F 1 visa, there are two forms of legal work to earn money.

1. School jobs, libraries, school buses, school canteens, research assistants and other job opportunities in your school. There seems to be a limit of 20 hours a week.

2. Holiday CPT requires that the type of work is related to your major, the weekly limit is 40 hours, the school is single batch, and there are some specific academic requirements.

Except these two, everything else is illegal.

However, it's hard to say that the school found out that you were expelled from school, but I think the school has an obligation to report to the government after it finds out. At this point, it's a matter of expulsion ... not expulsion.
