text: Individuals born in any of the 50 U.S. states, the District of Columbia or almost any inhabited territory are United States citizens (and nationals) by birthright. The sole exception is American Samoa, where individuals are typically non-citizen U.S. nationals at birth. Foreign nationals living in any state or qualified territory may naturalize after going through the legal process of qualifying as permanent residents and meeting a residence requirement (normally five years).
  History
  Constitutional foundation
  Nationality defines the legal relationship between a person and a state or nation, specifying who is a member or subject of a particular nation. The rights and obligations of citizenship are defined by this relationship, as well as the protections to which nationals are entitled. Though nationality and citizenship are distinct and the United States recognizes the distinction between those who are entitled or not entitled to rights, its statutes typically use the words "citizen" and "citizenship" instead of "national" and "nationality". The Constitution of the United States did not define either nationality or citizenship, but in Article 1, section 8, clause 4 gave Congress the authority to establish a naturalization law. Before the American Civil War and adoption of the Fourteenth Amendment, there was no other language in the Constitution dealing with nationality.
