Studying in Switzerland as an international student also means you can work up to 15 hours a week part-time during term time and full-time in university holidays.
If you are working towards a Ph.D. in Switzerland, you can also work part-time for up to 15 hours, but you don’t need to be in Switzerland for six months to start.
Employers need to organize a student visa work permit for you, and you need to continue being a full-time student and make sufficient progress on your program.
