Fraudulent Naturalization and the Risk of Denaturalization: The Case of Zohran Mamdani
U.S. citizenship obtained through naturalization is widely considered permanent. But under certain legal circumstances, it can be revoked. That rarely used process—denaturalization—has been thrust into the spotlight following allegations against New York City mayoral candidate Zohran Mamdani.
Mamdani, a Democratic Socialist and current state assemblyman, became a naturalized U.S. citizen in 2018. In June 2025, Representative Andy Ogles publicly accused him of concealing ideological affiliations during the naturalization process—specifically, of expressing past support for the Holy Land Five, a group convicted in 2009 of funneling money to the terrorist organization Hamas. If proven, those omissions could place Mamdani’s citizenship in legal jeopardy.
The controversy raises a key legal question: Can a naturalized American lose their citizenship for lying about past political affiliations or ideological sympathies?
What Is Denaturalization?
Denaturalization is the legal process by which the U.S. government revokes someone’s citizenship. It is governed by 8 U.S.C. § 1451(a) and applies in cases where naturalization was either illegally procured or fraudulently obtained. Though rare, denaturalization has been used in cases involving war crimes, terrorism, and immigration fraud.
There are two primary legal grounds: illegal procurement and willful misrepresentation or concealment of material facts. The former applies when someone was not legally eligible to become a citizen at the time they were naturalized—typically due to criminal history, affiliations with hostile groups, or lack of “good moral character.” The latter applies when the applicant knowingly lied or withheld information that would have likely led to denial of citizenship.
Allegations Against Mamdani
Representative Ogles’s accusation centers on the claim that Mamdani failed to disclose prior ideological support for individuals or groups linked to terrorism. In a post on the social media platform X, Ogles wrote, “Bye bye, little muhammad! If you lied on your N-400 naturalization forms, you’re going home.” The message was accompanied by an illustration featuring Mamdani holding a book emblazoned with a communist symbol and the caption “Deport Zohran.”
The post referenced Mamdani’s alleged ideological support for the Holy Land Five—a group whose members were convicted of providing financial support to Hamas under the guise of charitable donations. Such an affiliation, if proven and if omitted from naturalization paperwork, could undermine the “good moral character” requirement that is central to the citizenship process.
While the rhetoric is politically charged, the legal threshold for denaturalization remains high. The government would need to prove that Mamdani willfully misrepresented or concealed material facts during his application process.
What Would the Process Look Like?
If federal authorities pursue the matter, it would begin with an investigation by agencies such as the Department of Justice, Department of Homeland Security, or Immigration and Customs Enforcement. If sufficient evidence is found, the government could file a civil denaturalization suit in federal court.
To succeed, the government must meet an unusually high standard of proof: “clear, convincing, and unequivocal evidence.” If a judge finds that the naturalization was obtained through fraud or illegality, the court can revoke citizenship and revert the individual to their previous immigration status—opening the door to potential deportation.
Legal Precedent
Historically, denaturalization has been applied in grave cases. Nazi collaborators who lied about their wartime activities were stripped of U.S. citizenship decades after the fact. More recently, individuals who concealed ties to ISIS or other terrorist organizations have faced the same fate.
The use of denaturalization remains rare and politically sensitive, but the legal precedent is well established: If citizenship was obtained through fraud, it can be undone.
What Happens Next?
As of now, the allegations against Mamdani are just that—allegations. No formal investigation or legal action has been announced. But the accusations, especially when amplified by federal lawmakers, could spur an inquiry.
Whether the government chooses to act will likely depend on whether credible evidence emerges that Mamdani knowingly omitted material affiliations or sympathies that would have disqualified him from citizenship.
Regardless of the outcome, the case reflects broader tensions in American politics around immigration, national security, and ideological litmus tests. As scrutiny of the naturalization process intensifies, so too does the debate over what it means to become—and remain—a U.S. citizen.

For more than a decade, the State of Qatar pursued a foreign policy centered on soft power projection, strategic ambiguity, and global influence. Despite being a small nation with a citizen population of fewer than 400,000, Qatar exerted outsized regional and international influence through a mix of media funding, financial sponsorships, and diplomacy that often involved supporting opposing sides in a conflict simultaneously.
Recent developments, however—including rising tensions with Iran and shifting U.S. strategic priorities—are exposing the limits of this model. Qatar’s political balancing act is losing viability, and the state now faces a narrowing set of options to preserve its security and relevance in the Middle East.
