Title 8 › Chapter CHAPTER 12— - IMMIGRATION AND NATIONALITY › Subchapter SUBCHAPTER III— - NATIONALITY AND NATURALIZATION › Part Part II— - Nationality Through Naturalization › § 1451
The law lets U.S. attorneys go to federal court to try to take away someone’s citizenship if they have proof the person got naturalized illegally, hid an important fact, or lied on purpose. The case is usually filed where the naturalized person lives. If the person lives nowhere in a U.S. district, the case can be in the District of Columbia or where they last lived. If the government sues, the person must get 60 days’ personal notice to answer, unless they say they don’t want it. If the person is absent from the U.S. or the district where they last lived, notice can be given in person or by published notice like other court rules. If within five years after a naturalization that was granted after December 24, 1952 the person joins or affiliates with a group that would have stopped them from becoming a citizen, that membership is treated as proof they lied or hid facts at the time of naturalization unless they show otherwise. Also, if within ten years after naturalization a person refuses to testify before a congressional committee about subversive acts and is convicted of contempt, that refusal can be a ground for revocation. If a court finds naturalization was illegally obtained or procured by concealment or willful misrepresentation, the revocation is treated as if it never took effect from the original date. A person who gained U.S. citizenship because a parent or spouse was naturalized loses that citizenship if the parent’s or spouse’s naturalization is revoked for concealment or willful misrepresentation, no matter where they live. If the parent’s or spouse’s naturalization is revoked for other listed reasons, the derivative citizen loses citizenship unless they are living in the United States at the time. A criminal conviction under federal law for illegally getting naturalization also requires the court to cancel the naturalization and certificate. When a court cancels naturalization, it must send a certified copy of the order to the Attorney General and the person must surrender their certificate when told to do so. This statute also covers older naturalizations granted by courts or the former Commissioner, and it does not stop the Attorney General from reopening or changing a naturalization order.
