Working as a mechanical engineer in Germany

Anerkennung is the process of having a foreign degree formally recognised in Germany, and it is mandatory only for regulated professions. For a Blue Card application it is enough to show that the degree is "comparable". These three are frequently confused:

Comparability (anabin)

The normal route for the Blue Card. Two separate checks are needed in the KMK anabin database: the university must be listed with H+ status (H+/− brings additional conditions, H− is not accepted), and the degree itself must be listed under that university. Most Turkish state universities are listed; foundation and newer universities vary — check rather than assume.

Zeugnisbewertung (ZAB)

The fallback route if the degree is not in anabin. It costs €208 (€104 for a second copy) and takes up to three months once the documents are complete. The most common cause of delay is starting this step too late.

Anerkennung (actual recognition)

Only for regulated professions: doctors, dentists, pharmacists, nurses, vets and teachers. Neither anabin nor ZAB replaces it.

A Turkish mechanical or electrical engineer can be hired in Germany and do engineering work. Titles such as "Development Engineer" or "Konstrukteur" are no problem. The one thing not allowed without a permit is calling yourself "Ingenieur" or "Dipl.-Ing."; breaching this is an administrative offence.

The title permit is governed by state law

"Beratender Ingenieur" — independent consulting engineer — is a separate licence.

The Blue Card is a work and residence permit for people with a university degree and a job offer above a set salary threshold. For 2026 the standard threshold is €50,700 and the threshold for shortage occupations and career starters is €45,934.20 gross a year.

Federal Employment Agency approval required. At the lower threshold the employment contract must run for at least six months. The Federal Employment Agency also carries out a comparability check: pay and working conditions may not be worse than those of a local employee.

Someone who graduated within the last three years qualifies for the lower threshold even if their profession is not on the shortage list.

Residence law sets no specific German requirement for the Blue Card itself. German enters indirectly in two places: permanent residence (after twenty-seven months with A1, twenty-one months with B1) and, in regulated professions, the language requirement set by the licensing authority.

§18g(1) sentence 2 no. 1 AufenthG defines shortage occupations by reference to ISCO-08 groups: 132, 133, 134, 21, 221, 222, 225, 226, 23 and 25. Among these, 21 covers natural scientists, mathematicians, engineers and architects; 221 doctors; 222 academic nursing and midwifery; 23 teachers; and 25 IT professionals — software developers, systems analysts, web developers, database administrators, systems administrators and network specialists.
