Dual citizenship is at the center of a new legislative fight.
Dual citizenship legislation would force many Americans to choose one nationality.
Why the senator wants to end dual citizenship
Republican senator from Ohio, Bernie Moreno, introduced the Exclusive Citizenship Act of 2025 with the intent to eliminate dual citizenship across the United States.
Moreno argues that U.S. citizenship should require “sole and exclusive allegiance.” He stated that when he naturalized, he renounced his Colombian citizenship, and he believes everyone else should do the same.
Supporters of the bill claim dual citizenship can cause “conflicts of interest and divided loyalties.”
They worry that Americans who hold foreign passports may feel obligations to other nations, obligations that could clash with U.S. interests. This bill matters because U.S. law currently allows dual nationality without requiring renunciation.
What the proposed law would do
If the dual citizenship ban passes, the law would:
- Require all current dual citizens to choose one nationality within one year of enactment.
- Treat failure to choose as a voluntary relinquishment of U.S. citizenship, meaning people would lose their American nationality by default.
- Automatically strip U.S. citizenship from anyone who acquires another nationality after the law’s effective date.
- Require federal agencies, such as the U.S. Department of State and the Department of Homeland Security (DHS), to build new databases and tracking systems to enforce the law.
The bill would go into effect 180 days after passage.
Constitutional and practical challenges
Legal experts warn the dual citizenship legislation may conflict with decades of constitutional precedent.
Under the Afroyim v. Rusk (1967) and Vance v. Terrazas (1980) decisions, the government cannot strip U.S. citizenship without a person’s voluntary, affirmative act.
The proposal’s mechanism, deeming citizenship lost through inaction, would likely collapse under court scrutiny.
Implementing the law presents massive logistical hurdles. The U.S. does not currently maintain a registry of dual citizens. Enforcing renunciation would rely heavily on self-reporting, passport-renewal checks, or voluntary disclosures. Critics say that could lead to errors, misidentifications, and unintended deprivation of citizenship.
The changes could also trigger severe tax consequences under U.S. expatriation laws for many affected individuals.
Who would be affected
If the ban passes, dual nationals, including naturalized citizens who kept their original nationality, children born in the U.S. to immigrant parents, and Americans who later acquire citizenship through marriage or descent, could all be forced to choose.
The bill could also impact high-profile dual citizens. Several media reports highlight that prominent figures, including foreign-born Americans, could face difficult choices.
Immigrant communities, especially those with large populations of dual-national individuals, have expressed concern.
The sudden requirement to renounce other citizenships or risk losing U.S. nationality would uproot many families’ sense of identity and ties abroad.
Why the senator is pushing it now
The move by Moreno comes amid a broader political climate of heightened concern over immigration, national security, and “American identity.” Supporters frame the legislation as aligning with efforts to protect U.S. sovereignty and ensure undivided loyalty from citizens.
Moreno says his own life story, immigrating from Colombia, renouncing his birth citizenship, and becoming American, embodies the kind of allegiance he believes all citizens should pledge.
Proponents also argue that dual citizenship complicates matters when citizens hold loyalties or legal obligations to foreign governments. They suggest ending dual nationality would prevent potential conflicts for public servants or individuals working in sensitive sectors.
Backlash and opposition concerns
Civil rights advocates warn the legislation threatens fundamental constitutional protections. They point out that automatic loss of citizenship without explicit consent violates the Fourteenth Amendment’s guarantee of citizenship and long-standing Supreme Court rulings.
Others say the law could disproportionately harm immigrant communities and families with strong cultural or familial ties abroad. The fear of losing U.S. citizenship unless they make an immediate, irrevocable choice has sparked anger and uncertainty.
Some commentators compare the bill to policies in authoritarian regimes that deny dual nationality, arguing that it undermines the pluralistic, global identity many Americans hold.
Practical enforcement also raises doubts: without a robust global tracking system and cooperation from foreign governments, many affected individuals might evade detection — leading to unequal enforcement.
What comes next
Moreno plans to formally introduce the bill in Congress soon. If the bill passes committee, it could trigger intense legal challenges, likely ending up before the Supreme Court.
Meanwhile, immigrant rights groups and legal experts are mobilizing to oppose the effort. They plan to highlight the constitutional conflicts and potential human rights implications.
The debate over dual citizenship has suddenly moved from academic and policy circles to a concrete legislative fight. For millions of Americans, and global families, the outcome could redefine what it means to be a U.S. citizen.
