What is the difference between residence permit B and residence permit C?

The B permit is a renewable authorization for temporary residence and work, with a duration of up to 5 years. The C permit is the residence permit, which represents a permanent authorization and is normally granted after 10 years of continuous residence (5 years for EU/EFTA citizens). Those who have a B permit can apply for a C permit once they have reached the required residence time and maintained the requirements of economic and social stability.

It is advisable to submit your renewal request at least 3 months before the expiry date of your current B permit. Report to the St. Gallen Migration Office with all the necessary documentation (updated employment contract, proof of accommodation, health insurance). If you submit the request in good time, the permit remains valid until the decision even if the technical expiry date has already passed.

What documents are essential to obtain the B permit?

The main documents are: valid passport or ID, employment relationship certificate, rental agreement or proof of accommodation, criminal record extract (from country of origin, translated and certified), proof of health insurance (LAMal), and federal application forms (available from the SEM).
