Section 19a of the Residence Act determines the Blue Card´s requirements. The Blue Card is granted for the purpose of exertion of an occupation that requires highly qualified skills. The applicant is holder of a university level degree, that either has been issued by a German university or is acknowledged as an equivalent to such.
The most important requirement for the issue of an EU Blue Card is a degree from a German or foreign university. If the university degree was not obtained in Germany, it must either be recognised or comparable to a German university degree. Information on the equivalence and recognition of foreign university degrees can be found at www.anerkennung-in-deutschland.de. You can check the comparability of the university and the degree on the following page: https://anabin.kmk.org/anabin.html. We will be happy to support you in such assessment procedures.
As a second requirement, the applicant must submit a concrete employment contract or a binding job offer. The minimum gross annual amount is 55,200 € (4,600 monthly) from 01.01.2020. A reduced minimum annual gross salary of 43.056 € Euros applies to employment in the occupational fields of mathematics, computer science, the natural sciences, engineering and human medicine (not including dentistry) . The employment must be appropriate to the qualification (university degree).
If you live outside the EU, you will generally require a visa for the purpose of gainful employment which will be issued by the competent German diplomatic mission. You can enter Germany on this visa. Prior to expiry of the visa, you must subsequently apply to the local immigration authority for the EU Blue Card.
