Frage
I will travel to Germany to set up my GmbH this week by holding a business VISA. Then I plan to apply a residence permit to local authority, when I set up my GmbH and apply a settlement permit after three years. It is my understanding there are a couple of considerations as individual assessment from local immigration office, when I apply a settlement permit following three years` residence permit. Moreover, I wonder if a German social security scheme (Health, pension, unemployment, nursing and accident) I should necessarily participate in during the three years before my applying a settlement permit. In another word, is the social security participation necessary for a permit switch from residence to settlement?
