Dual citizenship by country

Can you keep your Chad citizenship when you become a U.S. citizen?

Allowed

Yes, in general

Chadian citizens who become U.S. citizens keep their Chadian citizenship, since dual nationality has been allowed in Chad since 1962.

What the law says

“Dual nationality has been allowed in Chad since 1962”

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 Chad lets you keep yours.
