While Bulgaria and Romania, which joined the EU on 1 January 2007, are also legally obliged to join the Schengen area, implementation has been delayed. On 15 October 2010, Bulgaria and Romania joined SIS II for law enforcement cooperation.  On 9 June 2011, the Council of Ministers concluded that the evaluation process had been completed and that both countries met all technical criteria for accession.  Bulgaria and Romania`s applications for entry into the Schengen area were approved by the European Parliament in June 2011, but were rejected by the Council of Ministers in September 2011, as the Dutch and Finnish governments expressed concern about shortcomings in the fight against corruption and the fight against organised crime.   Although the original plan was for the Schengen area to open its air and sea borders with Bulgaria and Romania by March 2012 and its land borders until July 2012, persistent opposition from Germany, Finland and the Netherlands delayed the entry of the two countries into the Schengen area.   On 4 October 2017, the European Parliament voted in favour of Bulgaria and Romania`s access to the Schengen information system.  On 1 August 2018, Bulgaria and Romania gained unlimited access to the Schengen information system.  In addition, „the final political decision to be part of the Schengen area and to put an end to systematic border controls with eu neighbouring countries must be taken unanimously by all parties to the European Council.“  On 11 December 2018, the European Parliament voted in favour of the resolution on the adoption of the two countries, which calls on the Council of the European Union to „act quickly“.   Once a visitor has entered the area, a visitor may travel without severe borders or additional passport controls. As part of the Schengen area, tourists can travel with Hungarian Hungarian etias and to any other Schengen country. The French overseas departments of Guyana, Guadeloupe, Martinique, Mayotte and Reunion as well as the Overseas Community of Saint Martin are part of the European Union, but are not part of the Schengen area, which means that it is not possible to travel to these departments on a French Schengen visa. The EU`s free movement provisions apply, but each territory has its own visa regime for non-Swiss, non-Swiss.
While a valid visa for one of these territories is valid for all, visa waiver lists differ.  A Schengen visa, also issued by France, is not valid for these territories. A visa for Sint Maarten (valid for traveling on the Dutch side of the island of Saint Martin) also applies to the French page.  France also has several territories that are not part of the EU or the Schengen area.  They are located there: French Polynesia, South and French Antarctica, New Caledonia, Saint Barthélemy, Saint-Pierre-et-Miquelon and Wallis and Futuna. Around 1.7 million people cross a European border to work every day, and in some regions they account for up to a third of the labour force. For example, 2.1% of Hungarian workers work in another country, mainly in Austria and Slovakia. Every year, there are a total of 1.3 billion border crossings at the Schengen borders. 57 million crossings are needed for the transport of goods by road worth 2.8 trillion euros per year.    Goods trade is more affected than trade in services and the decline in trade costs ranges from 0.42% to 1.59% depending on geography, trading partners and other factors.  While Ireland first submitted a request for participation in the Schengen acquis in 2002, which was approved by the Council of the European Union, this decision has not yet entered into force.
