U.S. v. Wong Kim Ark, 169 U.S. 649 (1898) was a case involving an ethnically Chinese man born in San Francisco to non-citizen Chinese laborers who left the US to visit China on several occasions. Previously, Mr. Ark had been let in by saying he was a citizen but on one occasion, the customs official refused to accept this explanation and detained him.
To quote from the Court’s decision:
[QUOTE=The Supreme Court]
The foregoing considerations and authorities irresistibly lead us to these conclusions: The fourteenth amendment affirms the ancient and fundamental rule of citizenship by birth within the territory, in the allegiance and under the protection of the country, including all children here born of resident aliens, with the exceptions or qualifications (as old as the rule itself) of children of foreign sovereigns or their ministers, or born on foreign public ships, or of enemies within and during a hostile occupation of part of our territory, and with the single additional exception of children of members of the Indian tribes owing direct allegiance to their several tribes. The amendment, in clear words and in manifest intent, includes the children born within the territory of the United States of all other persons, of whatever race or color, domiciled within the United States. Every citizen or subject of another country, while domiciled here, is within the allegiance and the protection, and consequently subject to the jurisdiction, of the United States. 196 U.S. at 693.
To hold that the fourteenth amendment of the constitution excludes from citizenship the children born in the United States of citizens or subjects of other countries, would be to deny citizenship to thousands of persons of English, Scotch, Irish, German, or other European parentage, who have always been considered and treated as citizens of the United States. Id. at 694.
