Can international students work part-time and be self-employed in Germany?

As an international student, your work is restricted by your student residence permit. Generally, you're allowed to work 140 full days or 280 half days per year. However, being self-employed or working freelance is usually not automatically covered by this permit. You'll likely need a separate permit from the Foreigners' Office (Ausländerbehörde) for any self-employment. Always confirm the current limits and specific requirements for self-employment with your residence permit conditions and the Ausländerbehörde.
