Detailed description
The residence permit for completing a qualification measure is a temporary residence permit. You can apply for an extension of the residence permit if the qualification measure(s) has/have not yet made up for the identified deficits in foreign qualifications, for example because you have to repeat an exam or the exams are preceded by long waiting times.
The same conditions apply to the extension of the residence permit to complete a qualification measure as for the granting of the permit. In particular, your livelihood must be secured for the entire duration of the qualification measure(s).
In the event of an extension, your residence permit will be limited again. The residence permit for the purpose of completing a qualification measure can be extended by six months. However, the total length of stay for the purpose of completing the qualification measures must not exceed two years.
As a rule, the residence permit cannot be extended if this was already excluded when the residence permit was issued or last extended.
