It’s not that difficult to obtain official permission to live and work in Germany if you’re a skilled non-EU citizen with a job offer from a local company.
In general, there is no so-called “visa sponsorship” in Germany. If a company is ready to offer a candidate a job contract, he/she can apply for the work permit. It is, actually, much faster and easier to receive a work permit in Germany compared to other developed countries.
Once you’ve got a job offer from a German employer, you can immediately start preparing documents for visa and work permit.
