an ESTA.

In order to apply for an ESTA authorization, go to, follow the instructions to answer all the required questions, and submit an application for a travel authorization.

If an ESTA application is denied and the traveller wishes to continue with the trip, the traveller will be required to apply for a non-immigrant visa at a U.S. Embassy or Consulate. For more about visa application procedures, please visit
