Denaturalization is the federal process of revoking citizenship from a naturalized U.S. citizen, but what are the grounds for denaturalization? The government cannot take this step merely because it dislikes something a citizen did after naturalization. It must establish a legal basis related to how you obtained citizenship or another reason authorized by federal law.
A threat of denaturalization demands your immediate attention. A civil complaint, subpoena, or government inquiry can trigger strict response deadlines, and missing one may limit your ability to challenge the allegations. Your regular immigration attorney may understand agency processes but lack the training or resources to defend a contested case in U.S. district court. Hillary Walsh is a denaturalization attorney who has that experienced.
Under 8 U.S.C. § 1451, the government may use illegal procurement as a reason to revoke your citizenship. Illegal procurement means that a person was not legally eligible for citizenship at the time they received it.
The allegation may involve a claim that you failed to satisfy a naturalization requirement, such as lawful admission for permanent residence or the required period of good moral character. In an illegal-procurement case, the government may argue that your citizenship was invalid even without proving an intentional lie. The defense therefore requires a careful review of the full immigration record and the law that applied when you naturalized.
The government may also claim that you obtained citizenship through concealment of a material fact or willful misrepresentation. A fact is material when truthful disclosure would have influenced the naturalization decision or led officials to investigate further.
These cases often depend on the wording of old applications and interview testimony from years earlier. An incomplete answer does not automatically prove deliberate fraud, so counsel must test whether the statement was actually false and whether the disputed fact mattered to eligibility. Federal law also identifies narrow conditions for denaturalization involving certain organizational affiliations after naturalization or a qualifying military discharge. These provisions are fact-specific and do not result in an automatic loss of citizenship.
Denaturalization is not a routine U.S. Citizenship and Immigration Services matter. The Department of Justice brings a civil case in federal court, where procedural rules and evidence standards applied to grounds for denaturalization shape the defense from the beginning.
