I am Non EU national and is in Switzerland on B permit since last 4 years. I am resigning my Job in May and would like to just stay in Switzerland for additional 30 days. I have a valid B permit that expires in Nov 2010. Can I stay in Swiss after quitting the job ? Any info will be highly appreciated.

Just to add my B permit is B PERMIT (Ausländerausweis). I guess it is specific to company and project too.
