U.S. Citizenship and Immigration Services (USCIS), working with the Department of Justice (DOJ), has supported denaturalization actions against 10 naturalized U.S. citizens accused of obtaining citizenship through fraud or by concealing serious criminal conduct. Under the Immigration and Nationality Act, naturalized citizenship may be revoked if it was obtained unlawfully or through material misrepresentations. According to DHS, the cases involve individuals accused or convicted of offenses including child sexual abuse, healthcare and wire fraud, immigration fraud, identity fraud, and large-scale drug trafficking, with allegations that they lied during the naturalization process or concealed crimes that would have disqualified them from establishing the required good moral character. The DOJ has filed civil complaints in federal district courts seeking to revoke the citizenship of these individuals, alleging they either committed disqualifying crimes before becoming U.S. citizens or intentionally withheld critical information from USCIS during their naturalization applications and interviews. USCIS and DOJ emphasize that U.S. citizenship obtained through fraud is subject to revocation under federal law. The government notes that these are civil denaturalization proceedings, and the allegations contained in the complaints have not yet been proven in court or resulted in final determinations of liability.
