The main purpose of the Exclusive Citizenship Act of 2025 is to establish that individuals who are citizens of the United States must have undivided loyalty to the country. The law aims to eliminate dual or multiple citizenship, asserting that U.S. citizenship should be exclusive and not shared with any foreign nationality. Key provisions of the Act include a clear prohibition on holding dual citizenship. If a U.S. citizen voluntarily acquires citizenship from another country after the law is enacted, they will automatically lose their U.S. citizenship.
