Can you keep your Mauritius citizenship when you become a U.S. citizen?
Allowed with conditions
Only in some cases
Mauritians of origin keep their Mauritian citizenship when they become U.S. citizens, but naturalised Mauritians do not.
What the law says
- Dual nationality is typically allowed in Mauritius for persons of origin since 1995.
- Dual nationality is prohibited for naturalised persons.
- Changes made in 1995 allowed Mauritians of origin, but not naturalised Mauritians, to have dual nationality.
- Mauritian nationals can renounce their nationality pending approval by the state.
“Changes made in 1995 allowed Mauritians of origin, but not naturalised Mauritians, to have dual nationality.”
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 Mauritius lets you keep yours.
