Hi Ritara, you've given us almost no information to go off, but to answer your question there are no fixed salary ranges for L permits. I know people who earned 13k a month on L permits. There is a lower limit - i.e. if your employer is employing you for a full time job and paying lower than what is deemed to the minimum to survive then he may well be asked what the story is. This "poverty line" varies from place to place and is often mistaken for a minimum wage - Switzerland has no such thing.

But a maximum range for a given permit type? Absolutely no way. Surely this must be something you heard over a beer or two, but I doubt very much whether your employer would say such a thing.

Will a masters degree make a difference to your salary? Why should it? If I were an employer I wouldn't pay you extra for a degree unless it was directly relevant to the job you were doing.

If you are unhappy about your salary then I would suggest searching this forum for "salary" and "salaries" and doing a bit of reading, then posting specific questions about your situation on the relevant threads.
