ETIAS

ETIAS is the upcoming electronic travel authorization system of the European Union. Applying for ETIAS will be mandatory for short stays within the Schengen area for travelers from visa-exempt third countries. With a valid ETIAS travel authorization, you can visit these 30 European countries. However, the issuance of an ETIAS authorization does not guarantee entry. Upon arrival, a border officer will check your passport and other documents to determine whether you meet all entry requirements.

At this time, applying for ETIAS is neither possible nor necessary.
