Can you keep your Mozambique citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Mozambican citizens who become U.S. citizens generally keep their Mozambican nationality, since Mozambique has allowed dual nationality in most cases since 2004.
What the law says
- Mozambique has allowed dual nationality in most cases since 2004.
- The main restriction on dual nationality is that the president must hold only Mozambican nationality.
- Mozambicans may renounce their nationality, provided they will not become stateless.
- The nationality law requires denaturalization for native citizens who perform actions, like voting, as if they were nationals of another country or for crimes against the state, but the 2004 Constitution makes no provisions for denaturalization.

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 Mozambique lets you keep yours.
