Introduction

Swiss permits depend on your situation (contract, duration, family) and the applicable legal framework. It is not just “a card”.

  • L: usually associated with contracts/shorter stays.
  • B: temporary residence of several years; Be careful with changes in employer, activity or canton (as applicable).
  • C: more stable status after years; It changes the panorama of some procedures, but does not eliminate obligations.

How to avoid fines or conflicts

Checklist upon arrival:

  1. Registration in the commune.
  2. Medical insurance within the applicable period.

Practical Tips
