Can you keep your Indonesia citizenship when you become a U.S. citizen?
Not allowed
No, in general
Indonesian citizens who become U.S. citizens generally do not keep their Indonesian citizenship, since dual nationality is not typically allowed and naturalized applicants must renounce other nationality.
What the law says
- Dual nationality is not typically allowed in Indonesia.
- Ordinary naturalization in Indonesia requires the applicant to renounce other nationality.
- Foreign spouses choosing Indonesian nationality must renounce their nationality of origin or obtain a permit to stay with dual nationality.
- Children may retain dual nationality until legal majority (seventeen), and must choose a single nationality after age twenty-one.
- Persons may be denaturalized for refusing to renounce other nationality when there is an opportunity to do so.
“Dual nationality is not typically allowed in Indonesia.”
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 Indonesia lets you keep yours.
