Horace Gray, United States v. Wong Kim Ark…
“ The Fourteenth Amendment of the Constitution, in the declaration thatall 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. ”
