Senator Bernie Moreno (R-OH) introduced a bill banning dual citizenship, ensuring that citizens pledge their sole allegiance to the United States.
“One of the greatest honors of my life was when I became an American citizen at 18, the first opportunity I could do so,” Moreno said in a statement. “It was an honor to pledge an Oath of Allegiance to the United States of America and ONLY to the United States of America! Being an American citizen is an honor and a privilege—and if you want to be an American, it’s all or nothing. It’s time to end dual citizenship for good.”
Moreno was born in Colombia.
The bill, called the “Exclusive Citizenship Act of 2025,” states that “an individual may not be a citizen or national of the United States while simultaneously possessing any foreign citizenship.” A citizen of the United States who acquires foreign citizenship after the legislation’s enactment “shall be deemed to have relinquished United States citizenship.”
Should U.S. citizenship be relinquished, the individual will be “appropriately recorded in Federal systems and treated as an alien for purposes of the immigration laws.”
Those with dual citizenship are given one year to comply with the legislation or lose their United States citizenship. Current law allows U.S. citizens to maintain foreign citizenship, a policy that may create conflicts of interest.
The legislation is intended to “preserve the integrity of national citizenship” and enforces “undivided” allegiance to the United States.” It adds, “It is in the national interest of the United States to ensure that United States citizenship is held exclusively.”
