Can you keep your Oman citizenship when you become a U.S. citizen?
Not allowed
No, in general
Omani citizens who become U.S. citizens generally do not keep Omani citizenship, since Oman does not allow dual citizenship except by Royal Decree.
What the law says
- Oman does not allow dual citizenship, except by the Royal Decree of the Sultan.
- Naturalization applicants must be willing to renounce foreign citizenship(s).
- Foreigners are rarely given citizenship.

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 Oman lets you keep yours.
