On December 1, 2025, Senator Bernie Moreno (R-OH) introduced the Exclusive Citizenship Act of 2025. The bill would prohibit any person from simultaneously holding U.S. citizenship and citizenship of another country. The major provisions include an effective date 180 days after enactment; the requirement that existing dual citizens would have one year to renounce all foreign citizenships or relinquish U.S. citizenship; the failure to renounce foreign citizenship within the one-year period would be treated as a voluntary relinquishment of U.S. citizenship under Section 349(a) of the Immigration and 26 Nationality Act (8 U.S.C. 1481(a); the voluntary acquisition of a foreign citizenship after enactment would trigger immediate loss of U.S. citizenship.
The legislation would require the Departments of State and Homeland Security to establish verification procedures and update federal records accordingly.
Senator Moreno’s office states that the bill is intended to ensure “sole and exclusive allegiance” to the United States. The senator, who was born in Colombia and renounced Colombian citizenship at age 18 upon naturalization, has described U.S. citizenship as “an honor and a privilege” that should not be shared with another nation.
