ETIAS is an entry requirement for visa-exempt travelers visiting many European countries.
Once active, ETIAS will be electronically linked to your passport and generally valid for up to three years (or until your passport expires, whichever comes first). It will allow short stays of up to 90 days within any 180-day period, but it does not guarantee entry, as border officials make the final decision upon arrival.
