Can you keep your Germany citizenship when you become a U.S. citizen?
Allowed
Yes, in general
German citizens who become U.S. citizens keep their German citizenship, as dual citizenship is now allowed without restrictions.
What the law says
- A 2024 nationality law reform removed the requirement to renounce German citizenship after acquisition of a foreign citizenship.
- The reform permits multiple nationality and removed previous requirements to renounce previous citizenships upon German naturalisation.
- Dual citizenship is generally possible.
- Dual citizenship is now allowed without restrictions.
“Dual citizenship is now allowed without restrictions.”
What about the U.S. side?
The United States allows dual citizenship. At the oath ceremony you promise to renounce allegiance to other countries, but U.S. law does not make you formally give up your other passport. The question is only whether Germany lets you keep yours.
