United States v. Wong Kim Ark
The Fourteenth Amendment of the Constitution, in the declaration that
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,
contemplates two sources of citizenship, and two only: birth and naturalization. Citizenship by naturalization can only be acquired by naturalization under the authority and in the forms of law. But citizenship by birth is established by the mere fact of birth under the circumstances defined in the Constitution. Every person born in the United States, and subject to the jurisdiction thereof, becomes at once a citizen of the United States, and needs no naturalization. A person born out of the jurisdiction of the United States can only become a citizen by being naturalized, either by treaty, as in the case [p703] of the annexation of foreign territory, or by authority of Congress, exercised either by declaring certain classes of persons to be citizens, as in the enactments conferring citizenship upon foreign-born children of citizens, or by enabling foreigners individually to become citizens by proceedings in the judicial tribunals, as in the ordinary provisions of the naturalization acts.
The power of naturalization, vested in Congress by the Constitution, is a power to confer citizenship, not a power to take it away. "A naturalized citizen," said Chief Justice Marshall,
becomes a member of the society, possessing all the rights of a native citizen, and standing, in the view of the Constitution, on the footing of a native. The Constitution does not authorize Congress to enlarge or abridge those rights. The simple power of the National Legislature is to prescribe a uniform rule of naturalization, and the exercise of this power exhausts it so far as respects the individual. The Constitution then takes him up, and, among other rights, extends to him the capacity of suing in the courts of the United States, precisely under the same circumstances under which a native might sue.
