共和黨俄亥俄州參議員伯尼·莫雷諾（Bernie Moreno）近日提出一項具有爭議性的法案——《2025年專屬國籍法案》（Exclusive Citizenship Act of 2025），擬禁止美國公民擁有雙重國籍。該法案一旦通過，將要求美國公民對美國保持唯一效忠。如果同時持有其他國家國籍，必須在法案生效一年內放棄非美國國籍，否則將被視為自動放棄美國國籍。這項提案若付諸實施，不僅將改變現行允許雙重國籍的政策，還可能引發憲法層面的爭議，並對川普政府帶來政治壓力。根據現行法律，美國公民除非自願放棄國籍，否則無法被剝奪國籍，因此該法案的通過將對數百萬擁有雙重國籍的美國人帶來實際操作上的挑戰。

該法案的提出引起公眾對「第一家庭」可能受影響的關注。公開紀錄及其傳記顯示，美國第一夫人梅拉尼娅及她與前總統川普的小兒子巴倫（Barron Trump）均擁有美國與斯洛文尼亞雙重國籍。梅拉尼娅於2006年入籍美國，而保留斯洛文尼亞國籍則被認為為巴倫在歐洲工作提供便利，也為其未來生活和職業選擇帶來更多彈性。若法案最終通過，梅拉尼娅及巴倫將面臨在法定期限內選擇放棄非美國國籍的壓力，這不僅具有法律意涵，也可能引發社會和政治層面的關注與討論。

專家指出，該法案在法律和憲法層面存在諸多挑戰，尤其涉及公民權利與國籍自主權的基本問題。即便法案通過，其執行過程亦可能面臨法律訴訟與政策調整的阻力。此外，法案可能在政治層面造成分裂，因為雙重國籍在全球化背景下為個人提供更多靈活性與國際便利，而禁止雙重國籍則涉及國家安全、愛國義務與個人權利之間的敏感平衡。整體而言，這項法案不僅對特定家庭具有直接影響，也可能成為美國政治、法律與社會討論的新焦點。

Republican Senator Bernie Moreno of Ohio recently introduced a controversial bill, the Exclusive Citizenship Act of 2025, which seeks to prohibit U.S. citizens from holding dual nationality. If enacted, the law would require American citizens to maintain exclusive allegiance to the United States. Those who hold citizenship in another country would be required to renounce their non-U.S. nationality within one year of the law’s effective date, or they would be considered to have automatically forfeited their U.S. citizenship. If passed, this proposal would fundamentally change the current policy that allows dual citizenship and could provoke constitutional debates, while also placing political pressure on the Trump administration. Under current law, U.S. citizens cannot be stripped of their nationality unless they voluntarily renounce it, so the passage of this bill would present significant practical challenges for millions of Americans holding dual citizenship.

The bill has drawn public attention for its potential impact on the “First Family.” Public records and biographies indicate that First Lady Melania Trump and her son, Barron Trump, hold dual citizenship with both the United States and Slovenia. Melania became a U.S. citizen in 2006, and retaining Slovenian citizenship has reportedly provided Barron with flexibility for work opportunities in Europe and more options for his future. If the bill is ultimately enacted, both Melania and Barron could face the legal and personal pressure of deciding whether to renounce their non-U.S. nationality within the statutory timeframe, raising legal, social, and political implications.

Experts note that the bill raises significant legal and constitutional challenges, particularly regarding citizens’ rights and the autonomy of nationality. Even if the law is passed, its implementation could encounter legal disputes and require policy adjustments. Politically, the bill could be divisive, as dual citizenship provides individuals with increased flexibility and international opportunities in a globalized world. Banning dual nationality touches on sensitive issues involving national security, patriotic obligations, and individual rights. Overall, the bill not only directly affects specific members of the First Family but is also poised to become a focal point of broader political, legal, and social debates in the United States.
