Visa
the Schengen Visa may be the best-known example of a common visa. This visa has it origins in the 1985 Schengen Agreement among European states which allows for a common policy on the temporary entry of persons (including visas). The visa allows a tourist or visitor access to the area covered by the agreement (known as the “Schengen area” or “Schengenland”). Citizens of non-EU, non-EEA countries who wish to visit Europe as tourists, and who require a visa to enter the Schengen area, are simply required to get only the common Schengen Visa from the Embassy/Consulate of any of the Schengen countries. After this, they may visit any or all of the Schengen countries as tourists or for business without hindrance. They are not required to get separate visas for all the Schengen countries they wish to visit.
