Can you keep your Guinea citizenship when you become a U.S. citizen?
Not allowed
No, in general
Guinean citizens who voluntarily acquire another nationality, such as U.S. citizenship, may lose their Guinean nationality.
What the law says
- Guineans of origin may lose their nationality for voluntarily acquiring another nationality.
- Dual nationality is not allowed in Guinea for persons who obtained Guinean nationality at birth.
- Guinean nationals can renounce their nationality pending approval by the state.
- Persons who previously had nationality and wish to repatriate after voluntarily losing it must establish residency and request reinstatement.

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 Guinea lets you keep yours.
