U.S. national

The United States nationality law is a uniform rule of naturalization of the United States set out in the Immigration and Nationality Act of 1952, enacted under the power of Article I, section 8, clause 4 of the United States Constitution (also referred to as the Nationality Clause), which reads: Congress shall power - "To establish a uniform Rule of Naturalization..." The 1952 Act sets forth the legal requirements for the acquisition of, and divestiture from, American nationality. The requirements have become more explicit since the ratification of the Fourteenth Amendment to the Constitution, with the most recent changes to the law having been made by Congress in 2001.

Adult citizens of the United States who are residents of one of the 50 states or the District of Columbia (Washington, D.C.) have the right to participate in the political system of the United States, as well as their state and local governments, (with most states having restrictions on voting by persons convicted of felonies, and a federal constitutional prohibition on naturalized persons running for President and Vice President of the United States), to be represented and protected abroad by the United States (through U.S. embassies and consulates), and to live in the United States and certain territories without any immigration requirements. Felons can vote in over 40 states, and in at least 2 while incarcerated. Felons can also serve jury duty if approved.
