Republican Bernie Moreno of Ohio today unveiled the Exclusive Citizenship Act of 2025, a sweeping bill that would ban dual citizenship in the United States, forcing Americans who hold foreign nationality to pick a single allegiance or risk losing their U.S. citizenship.
Moreno, a naturalized American who renounced his Colombian citizenship decades ago, framed the bill as a matter of protecting national loyalty and preventing “divided loyalties” among citizens.
“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 told Fox News.
“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.”
According to the bill, existing law has allowed millions of Americans to hold multiple citizenships, something Moreno argues creates “conflicts of interest and divided loyalties.”
Under the proposed law:
• No American may simultaneously hold foreign citizenship.
• Anyone who obtains foreign citizenship after enactment automatically forfeits U.S. citizenship.
• Current dual citizens have one year to renounce their foreign citizenship — or they will be treated as having voluntarily relinquished their U.S. citizenship.
In its findings, Congress explicitly states:
“To preserve the integrity of national citizenship, allegiance to the United States must be undivided.”
Every U.S. citizen holding citizenship in another country would have one year after enactment to either formally renounce the foreign citizenship with the foreign government and notify the U.S. government, or voluntarily give up U.S. citizenship.
Failure to comply would result in automatic loss of U.S. nationality.
Noncompliance is treated the same as voluntarily abandoning U.S. nationality under immigration law.
It was an honor to pledge an Oath of Allegiance to the United States of America and ONLY to the United States of America.
