169 U.S. 649 (1898)
The case of United States v. Wong Kim Ark is a pivotal Supreme Court decision that resolved ambiguities surrounding the interpretation of the citizenship clause of the Fourteenth Amendment.
Does the Fourteenth Amendment grant citizenship to children of foreign nationals born on U.S. soil, specifically to a child born to Chinese parents who are subjects of a foreign power?
The Fourteenth Amendment confers citizenship to all persons born or naturalized in the United States and subject to the jurisdiction thereof, affirming the doctrine of jus soli.
The Supreme Court held, in a 6-2 decision, that Wong Kim Ark, having been born in the United States, was a U.S. citizen by virtue of the Fourteenth Amendment.
The decision in United States v. Wong Kim Ark is significant for clarifying and cementing the concept of birthright citizenship under U.S. constitutional law. The case affirms the principle that citizenship by birthright is constitutionally protected, offering clarity and protection for children of immigrants born in the U.S., which is particularly pertinent in debates over immigration and citizenship rights.
