Can you keep your Tunisia citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Tunisian citizens who become U.S. citizens generally keep their Tunisian nationality, since Tunisian law allows dual nationality in most cases.
What the law says
- Tunisian law has allowed dual nationality in most cases since 1975.
- Dual nationality is forbidden for the President of Tunisia.
- Tunisian nationals may not renounce their nationality.
- The 2014 Constitution states no Tunisian can be deprived of their nationality.
- Naturalized persons may lose nationality for certain acts, such as failure to complete military service in Tunisia.

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 Tunisia lets you keep yours.
