There is no date yet for Cyprus, which joined the EU in 2004, nor for Bulgaria and Romania (accession in 2007) or for Croatia (accession in 2013). A Schengen visa or visa exemption does not allow the traveller to enter the Schengen area, but allows the traveller to apply for entry to the crossing point. The Schengen border code lists the requirements that third-country nationals must meet in order to enter the Schengen area. To this end, a national of a third country is a person who does not enjoy the right to free movement (i.e. a person who is not an EU national, of the EEA, Switzerland or the United Kingdom, or a family member of a person in possession of a residence card marked „family member of a European Union citizen“ or „family member of an EEA or CH citizen“). The rules for short-term entry visas into the Schengen area are set by EU regulations, which contain two lists: a list of nationalities (or categories of holders of travel documents) that require a short-stay visa (the List of Schedule I) and a list that does not (the list list in Appendix II).  The Schengen Regulation on the Crossing of Internal Borders describes the checks carried out by the police in appropriate locations within each country. [Clarification needed] In order to remedy the potentially aggravating effects of the removal of border controls on undocumented immigration and cross-border crime, the Schengen acquis provides for police and judicial compensation measures.  One of the most important is the Schengen Information System (SIS), , a database managed by all EU and Schengen Member States, which contained more than 30 million entries by January 2010 and more than 50 million entries by January 2014, according to a document published by the Council of the European Union in June 2015.  About 1 million entries concern people, 72% of whom have not been allowed to enter and stay in the Schengen area. Only 7% of those listed in the SIS database were missing persons. From 2015[update], Andorra, Monaco and San Marino negotiated an association agreement with the EU.
Andorra`s ambassador to Spain, Jaume Gaytén, said he hoped the agreement would include provisions that would make states associated with the Schengen agreement.  Participating countries are required to strictly control travellers entering the Schengen area. These controls are coordinated by the European Union`s Frontex agency and are subject to common rules. The details of border controls, surveillance and the conditions under which entry into the Schengen area can be granted are described in detail in the Schengen border code.   An application for a Schengen visa should be submitted to the embassy or consulate of the country the traveller intends to visit.
