A new proposal introduced in the Senate has alarmed millions of people with dual citizenship. The text, still in its initial stages, is already generating concern.cupaction in immigrant communities.
The initiative comes from a legislator who arrived in the United States as a child and who, decades later, defends a model of citizenship without shared spaces. His proposal seeks to transform a principle accepted for generations.
A project that seeks to limit dual nationality.
Republican Senator Bernie Moreno of Ohio introduced the Exclusive Citizenship Law of 2025A proposal that would eliminate dual citizenship for all U.S. citizens. Moreno, born in Bogotá and naturalized at 18, maintains that loyalty to the country should not be divided.
“Being a U.S. citizen is an honor and a privilege, and if you want to be American, it’s all or nothing. It’s time to end dual citizenship for good.”, said on its website when announcing the project. It also stressed that taking the oath of allegiance to the United States should be a “unique and exclusive” act.
Moreno argues that current regulations allow situations that could generate conflicts of interest, since some Americans hold a second nationality without legal restrictions.
It was an honor to pledge an Oath of Allegiance to the United States of America and ONLY to the United States of America.

What would change in the law if it were to be passed?
El project It establishes that no person could be a citizen of the United States and, at the same time, retain another foreign citizenship. Those who already possess dual citizenship would have a maximum period of one year after the enactment of the law to decide which one to keep.
The proposal requires a formal resignation:
- To foreign citizensbefore the Secretary of State.
- Or to US citizenshipbefore the Secretary of Homeland Security.
Anyone who does not complete that process within the time limit would be considered as someone who voluntarily renounced their U.S. citizenship, following the provisions of section 349(a) of the Immigration and Nationality Act.
The State Department would have to issue regulations to verify these renunciations and update federal records. Furthermore, the initiative mandates coordination with the Department of Homeland Security and the Attorney General to properly identify those who lose their citizenship and treat them as foreign nationals for immigration purposes.
Dual citizenship in the United States today
U.S. law does not prohibit a naturalized or U.S.-born person from acquiring another citizenship through birth, descent, or residence abroad. Nor does it require prior authorization from courts or government agencies, according to the State Department.
This flexibility has been part of the country's migratory dynamics, which includes millions of citizens with ties to two territories.
USCIS reminds the public that the country continues to welcome new citizens.
The U.S. Citizenship and Immigration Services points out that the United States has a long tradition of welcoming immigrants. Over the past decade, more than 7.9 million people They obtained citizenship through naturalization.
In fiscal year 2024 alone, 818 thousand Immigrants managed to become citizens. Although the figure was lower than the previous year, the total for the last three years exceeds 2.6 million of new Americans.
Moreno's proposal opens a national debate on the current limits of dual citizenship and the impact of forcing millions of residents to choose between two identities. For now, the bill is beginning its legislative process, but it is already sparking a heated public discussion about belonging, loyalty, and the future of immigration.
