on Schengen Agreement
A total of 30 states, including all European Union states and three
non-EU members (Iceland, Norway, and Switzerland), are subject to
the Schengen rules, and 24 have implemented them so far.
The Republic of Ireland and the United Kingdom only take part
in the police co-operation measures and not the common border control
and visa provisions.
Border posts and checks have been removed between the states which
form the Schengen area. A common Schengen visa allows tourists or
other visitors access to the area.
Holders of residence permits to a Schengen state enjoy the freedom
of travel to other Schengen states for a period of up to three months.
