The coming semester didn't start yet and didn't pay for it yet at my university in Beijing. But I got a good offer from a job, they want me to work on the student visa part-time or let them convert the student visa to a business F visa first and then later convert it to a Z-visa.

What's the best way for me to handle this issue? It seems there are so many people working on F student visa's, but never heard anybody got deported. Also will it be bad if I cancel my current university without paying the school fee and change the visa which the university issued to a F-visa?
