The Federal Ministry of
Education and Research has created the website Anerkennung in
Deutschland  (Recognition in Germany) with all necessary
information on this topic. You will find information on how to
recognize your foreign professional and vocational qualifications in
Germany. They differ four steps within the procedure : Advice,
Finding the competent authority, Submitting your application and
Receiving your assessment notice.
Depending on the occupation, recognition of your qualifications might either be a prerequisite or just helpful for applications.
In regulated professions such as doctor, lawyer or engineer recognition is a precondition. You can check the status of your profession by using the database  on regulated professions by the European commission.
