If you are entering or transiting the UK, UK authorities will ask for an Electronic Travel Authorisation (ETA), a mandatory digital form to:

• Non-European citizens who don't need a visa will need an ETA to travel from 8 January 2025.

• European citizens will need an ETA to travel as from 2 April 2025.

We advise you to apply as far in advance as possible. To process the Electronic Travel Authorisation (ETA) and to get more information, please visit this page GOV.UK/electronictravelauthorisation.
