Republican Senator Bernie Moreno (Ohio) has announced his intention to introduce the Exclusive Citizenship Act of 2025 to Congress, which effectively abolishes dual citizenship for US citizens. The bill stipulates that Americans will not be able to hold US citizenship and the citizenship of any other country at the same time.
According to specialized media reports, the bill contains two key provisions. First, any person who applies for foreign citizenship after the law comes into force will automatically be considered to have renounced their US citizenship. Second, current dual citizens will be given a one-year transition period during which they must either renounce their foreign passport or notify the authorities in writing of their renunciation of US citizenship. Failure to do so will result in the loss of US citizenship.
Enforcement of the law will be entrusted to the State Department and the Department of Homeland Security, which will be required to create systems for registering individuals who have lost their citizenship and mechanisms for monitoring compliance with the new rules. The initiative has already sparked debate in the media, particularly because it could affect well-known public figures who hold dual citizenship.
Experts note that the bill will face challenges from both a political and legal standpoint. The US Supreme Court, in a series of decisions, including Afroyim v. Rusk (1967) and Vance v. Terrazas (1980), has clearly established that a citizen cannot be deprived of citizenship without voluntarily renouncing it, and that the mere existence of dual citizenship cannot automatically be interpreted as grounds for its loss.
Given these precedents, as well as the political situation in Congress (resistance from Democrats and likely reservations from some Republicans), the chances of the bill being passed in its current form appear slim. Most likely, the initiative will become part of the domestic political debate on immigration and citizen loyalty.
