The ETIAS (European Travel Information And Authorisation System) will not be operational until spring 2025.
ETIAS travel authorisation is an entry requirement for visa-exempt nationals travelling to any of these 30 European countries. It is linked to a traveller’s passport. It is valid for up to three years or until the passport expires, whichever comes first. If you get a new passport, you need to get a new travel authorisation.
With a valid travel authorisation, you can enter the territory of these European countries as often as you want for short-term stays – normally for up to 90 days in any 180-day period. However, it does not guarantee entry. When you arrive, a border guard will ask to see your passport and other documents and verify that you meet the entry conditions.
