"The Fourteenth Amendment has always excluded from birthright citizenship persons who were born in the United States but not “subject to the jurisdiction thereof.” Consistent with this understanding, the Congress has further specified through legislation that “a person born in the United States, and subject to the jurisdiction thereof” is a national and citizen of the United States at birth, 8 U.S.C. 1401, generally mirroring the Fourteenth Amendment’s text. Among the categories of individuals born in the United States and not subject to the jurisdiction thereof, the privilege of United States citizenship does not automatically extend to persons born in the United States: (1) when that person’s mother was unlawfully present in the United States and the father was not a United States citizen or lawful permanent resident at the time of said person’s birth, or (2) when that person’s mother’s presence in the United States at the time of said person’s birth was lawful but temporary (such as, but not limited to, visiting the United States under the auspices of the Visa Waiver Program or visiting on a student, work, or tourist visa) and the father was not a United States citizen or lawful permanent resident at the time of said person’s birth."
