**Zohran Mamdani, the sitting New York City mayor elected in 2025, is a naturalized U.S. citizen since 2018 after immigrating from Uganda as a child.** Republican lawmakers raised denaturalization questions in 2025 over alleged nondisclosure of political associations on his application, prompting DOJ letters and public calls for investigation. Immigration law experts and fact-checkers have found no verifiable evidence of material misrepresentation or fraud that meets the high bar for revocation, which requires a judicial order rather than executive action. Denaturalization remains rare and procedurally demanding, with limited precedent for cases tied to political speech or associations absent clear proof of willful deception during the naturalization process. As of mid-2026, no active court proceeding or successful revocation has advanced despite the earlier political attention. Trader consensus at 97.6% against revocation before 2027 reflects these structural and evidentiary hurdles. Realistic scenarios that could still shift odds include emergence of new primary documentation proving deliberate falsehoods on the 2018 application, a sustained DOJ enforcement push leading to litigation that concludes rapidly, or an unforeseen Supreme Court ruling expanding denaturalization grounds—though all carry low probability given current records and timelines.
