From permit L through B and C to S status: an overview of which permit fits which life situation — and which transitions are realistic.
Swiss residence permits differ in duration, renewal rules, family reunification, employment and travel freedom. Being in the wrong category costs time, options and sometimes one's livelihood. They are regulated mainly by the Foreign Nationals and Integration Act (FNIA) and, for the protection categories, by the Asylum Act.
Valid for up to one year, exceptionally extendable to 24 months. Classically used for project-based activities, seasonal work and internships. Family reunification is generally excluded, with narrow exceptions for spouses.
The transition from L to B is possible but not guaranteed. The cantonal migration office reviews integration, employer needs and quotas. For third-country nationals these quotas are particularly tight.
