Mobility arrangements for international researchers:

International researchers from non-EU member states legally residing in EU Member States may conduct research in Germany. In such cases, two options allow you to stay in Germany:

• No residence permit for short-term research stays required: If you already hold a residence title from another EU Member State for research purposes and wish to stay in Germany for a maximum of 180 days within 360 days as part of a research project, you do not need to apply for a German visa or residence permit. The research institute in Germany must inform the Federal Office for Migration and Refugees (BAMF) about the planned research.
• Residence permit for mobile researchers: Planning a research stay lasting longer than 180 days but no more than a year? You'll need a residence permit for mobile researchers under Section 18f of the Residence Act (AufenthG). Requirements include holding a valid residence title of another EU Member State for research purposes, a valid passport or travel document, and a concluded hosting agreement or contract with a research facility in Germany. Apply for the residence permit at the local foreigners authority at least 30 days before starting your stay in Germany, or submit the application to the Federal Office for Migration and Refugees (BAMF).
