Schengen Area

The Schengen Area /ˈʃɛŋən/ is the area comprising 26 European countries that have abolished passport and any other type of border control at their common borders, also referred to as internal borders. It mostly functions as a single country for international travel purposes, with a common visa policy. The Area is named after the Schengen Agreement. Countries in the Schengen Area have eliminated border controls with the other Schengen members and strengthened border controls with non-Schengen states.

Twenty-two of the twenty-eight European Union (EU) member states participate in the Schengen Area. Of the six EU members that do not form part of the Schengen Area, four – Bulgaria, Croatia, Cyprus and Romania – are legally obliged and wish to join the area, while the other two – Ireland and the United Kingdom – maintain opt-outs. All four European Free Trade Association (EFTA) member states – Iceland, Liechtenstein, Norway and Switzerland – have signed agreements on association with the Schengen Agreement, even though they are outside the EU. In addition, three European microstates – Monaco, San Marino and the Vatican City – can be considered de facto participants.
