With the entry into force on 1 May 1999 of the Schengen Protocol of the Treaty of Amsterdam of 2 October 1997, Schengen cooperation was transposed into EU law, initially solely on the basis of an international agreement. The two Schengen agreements have been a major step forward for transport in Europe. Queues would often be one kilometre long and wait for border patrols to sign them, but the agreements helped to stop them. Today, people can enter neighbouring countries without having to present any form of identity card. Of course, airlines always require you to show it for security reasons, but border controls are much easier to navigate and don`t even exist in some cases. Now that the Schengen Agreement is part of the Community acquis, it has lost to the EU Member States the status of a treaty which could only be amended in accordance with its terms. Instead, changes are made in accordance with the EU`s legislative procedure under the EU treaties.  Ratification by the former signatory states is not necessary to amend or repeal all or part of the previous Schengen acquis.  Acts setting out the conditions for accession to the Schengen area are now adopted by a majority of the EU`s legislative bodies. The new EU Member States do not sign the Schengen Agreement as such, but are required to implement the Schengen rules within the framework of existing EU legislation, which any new entrant must accept. [Citation required] Originally, the Schengen treaties and the rules adopted between them were officially independent of the EEC and its successor, the European Union (EU). In 1999, the Treaty of Amsterdam incorporated them into EU law, which codified Schengen into EU law and also introduced opt-outs for Ireland and the Kingdom, the latter having taken place since its withdrawal from the EU. EU Member States that do not yet have an opt-out and have not yet joined the Schengen area are legally obliged to do so if they meet the technical requirements.
Although it is linked to EU legislation, several third countries are present in this region after signing the agreement. Although not a member of the EU, Switzerland, because of its position at the heart of Europe, maintains strong economic and social relations with many Schengen states and is part of the European Free Trade Association (EFTA) with Iceland, Norway and Liechtenstein (other third countries within the Schengen area). Switzerland became an integral part of the Schengen area after signing the agreement on 26 October 2004 and beginning to implement it on 12 December 2008. Indeed, the Schengen Agreement paved the way for the release of the Schengen visa. Although this is not part of the original provisions of the agreement, the top 15 countries need only a visa for all. The Schengen visa may allow non-EU members to travel freely to the countries participating in the programme. Differences of opinion between Member States led to a deadlock in the abolition of border controls within the Community, but in 1985 five of the ten Member States at the time – Belgium, France, Luxembourg, the Netherlands and West Germany – signed an agreement on the phasing out of border controls. The agreement was signed on the princess Marie-Astrid boat in Moselle, near the city of Schengen, where the territories of France, Germany and Luxembourg meet. Three of the signatories, Belgium, Luxembourg and the Netherlands, had already abolished common border controls under the Benelux Economic Union. [Citation required] In another case, the visa application resulting from the Schengen agreements corresponds to any visa procedure. You apply, send your passport and then receive a stamp if you are approved. However, they must meet certain criteria and requirements in order to qualify for a visa under the Schengen Agreement.
One of the most remarkable requirements is Schengen visa insurance. This situation means that Schengen Member States that were not part of the EU have few formally binding options to influence the development and development of the rules
