All travellers entering and leaving the Schengen area by general aviation or on a pleasure boat must find their first access/arrival point at an airport/airfield or seaport designated as a border crossing point at the external border. By exception, travellers on board a pleasure boat are allowed to make their first port of call in a port that is not designated as an external border crossing when informing port authorities and having the permission of the border guards.  In practice, however, this is a difficult loophole to control and large-scale drug trafficking involving private vessels has been discovered. Along the southern coast of Schengen countries in the Mediterranean, the coastguard is making considerable efforts to prevent the illegal entry of private boats. Permissions are issued for a validity period of one to five years and allow you to stay in the border area for up to three months. Permissions may only be granted to legitimate residents of the border area who have been in the border area for at least one year (or more if provided for in the bilateral agreement). Applicants must prove that they have legitimate reasons for frequently crossing a land border under the local border transportation system. Schengen states must maintain a central register of authorisations issued and allow other Schengen states immediate access to relevant data. 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.  The European Parliament and Council Directive 2004/38/EC of 29 April 2004 EU citizens and their family members have the right to move and stay freely within the territory of the Member States defines the right of citizens of the European Economic Area (EEA) to which the European Union (EU) and the three members of the European Free Trade Association (EFTA) Iceland, Norway and Liechtenstein belong. Switzerland, which is a member of EFTA but not of the EEA, is not bound by the directive, but has a separate bilateral agreement on free movement with the EU. In the 1940s and 1950s, Ireland had bilateral exemption agreements with Western European countries. The Schengen Agreement was signed on 14 June 1985 by five of the ten EC Member States in the Schengen City, Luxembourg. The Schengen area was created separately from the European Communities, when not all the Member States of the Eu reached a consensus on the abolition of border controls. The United Kingdom and Ireland participated in certain aspects of the Schengen Agreement from 2000 and 2002, such as the Schengen Information System (SIS). A short-stay visa costs 60 euros (46 USD; 66 USD) but only 35 euros for Russians, Ukrainians and citizens of some other countries, as part of the facilitation of issuing visas. The call was triggered by the announcement of a new electronic border regime in the UK, designed to enhance security by monitoring travellers entering the country, which will come into force in 2009.
