Your options:
You can come to Germany with a foreign university degree 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 university degree is equivalent to a German university degree. Therefore, you should contact the responsible German foreign mission in order to find out how to prove the equivalence of your university degree.
You can get more information about the procedure for assessing the equivalence of university degrees in the Recognition section.
