Are Blue Card holders in Germany allowed to start a business besides their work as an employee?
I'm a non-EU engineer, with a blue card, working fulltime in a company in Germany.
I want to cofound a GmbH or mini-GmbH (UG) to work on my own project in my free time.
Assuming that my current employer will let me have my own business in my free time, Do you think the immigration office will also let me do this thing? What do I need to do in order to get the required permission?
P.S. My work permit is only for working in the current company. There is nothing mentioned about letting me be the director manager of a company.
