The most basic translation: send us official proof of your German citizenship.


But the same advice still stands. The Houston Consulate should be able to translate or provide advice on meeting whatever requirements need to be met. I'd be less concerned about the translation and more concerned about what will meet the expectations of the Standesamt.

Notarized with a raised seal -- geschickt bei post -- i.e. in the mail; -- oder gefaxed --(yeah, that's gut Deutsch)

If your friend is trying to claim or establish German citizenship and can't speak German or readily find someone who can, it's going to be an uphill struggle. The Germans are not particularly fond of foreigners who just want to come to Germany and soak up all the benefits (that's the perception). Having all the documents in order the first time will make it easier.
