What documents do I need to extend my residence permit in Germany?

The documents required to extend your residence permit depend on the type of permit you have and your personal situation. Generally, you'll need your passport, a current registration certificate (Meldebescheinigung), proof of financial means (like a blocked account or scholarship), health insurance, and any additional documents relevant to the purpose of your stay (e.g., enrollment certificate for students). Before you apply, you should always check the most up-to-date list of required documents on the website of your local Ausländerbehörde (Foreigners' Office).
