The rules of travel to Europe will change starting from 2024, as anyone traveling to Europe from the United States will be required to have a travel authorization to enter most European countries through the European Travel Information and Authorization System (ETIAS). ETIAS is currently not in operation and no applications are being collected at this point.
ETIAS travel authorization is an entry requirement for visa-exempt nationals traveling to any of these 30 European countries. It is linked to a traveler’s passport and 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 ETIAS travel authorization.
With a valid ETIAS travel authorization, 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.
