thank you for reaching out to the Wefugees community.
As a student with §16 Aufenthaltsgesetz, you can work either 120 full days or 240 half days.
In addition, you can practice part-time work at the university. (may be as a Research Assistant). If you want to work more than 120 full days, you need a permission from the Immigration Service (Ausländerbehörde).
