Can you keep your Chile citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Chilean citizens who become U.S. citizens keep their Chilean citizenship, since Chile allows dual nationality.
What the law says
- Chile allows dual nationality under the new laws.
- From 2005, Chilean nationality did not depend on renouncing any other nationality.
- A 1957 constitutional change allowed dual nationality for Spanish nationals or where obtaining another nationality was not voluntary.
- Historically, nationality could be canceled if marriage to a foreigner automatically bestowed another nationality.
“Chile allows dual nationality under the new laws.”
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 Chile lets you keep yours.
