Residency in Switzerland
The precondition for permanent residency in Switzerland is a residence permit.
After the bilateral treaty on the free movement of persons for EU citizens entered into force on June 1, 2002 (the complete text can be found at www.admin.ch), different provisions apply to persons from EU/EFTA countries and persons from third countries.
As a rule it falls within the jurisdiction of the Cantonal Aliens Registration Offices to issue residence permits. Their addresses can be found at www.bfm.admin.ch.
