Your problem would not be on the US side, it would be on the German side. Unless you specifically renounce it, the US won't take your citizenship away except perhaps in an egregious case of treason, so it de facto, although usually not de jure, tolerates dual citizenship. Germany, as the above link probably shows, expressly forbids it unless it would be an extreme hardship to renounce your initial citizenship, which is not the case for US citizens. As far as someone getting around the German requirement to renounce your US citizenship in the event of naturalization as a German, I would like to know how that was achieved. The only circumstance that I am aware of in which you could keep your original US citizenship is if you were naturalized by Germany as the descendant of a person whose German citizenship was revoked for political reasons by the Nazis BEFORE that former German ancestor acquired the citizenship of another country. This primarily applies to the descendants of German Jews.
There are plenty of ways to reside in Germany without German citizenship. I doubt that dual citzenship will be allowed anytime soon here because there is little or no constituency for the idea of people as a ressource here, instead they are de facto usually viewed as a burden. I think that the reasons for this is that about 40% of the economy is goods exports, and that the social system will be under strain for the foreseeable future.
Yo, completely agree, and then the Germans shake their heads saying that foreign nationals (like the Turks) don't integrate, it's no wonder you're not wanted.
It's the race theory, if you're parents aren't German you're not German simple as. I thought about citizenship many years ago, but now that I'm allowed to (after min. 8 years of residency) wouldn't dream of renouncing my passport to have a German one. This is the whole slant in this country and if you're born in a country you should at least be able to have dual citizenship, but that's not allowed either!