Qatar’s Strategy: Soft Power and Strategic Leverage
Qatar’s approach to power projection relied heavily on influence rather than military strength. It funded institutions across the West, including major universities such as Georgetown, think tanks, and non-governmental organizations. These investments gave Qatar visibility and input in Western policymaking circles.
Its media outlet, Al Jazeera, became one of the most influential voices in the Arab-speaking world and beyond. The network has played a major role in shaping regional narratives, including coverage critical of regional rivals like Saudi Arabia and Egypt, while at times platforming groups and figures aligned with Islamist movements, including Hamas.
Qatar has also hosted Hamas leadership in Doha and provided financial assistance to the Gaza Strip. While it has argued that this aid is humanitarian in nature, critics have contended that it amounts to indirect support for Hamas’s political and military operations, which many Western nations—including the U.S. and EU—designate as terrorist activities.
Playing Both Sides: Relations with Iran and Israel
Qatar has maintained cordial relations with Iran, despite broader regional hostility toward Tehran from other Gulf Cooperation Council (GCC) states. The two countries share ownership of the world’s largest natural gas field, which has encouraged Qatar to keep diplomatic channels open with the Islamic Republic.
At the same time, Qatar has cultivated ties with the United States, including hosting the Al Udeid Air Base, the largest American military installation in the Middle East. Qatar also hosts the Taliban's political office, further highlighting its positioning as a diplomatic middleman.
This balancing act extended to the Iran-Israel dynamic. Qatar publicly supported the Palestinian cause and gave platforms to anti-Israel voices, yet also kept informal economic and security channels open with Israel, often acting as an intermediary in negotiations related to Gaza ceasefires.
The Risks of Strategic Ambiguity
While Qatar’s “multi-vector” strategy initially gave it flexibility, it also created risks. Supporting groups like Hamas while maintaining U.S. and European alliances placed Qatar in a difficult position whenever regional escalations occurred. The October 2023 Hamas attack on Israel—combined with increased Iranian assertiveness—drew renewed scrutiny of Qatar’s role.
Privately, some reports suggest that even factions within Hamas and Iran have grown frustrated with Qatar’s approach, seeing it as opportunistic or unreliable. Iranian officials and affiliated commentators have issued increasingly critical statements accusing Qatar of hedging its bets rather than fully supporting its regional partners.
Meanwhile, Hamas-affiliated social media accounts reportedly mocked Qatari civilians fleeing missile threats—suggesting that Qatar’s financial backing has not necessarily bought enduring loyalty or influence within those groups.
The Decline of U.S. Military Presence and Loss of Leverage
Qatar’s strategic value to the United States has been partly rooted in its willingness to host U.S. forces. However, as the U.S. shifts its military and economic focus to the Indo-Pacific region and reduces its footprint in the Middle East, Qatar’s leverage with Washington may diminish. The potential downgrading or eventual relocation of operations at Al Udeid would further erode the country’s geopolitical clout.
At the same time, Qatar’s reliance on foreign military protection becomes more precarious if regional tensions escalate without clear backing from a major power. Without credible deterrence of its own, and with friction growing on multiple fronts, Doha faces a narrowing strategic corridor.
A Potential Pivot: Normalization with Israel
One of the few remaining options available to Qatar could involve a public and formal normalization of relations with Israel—akin to the agreements made under the Abraham Accords by the UAE, Bahrain, Morocco, and others.
Such a pivot would offer Qatar security benefits, particularly in countering threats from Iran or militant non-state actors. It could also open the door to deeper economic and technological cooperation. However, this would require a sharp reversal of many years of public messaging and ideological positioning—posing potential domestic and regional challenges.
Recent hostilities and the rise of Iranian missile threats might serve as a face-saving rationale for such a pivot. Qatar could frame normalization as a necessary security alignment rather than a shift in values. This is especially plausible if U.S. support continues to wane and Israel remains the dominant regional military power.
Conclusion: A Strategic Recalibration
Qatar’s foreign policy over the past two decades has been ambitious and multifaceted, but its underlying contradictions are catching up with it. Funding groups in conflict with one another, attempting to act as both broker and beneficiary, and depending on loyalty that was often transactional—these are not sustainable long-term strategies.
As regional dynamics evolve and traditional alliances become more fluid, Qatar may be forced into recalibrating its approach. Whether this results in formal ties with Israel, greater alignment with Western interests, or a retreat from regional activism remains to be seen.
What is increasingly clear, however, is that the era of Qatar as a dominant soft power influencer, immune from consequences, may be coming to a close.
