In U.S. federal immigration law, citizenship revocation usually means denaturalization—a legal action to revoke citizenship obtained through naturalization. Deportation, more commonly called removal in current proceedings, concerns whether a noncitizen may remain in the United States. They involve different people, grounds, and decision-makers; removal proceedings are not a way for an immigration judge to revoke citizenship.
At a glance: two different legal processes
| Question | Denaturalization (citizenship revocation) | Deportation or removal |
|---|---|---|
| Who is affected? | A naturalized U.S. citizen whose naturalization the government seeks to revoke. | A noncitizen in removal proceedings. |
| What is at stake? | Whether the naturalization order and certificate should be revoked. | Whether the person may remain in the United States, including whether relief or protection from removal applies. |
| Where is it handled? | In a civil action in federal district court under 8 U.S.C. § 1451. | In removal proceedings before an immigration judge, with review paths that depend on the case. |
| Does one automatically lead to the other? | No automatic result or sequence is established by the distinction between these proceedings. | An immigration judge cannot revoke naturalization; EOIR says immigration judges lack jurisdiction over that issue. |
What denaturalization means
Denaturalization is the legal process for seeking revocation of citizenship granted through naturalization. The Department of Justice identifies grounds that include illegally procuring naturalization, or procuring it by concealing a material fact or willfully misrepresenting one. The statute provides for an action in federal district court. DOJ’s Justice Manual guidance describes the department’s approach; its page reports an October 2024 update and an April 2025 notice that the guidance was being revised. The statutory framework appears in 8 U.S.C. § 1451.

This denaturalization process concerns naturalized citizenship. It should not be treated as the same process for people who acquired citizenship at birth. The cited denaturalization authorities address naturalization, not a general power to deport any U.S. citizen.

What deportation or removal means
“Deportation” remains the familiar term, while removal is the usual term for current U.S. proceedings. A removal case concerns a noncitizen’s right to stay and any relief or protection that may apply. It follows immigration grounds and procedures distinct from the grounds and court action involved in denaturalization. The EOIR policy manual explains immigration judges’ jurisdiction, including that they do not have jurisdiction to revoke naturalization.

A passport or citizenship document is not citizenship itself
Not every government action involving a citizenship document is denaturalization. The Department of State may revoke a passport or cancel a Consular Report of Birth Abroad (CRBA) in specified cases involving illegal, fraudulent, or erroneous issuance. Those document actions are separate from a court judgment revoking naturalization. USCIS discusses this distinction in its policy guidance on citizenship acquisition and related documents.

The label on a notice matters: a federal district-court denaturalization action and an immigration-court removal case are different proceedings. Their consequences and available responses depend on the individual facts, so the general distinction here cannot predict an outcome or the order in which separate proceedings might occur. For case-specific advice, consult an immigration attorney or a DOJ-accredited representative. USCIS explains who is authorized to provide immigration legal advice in its legal services guidance.
