I used to study in Germany and currently graduated. According to law I have the right to work/reside for 18 months afterwards in Germany.
When I was leaving the country I deregistered (Abmeldung) from the city that I was residing in, but now it is only three months from my deregistration. In Buergeramt I have been told that since I have deregistered I cannot ask for prolonged stay in Germany anymore.
Since the woman I was talking too, seems to discriminate her clients. I was wondering whether there is part of the law that states that after de-registration one cannot extend his/her residence permit?
