I have a question here: what happens if you leave the employer who applied the Swiss Work Permit B for you? Can they take the B permit back? They will inform concerning department so you will be asked to leave the country?

Or, nothing will happen. You still hold the permit and looking for the next employer? Apply for approval of change of employer then start working?

Many thanks!

Depends what type of B Permit you have; Is it linked to your employer?

Thank you for your reply

I can change job with my permit. It is confirmed by population office.
