Hello,
I'm a Blue Card holder and been living in Berlin with my wife for a year now. I have to go back to my home country and probably stay there for a couple of years due to personal issues. I understand that my Blue Card will get voided but in the future, we want to come back and live in Germany again.
A couple of questions:
1- What are the steps I should take before leaving Germany? I heard there is a de-registeration process
2- Knowing that we want to be back in the future, what should be taken into consideration?
3- Is there a way to ask German Foreign Office to not void the Blue Card and hold it for 2-3 years?
Thank you in advance.
