Before first entering Germany, most non-EU citizens need to apply for a visa, while EU citizens can enter on their national ID card. Organize your visa application well ahead and make sure you apply for the correct type of visa from the very start, if you are planning to stay for longer than 3 months.
For the essential information on this topic for incoming researchers, such as who needs a visa (and who does not) and which type of visa to apply for, please read the corresponding section of our Welcome Guide and please do not hesitate to contact us.
