Types of Residence Permit

On arrival in Frankfurt, you usually will have to go to the local Foreigners' Office (Ausländerbehörde) to extend your visa/residence permit (Aufenthaltsgenehmigung) at some point during the first 3 months of your stay. In most cases it will be clear which of the residence title set out in the paragraphs of the Residence Act (Aufenthaltsgesetz) is most suitable for you. In some cases you will be able to choose the paragraph that will appear on your residence permit and this decision can have advantages and disadvantages depending on your particular situation. The following residence permits are generally available for researchers:


This paragraph is addressed mostly to students and can also apply to doctoral students who are registered for a PhD. In this case, the main purpose of the stay should be to attain a PhD.

§18b Abs. 1

This paragraph is aimed at those who are working and have an employment contract (e.g. research assistants/ wissenschaftlicher Mitarbeiter). It is also possible to choose this paragraph if you are pursuing a PhD alongside work.

§18c Abs. 3

This paragraph is addressed to highly qualified persons (so-called high flyers in the areas of economics, science and research). In certain circumstances, a permanent residence permit can be issued. The research institute must, among other, provide justification and disclose the selection criteria.

Scientific Visa - §18d-f

This paragraph is aimed at researchers who already have a research project. In this case, the research institute needs to have signed a hosting agreement.

BLUE CARD - §18b Abs. 2

The Blue Card is a residence permit.
The EU Blue Card serves to promote the mobility of researchers within Europe. This includes third-country nationals who will enter Germany directly from a third country, and those who are already in another EU member state under an EU Blue Card. However, it may also be worth considering for researchers who are already residing in Germany.
You need to meet certain criteria before the EU Blue Card can be issued. You require:

  • A German or a foreign university degree which is either recognised and acknowledged in Germany, or is comparable to a German degree.
  • An employment contract
  • A minimum salary (information about the amount can be attained at the Foreign Citizens' Office).

Generally if you are planing to come to Germany to study, obtain a doctoral degree or for the purpose of employment as an international scholar you are strongly advised not to enter Germany on a Schengen visa. This visa cannot be extended or changed to another purpose of stay, regardless of the original purpose it was issued for (e.g. tourist stay, visit or business trip). All internationals must leave the country after their Schengen visa expires!
