Passengers travelling to the United States who are exempt from visa requirements need to apply for a travel authorisation.
Find out how the exemption programme works, how to proceed and where you can request exemption.
We warn you that without this authorisation (or visa), entry to the country is not permitted.
Due to the change in the travel requirements to enter the United States, as of November 8, 2021, ESTA’s, under the United Stated VISA Waive program, issued prior to the mentioned date may have been cancelled by the CDC. Please check that the status of your ESTA is still valid or if you will have to Create a New Application to travel. Confirm or request ESTA here and see full entry requirements here.
Electronic System for Travel Authorization (ESTA)
If you have a passport from one of these countries which was issued after 2001, you must use the Electronic System for Travel Authorization to apply for an electronic authorisation whenever you travel to the United States of America.
To obtain it just go the website and complete the form. This process must be carried out at least three days prior to travel. However, and to prevent any setbacks, you can request this authorisation before booking the trip.
Since 20 March 2010, airlines that allow passengers to travel to the USA without authorisation are also penalised.
TAP reserves the right, as of that date, to refuse to allow passengers to board until they have completed the necessary formalities.
- Go to the Electronic System for Travel Authorization website and enter the basic identification.
- When your travel has been authorised, print the document and keep it with your passport. You must show it on request when leaving Portugal or at US border control.
- If the system replies “Travel not authorised”, you will have to apply for a non-immigrant visa at the nearest US consulate or the US Embassy in Lisbon.
- If the system replies "Pending authorisation" you must return to the website 72 hours later to get the final answer.
- These authorisations are valid for 2 years from the date they are obtained and for multiple entries into the USA. If your passport expires, you must request a new authorisation.
