German citizens who wish to naturalize in the US require a so called Retention Permit to keep German citizenship (“Beibehaltungsgenehmigung”) in order not to lose their German citizenship through naturalization abroad (Sect. 17, 25 German citizenship law).
Since German language skills are one major requirement for this Retention Permit, please note that detailed information on the procedure, requirements, costs etc. are only available in German. Please click here to be forwarded to the German website.
