Bernie Moreno proposes dual citizenship ban

United States Senator Bernie Moreno has introduced the Exclusive Citizenship Act of 2025, a bill aimed at prohibiting US nationals from holding dual citizenship. Moreno, who previously renounced his Colombian citizenship, argues that dual nationality creates 'conflicts of interest and divided loyalties.' If passed, the legislation would significantly impact thousands of dual nationals, including prominent figures like Melania Trump (who holds United States and Slovenia citizenship) and a substantial number of Nigerians who have naturalized in the United States. Data from the United States — United States Department of Homeland Security indicates that 38,890 Nigerians became naturalized US citizens between 2021 and 2023. This proposal comes amidst ongoing debates on immigration and citizenship in the United States, following a previous executive order by Donald Trump to restrict automatic citizenship for children of undocumented immigrants, which is currently stalled by legal challenges.
