As a non-EU student in Germany, can I work remotely for a foreign company?

As a non-EU student on a student visa, you have a limited number of days you're allowed to work per year (typically a full-day/half-day quota applies). However, working remotely from Germany for a company located outside the country can have complex implications for your taxes, social security, and residence permit. For freelance activities, you usually need separate permission from the foreigners' office (Ausländerbehörde). You should always verify the current rules for your specific situation with the relevant Ausländerbehörde and official sources.
