One way to finance your studies is to take a part-time job. Weimar is a small city, which means that finding a good student job isn’t easy. Many student job offers are posted on campus at the beginning of every semester – such as on the notice boards in the University Library and faculties. You can inquire directly at your faculty or ask your professor about possible job openings, or you can search for jobs on the Piazza.
For many students in Germany, it's quite normal to work part-time while studying. A part-time job can help students make career decisions, it's a welcome change from phases of intensive academic work, and it supplements incomes. As an international student, you are also allowed to work in Germany. However, certain rules do apply.
