As of December 2011, the Schengen Area consists of the following EU States: Belgium, Czech Republic, Denmark, Germany, Estonia, Greece, Spain, France, Italy, Latvia, Lithuania, Luxembourg, Hungary,
The free movement of persons is a fundamental right guaranteed by the EU to its citizens. It entitles every EU citizen to travel, work and live in any EU country without special formalities. Schengen cooperation enhances this freedom by enabling citizens to cross internal borders without being subjected to border checks. The border-free Schengen Area guarantees free movement to more than 400 million EU citizens, as well as to many non-EU nationals, businessmen, tourists or other persons legally present on the EU territory.
Originally, the concept of free movement was to enable the European working population to freely travel and settle in any EU State, but it fell short of abolishing border controls within the Union. A break-through came in 1985 when cooperation between individual governments led to the signing, in Schengen (a small village in Luxembourg), of the Agreement on the gradual abolition of checks at common borders, followed by the signing in 1990 of the Convention implementing that Agreement. The implementation of the Schengen Agreements started in 1995, initially involving seven EU States. Born as an intergovernmental initiative, the developments brought about by the Schengen Agreements have now been incorporated into the body of rules governing the EU. Today, the Schengen Area encompasses most EU States, except for Bulgaria, Croatia, Cyprus, Ireland, Romania and the United Kingdom. However, Bulgaria and Romania are currently in the process of joining the Schengen Area. Of non-EU States, Iceland, Norway, Switzerland and Liechtenstein have joined the Schengen Area.
Any person, irrespective of nationality, may cross the internal borders without being subjected to border checks. However, the competent national authorities can carry out police checks also at the internal borders and in border areas, provided that such checks are not equivalent to border checks. This is valid for cases when, in particular, the checks do not have border control as an objective and are based on general police information and experience. It's also valid when the checks are carried out in a manner clearly distinct from systematic border checks and on the basis of spot-checks. Under such circumstances, the police may for example ask you to identify yourself or pose questions regarding your stay, depending on the purpose of the check.
If there is a serious threat to public policy or internal security, a Schengen country may exceptionally temporarily reintroduce border control at its internal borders for, in principle, a limited period of no more than thirty days. If such controls are reintroduced, the other Schengen countries, the European Parliament and the Commission should be informed, as should the public.
More information on checks at internal borders can be found in the judgments of the Court of Justice of the European Union, concerning cases C-188/10 (Melki) and C-278/12 (Adil), as well as in the Commission's reports COM (2010) 554 on internal borders, COM (2012) 230 on the functioning of the Schengen area and COM (2013) 326 on the functioning of the Schengen area.
The Schengen provisions abolish checks at the Union's internal borders, while tightening controls at the external borders, in accordance with a single set of rules. These rules cover several areas:
Joining the Schengen Area is not merely a political decision. Countries must also fulfil a list of pre-conditions, such as be prepared and have the capacity to:
Applicant countries undergo a "Schengen evaluation" before joining the Schengen Area and periodically thereafter to ensure the correct application of the legislation.
