REVOCATION INFO

The controlling statute for revocation of citizenship or denaturalization is the Immigration and Nationality Act ("INA") § 340 [8 U.S.C. 1451] (1994). A U.S. citizen may lose his/her citizenship either voluntarily (renouncing citizenship) or involuntarily.

In sum, the grounds for involuntarily losing one's naturalized U.S. citizenship include:

Lying to the USCIS during the naturalization process

Service in the native country's Armed Forces (if said country is at war or engaged in hostilities with the United States)

Serving in the native country's Armed Forces as an officer or a non-commissioned officer

Holding an elected or policy-level position in the native country

Conviction for an act of treason against the United States

Refusal to testify before Congress about one's subversive activities
