How to immigrate to Germany after the German legal person visa is approved?

The approval of the German enterprise visa means that the German government recognizes the applicant's business plan for the next three years. As long as the plan in the business plan is implemented or basically implemented and the German level reaches B 1, you can apply for permanent residence in Germany.

You can refer to Article 2 1 of the German Residence Law: the company has been operating normally for three years on the basis of compliance with the law, and at the same time, corporate visa holders can apply for a German "green card", that is, permanent residence in Germany.

Let me explain here: "You can apply for permanent residence in Germany only after you have obtained residence for five consecutive years and paid social security for 60 months". This is a universal permanent residence law, and there are special laws for legal person visas to change to permanent residence in Germany.
