The enlargement of Schengen did not begin until a few months later with the signing of the agreement by Italy, followed by Spain and Portugal. Liechtenstein was the last country to sign in February 2008. This means that Schengen Member States that were not part of the EU have few formally binding options to influence the development and development of Schengen rules; their options are effectively reduced to approval or exit from the agreement. However, consultations are being held with the countries concerned prior to the adoption of certain new provisions. [14] Since June 2017[Update], ten urban transport agreements have come into force. The original Schengen area was formed in June 1985, when five European countries signed an agreement in a small town called Schengen in Luxembourg, aboard the princess Marie-Astrid ship in Moselle. Schengen is located on the border with Germany and France. Before reaching an agreement with a neighbouring country, the Schengen State must obtain the authorisation of the European Commission, which must certify that the draft agreement complies with the regulation. The agreement can only be concluded if the neighbouring EEA state and the Swiss on the Schengen side of the border area at least grant reciprocal rights and accept the repatriation of those who have abused the border agreement. The Belgian, French, German, Luxembourg and Dutch government signed the Schengen Agreement on 14 June 1985.
Under the agreement, the five countries would phase out common border controls. The ETIAS travel authorization allows access to all countries entering the Schengen agreement, i.e. the ETIAS and Schengen countries are identical, and a ETIAS authorisation is practically a Schengen visa. At many external border crossing points, there are special routes for EU, EEA and Swiss citizens (as well as family members) and other routes for all travellers, regardless of nationality. [217] At some border crossing points at the external border, there is a third route for Schedule II travellers (i.e. third-country/EEA/Swiss nationals who are exempt from the visa requirement). [218] Although Andorran and San Marines citizens are not EU or EEA citizens, they may use special routes for EU, EEA and Swiss citizens. [219] British citizens will not be able to use the EU`s trace after Brexit under current rules, unless such a right is introduced into the Brexit deal with the EU.
