Schengen Area
Definition
Schengen Area: The Schengen Area is a group of 29 European countries that have abolished routine internal border checks and share common rules for short-stay visitors, including the 90/180-day limit.
The Schengen Area and the European Union overlap but are not the same. As of 2026, Schengen includes most EU countries plus Iceland, Norway, Switzerland, and Liechtenstein; Bulgaria and Romania became full members in January 2025. Ireland and Cyprus are EU members outside Schengen, and the UK is in neither.
For US citizens, the most important rule is the 90/180-day limit: you can spend up to 90 days in any rolling 180-day period across all Schengen countries combined, not per country. Your passport should be valid for at least three months beyond your planned departure from the area and have been issued within the past 10 years.
Some Schengen countries periodically reinstate temporary internal border checks, so carry your passport when crossing between them. Our Schengen 90/180 rule guide shows how to count your days.
