Citizenship in the United States is a status that entails specific rights, duties and benefits. Citizenship is understood as a "right to have rights" since it serves as a foundation for a bundle of subsequent rights, such as the right to live and work in the United States and to receive federal assistance.
There are two primary sources of citizenship: (1) Birthright citizenship, in which a person is presumed to be a citizen provided that they are born within the territorial limits of the United States, or other circumstances existing at the time of their birth (for example, citizenship of a parent).(2) Naturalization, a process in which an immigrant applies for citizenship and is accepted.
These two pathways to citizenship are specified in the Citizenship Clause of the Constitution's 1868 Fourteenth Amendment which reads:All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.
