Citizens from some non-EU countries are required to hold a visa when travelling to the Schengen Area. The EU has a common list of countries whose citizens must have a visa when crossing the external borders and a list of countries whose citizens are exempt from that requirement. These lists are set out in Regulation (EU) 2018/1806. Generally, a short-stay visa issued by one of the Schengen States entitles its holder to travel throughout the 26 Schengen States for up to 90 days in any 180-day period. Visas for visits exceeding that period remain subject to national procedures.
