What role does the State Department play in revocation of U.S. citizenship for dual nationals?
Executive summary
The State Department does not itself initiate denaturalization of U.S. citizens; revocation of citizenship for naturalized (dual-national) Americans is a judicial process that is typically handled by the Department of Justice after referral from immigration agencies, with records and notification involving State and other agencies [1] [2]. Law and practice separate voluntary renunciation (done at consulates or with State Department officers abroad) from court-ordered denaturalization, which is litigated in federal court and pursued by DOJ [3] [1].
1. Who actually strips citizenship: courts, not consulates
Revocation of naturalization—often called denaturalization—is a judicial act: federal courts cancel a person’s certificate of naturalization after civil or criminal proceedings brought by the Department of Justice, not by the State Department’s diplomats or consular officers [1] [2]. The DOJ’s Civil Division, or U.S. Attorneys, file those cases in federal district court; the State Department’s role is not to prosecute or file revocation suits [1] [4].
2. Where the State Department does have clear authority: renunciation abroad
The State Department directly handles voluntary renunciation of U.S. citizenship for people abroad: formal renunciation is done before a consular or diplomatic officer at a U.S. embassy or consulate, and that is a distinct, voluntary process separate from denaturalization litigation [3]. Available sources do not mention the State Department initiating involuntary revocation for dual nationals; they treat renunciation and denaturalization as different tracks [3] [1].
3. State Department’s administrative tasks after a court order
When a court revokes naturalization, USCIS updates records and notifies the Department of State; the State Department thus becomes involved administratively—receiving notice of cancellation and updating passports and consular records—but it is acting on the court’s order rather than deciding the revocation itself [2]. That administrative flow matters practically: loss of citizenship is effective as of the original naturalization date and agencies must reconcile passports, travel documents and nationality records [2].
4. Grounds and legal limits: what triggers DOJ action, not State diplomacy
Statute and agency guidance make clear that revocation is limited to specific grounds—most commonly that naturalization was procured illegally by concealment or willful misrepresentation, or certain post-naturalization affiliations within statutorily defined windows—and those are the bases DOJ pursues in court [5] [6] [7]. The State Department does not reframe or expand those grounds; its role is not to decide eligibility or evidence for denaturalization [6] [5].
5. Political pressure, DOJ priorities, and where State sits in the machinery
Recent policy shifts show the executive branch can prioritize denaturalization: a June 11, 2025 DOJ memo directed Civil Division attorneys to prioritize denaturalization cases, and reporting shows the department intends to target certain alleged crimes or fraud—an enforcement posture that originates at DOJ rather than State [1] [8] [9]. The State Department may echo administration messaging on citizenship as a policy matter, but it does not convert that into unilateral revocation authority [4] [9].
6. Constitutional and practical constraints the State Department cannot bypass
Supreme Court doctrine and statutory procedures limit how easily citizenship can be stripped; practitioners and scholars emphasize the heavy legal protections and the high evidentiary bar the government must meet in court—constraints that the State Department cannot override even if the executive branch shifts priorities [10] [11]. The State Department’s administrative updates and consular renunciation processes operate within those legal guardrails [3] [2].
7. Consequences for dual nationals and family members—an interagency outcome
If a naturalized person’s citizenship is revoked, the practical consequences rip across agencies: the individual returns to prior immigration status, USCIS updates files, DOJ secures the court result, and State is notified to cancel passports or citizenship records; derived citizenship for spouses or children can also be lost in specific statutory scenarios tied to the grounds of revocation [2] [5]. The State Department is therefore part of the downstream administrative and consular consequences, not the upstream legal decision-making [2] [5].
Limitations and contested views: reporting and legal commentary show two competing dynamics—an expansion of DOJ enforcement priorities in 2025 [1] [8] and longstanding judicial limits cautioning against easy political use of denaturalization [10] [11]. Available sources do not mention any authority allowing the State Department to unilaterally revoke a dual national’s citizenship outside the narrow voluntary-renunciation process administered at consulates [3] [4].
