At the moment I have a German Blue Card after finishing my Msc in Germany, valid till the expiry date of my Passport (05.2021), the problem is that after the expiry of my passport I will not be able to renew it before my 30s birthday in 09.2021 cuz the embassy will not renew it for me before I reach 30 and get the final exemption from the military service. Meaning that there will be a gap of approx 4 months for me without a national passport. What can I do in these 4 months to be able to live and work legally in Germany? Will the Auslanderbehorde just give me a notification of deportation or they will cooperate and maybe issue me something temporary till I sort out my a new passport?
I do not care about my ability to travel in these months but I just want to keep my job and live and work legally. Any help or maybe guidance for what can be done?
