Summary

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.

Aliens and Nationality — Source: USLM XML via OLRC

(a)It shall be the duty of the United States attorneys for the respective districts, upon affidavit showing good cause therefor, to institute proceedings in any district court of the United States in the judicial district in which the naturalized citizen may reside at the time of bringing suit, for the purpose of revoking and setting aside the order admitting such person to citizenship and canceling the certificate of naturalization on the ground that such order and certificate of naturalization were illegally procured or were procured by concealment of a material fact or by willful misrepresentation, and such revocation and setting aside of the order admitting such person to citizenship and such canceling of certificate of naturalization shall be effective as of the original date of the order and certificate, respectively: Provided, That refusal on the part of a naturalized citizen within a period of ten years following his naturalization to testify as a witness in any proceeding before a congressional committee concerning his subversive activities, in a case where such person has been convicted of contempt for such refusal, shall be held to constitute a ground for revocation of such person’s naturalization under this subsection as having been procured by concealment of a material fact or by willful misrepresentation. If the naturalized citizen does not reside in any judicial district in the United States at the time of bringing such suit, the proceedings may be instituted in the United States District Court for the District of Columbia or in the United States district court in the judicial district in which such person last had his residence.
(b)The party to whom was granted the naturalization alleged to have been illegally procured or procured by concealment of a material fact or by willful misrepresentation shall, in any such proceedings under subsection (a) of this section, have sixty days’ personal notice, unless waived by such party, in which to make answers to the petition of the United States; and if such naturalized person be absent from the United States or from the judicial district in which such person last had his residence, such notice shall be given either by personal service upon him or by publication in the manner provided for the service of summons by publication or upon absentees by the laws of the State or the place where such suit is brought.
(c)If a person who shall have been naturalized after December 24, 1952 shall within five years next following such naturalization become a member of or affiliated with any organization, membership in or affiliation with which at the time of naturalization would have precluded such person from naturalization under the provisions of section 1424 of this title, it shall be considered prima facie evidence that such person was not attached to the principles of the Constitution of the United States and was not well disposed to the good order and happiness of the United States at the time of naturalization, and, in the absence of countervailing evidence, it shall be sufficient in the proper proceeding to authorize the revocation and setting aside of the order admitting such person to citizenship and the cancellation of the certificate of naturalization as having been obtained by concealment of a material fact or by willful misrepresentation, and such revocation and setting aside of the order admitting such person to citizenship and such canceling of certificate of naturalization shall be effective as of the original date of the order and certificate, respectively.
(d)Any person who claims United States citizenship through the naturalization of a parent or spouse in whose case there is a revocation and setting aside of the order admitting such parent or spouse to citizenship under the provisions of subsection (a) of this section on the ground that the order and certificate of naturalization were procured by concealment of a material fact or by willful misrepresentation shall be deemed to have lost and to lose his citizenship and any right or privilege of citizenship which he may have, now has, or may hereafter acquire under and by virtue of such naturalization of such parent or spouse, regardless of whether such person is residing within or without the United States at the time of the revocation and setting aside of the order admitting such parent or spouse to citizenship. Any person who claims United States citizenship through the naturalization of a parent or spouse in whose case there is a revocation and setting aside of the order admitting such parent or spouse to citizenship and the cancellation of the certificate of naturalization under the provisions of subsection (c) of this section, or under the provisions of section 1440(c) of this title on any ground other than that the order and certificate of naturalization were procured by concealment of a material fact or by willful misrepresentation, shall be deemed to have lost and to lose his citizenship and any right or privilege of citizenship which would have been enjoyed by such person had there not been a revocation and setting aside of the order admitting such parent or spouse to citizenship and the cancellation of the certificate of naturalization, unless such person is residing in the United States at the time of the revocation and setting aside of the order admitting such parent or spouse to citizenship and the cancellation of the certificate of naturalization.
(e)When a person shall be convicted under section 1425 of title 18 of knowingly procuring naturalization in violation of law, the court in which such conviction is had shall thereupon revoke, set aside, and declare void the final order admitting such person to citizenship, and shall declare the certificate of naturalization of such person to be canceled. Jurisdiction is conferred on the courts having jurisdiction of the trial of such offense to make such adjudication.
(f)Whenever an order admitting an alien to citizenship shall be revoked and set aside or a certificate of naturalization shall be canceled, or both, as provided in this section, the court in which such judgment or decree is rendered shall make an order canceling such certificate and shall send a certified copy of such order to the Attorney General. The clerk of court shall transmit a copy of such order and judgment to the Attorney General. A person holding a certificate of naturalization or citizenship which has been canceled as provided by this section shall upon notice by the court by which the decree of cancellation was made, or by the Attorney General, surrender the same to the Attorney General.
(g)The provisions of this section shall apply not only to any naturalization granted and to certificates of naturalization and citizenship issued under the provisions of this subchapter, but to any naturalization heretofore granted by any court, and to all certificates of naturalization and citizenship which may have been issued heretofore by any court or by the Commissioner based upon naturalization granted by any court, or by a designated representative of the Commissioner under the provisions of section 702 of the Nationality Act of 1940, as amended, or by such designated representative under any other act.
(h)Nothing contained in this section shall be regarded as limiting, denying, or restricting the power of the Attorney General to correct, reopen, alter, modify, or vacate an order naturalizing the person.
