The visa policy of Ireland is set by the Government of Ireland and determines visa requirements for foreign citizens. If someone other than a European Union, EFTA or Common Travel Area citizen seeks entry to Ireland, they must be a national of a visa-exempt country or have a valid Irish visa issued by one of the Irish diplomatic missions around the world.
Although Ireland is a member of the European Union, it is not part of the Schengen Area and therefore sets its own visa policy. Ireland also operates the Common Travel Area with the United Kingdom, the Channel Islands and the Isle of Man which specifies open borders between the countries and territories. Established in 1923, it permits British and Irish citizens freedom of movement around the Common Travel Area and to cross its borders with minimal or no identity documents.
