Your options:

You can come to Germany with a foreign vocational qualification even if you do not have a binding job offer yet. The visa for jobseekers is a good solution for this.

When applying for a visa, you must prove that your foreign professional qualification is equivalent to a German one. This means that you need to apply for a recognition procedure with the competent authority in Germany.

You can get more information about the recognition of foreign qualifications in the Recognition section.
