Can you keep your Cambodia citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Cambodian citizens who become U.S. citizens generally keep their Cambodian citizenship, since dual nationality is permitted.
What the law says
- Dual nationality is permitted under Cambodian nationality law.
- Dual nationals may be viewed as Cambodian citizens in court proceedings.
- A 2021 constitutional amendment bans the prime minister and presidents of the National Assembly, Senate, and Constitutional Council from being citizens of other countries.
- Citizenship is typically acquired through ancestry (at least one Khmer parent) or naturalization.
“Dual nationality is permitted, although dual nationals may be viewed as Cambodian citizens in court proceedings.”
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 Cambodia lets you keep yours.
