5. Prioritizing Denaturalization The Department of Justice may institute civil proceedings to revoke a person’s United States citizenship if an individual either “illegally procured” naturalization or procured naturalization by “concealment of a material fact or by willful misrepresentation.” 8 U.S.C. § 1451(a). The benefits of civil denaturalization include the government’s ability to revoke the citizenship of individuals who engaged in the commission of war crimes, extrajudicial killings, or other serious human rights abuses; to remove naturalized criminals, gang members, or, indeed, any individuals convicted of crimes who pose an ongoing threat to the United States; and to prevent convicted terrorists from returning to U.S. soil or traveling internationally on a U.S. passport. At a fundamental level, it also supports the overall integrity of the naturalization program by ensuring that those who unlawfully procured citizenship, including those who obtained it through fraud or concealment of material information, do not maintain the benefits of the unlawful procurement.
