If you provided ESTA with your email when you applied, you will receive an expiration notice when your ESTA is about to expire. The email will advise recipients to go to the web site to reapply. See sample notice below:
The Travel Authorization to the United States for Jane Roe with passport number XXXX has expired.
If you have renewed your passport, you can renew your Travel Authorization for an additional 2 years, using our automated system which will allow you to obtain your new Atuhorization in aprox. one minute, by clicking Here.
Remember to print your new Travel Authorization and have it with you at the airport.
If you already renewed your ESTA with a new passport please ignore this message.
Your approved ESTA is valid for multiple entries into the U.S. over a two-year period. Exceptions to this validity period include applicants whose passports will expire before the two year validity period is complete - in which case the ESTA approval is only granted until the expiration date of the Passport.
