The Schengen Agreement, which came into force in March 1995, substantially relaxed border controls between France, Germany, Portugal, Spain and the Benelux countries. It has since been extended to apply to Denmark, Finland, Sweden, Austria, Greece and Italy. Persons moving directly between Schengen states will not normally be subject to border controls. There are normally no border controls between the UK and the Republic of Ireland, and citizens of these two countries need not carry passports or identity documents. Citizens of other EU countries have to carry a passport or national identity card. Persons from outside the EU also need to carry a passport and are supposed to report to border officials (if they can find them).
