The USA does not recognize dual citizenship. 

I hope this answers your Q:Instructions

1Jus Sanguinis:
Jus Sanguinis refers to obtaining citizenship through descent of a child's parents. If you have German parents then, by German law, you are automatically considered a German Citizen. The same holds true for children born of American parents (by law, the child automatically obtains American Citizenship upon birth).

Children descended from one American parent and a German one obtain dual American/German citizenship upon birth.

2Jus Soli:
Jus Soli refers to obtaining citizenship through your place of birth. With a few exceptions, a person who is born in either the US or Germany obtains citizenship in that country. A few of these exceptions are:

* Children born to foreign government officials on assignment to the U.S.
* Those born in Germany to non-German parents before February 2, 1990

3Other than these two methods, there are no other ways to obtain dual German/US citizenship. Germany only recognizes one nationality so to obtain German citizenship through naturalization would require you to renounce US Citizenship. Likewise, you must renounce your German citizenship during the process of obtaining US Citizenship through naturalization.
