Residence Permit ("Aufenthaltstitel")
Citizens from the European Union (EU) and the European Economic Area (EAA) do not need a residence permit. EAA citizens include those from Iceland, Liechtenstein and Norway.
Citizens from all other regions must apply for a residence permit ("Aufenthaltstitel") at the Foreigners’ Office (“Ausländerbehörde“) if the research residency in Germany is planned for more than 90 days.
Since there is considerable processing time, this must be done well in advance before your current visa expires OR within 90 days upon arrival if no visa was required for entry into Germany.
The residence permit you will get depends on the main purpose of your stay. So if the purpose of your stay changes, you will need to book a new appointment at the Foreigners’ Office.
Your city of residence determines which Foreigners’ Office you should go to. You will therefore need to book a new appointment for example, if you move from Potsdam to Berlin and vice versa.
A residence permit usually has an expiration date - please remember to apply for an extension (if applicable) well before your current permit expires.
The validity of your residence permit cannot exceed the validity of your passport. Please renew your passport in time (if necessary) before your appointment.
