I have a residence permit (not a blue card) of Germany until January 2018, and the Rathaus has given me a Fiktionsbescheinigung until May 2018, waiting for me to submit a new contract.
Now I have a new contract in Finland and I need to work there from February, but because of school, I will move my family only after July 2018. Is it possible to keep the family in Germany and work in Finland? Will the Rathaus allow keeping the family in Germany until then?
