Can you keep your Hungary citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Hungarian citizens who become U.S. citizens keep their Hungarian citizenship, since dual citizenship is permitted under Hungarian law.
What the law says
- Dual citizenship is permitted under Hungarian law.
- It is not possible for a person to lose Hungarian citizenship involuntarily.
- The only exception concerns fraudulent applications for naturalisation, subject to a 20-year time bar.
- Hungarian citizens who hold another nationality and live outside Hungary may renounce their Hungarian citizenship.
“Dual citizenship is permitted under Hungarian law.”
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 Hungary lets you keep yours.
