Is there some sort of secret competition going on in this thread to see who can give the most wrong information in the most authoritative sounding way?
From an official page of the German Foreign Office at
http://www.auswaertiges-amt.de/www/e...e/faq/kat3/F10:
As well as German nationality, our child has had a second nationality since birth. Does our child have to choose between the two in later life?
No, as far as German law is concerned, if your child automatically had two nationalities at birth, he/she does not have to decide between the two at a later stage. Your child is therefore a permanent holder of dual nationality. In some cases, the law of the other country may however dictate a need to choose.
