In United States v. Wong Kim Ark, decided March 28, 1898, the Supreme Court ruled 6-2 that a person born on American soil to foreign-citizen parents is a citizen of the United States under the Fourteenth Amendment. The government could not bar Wong Kim Ark, born in San Francisco to Chinese parents, from reentering the country he had been born in. The decision remains the foundational precedent for birthright citizenship.
Who Wong Kim Ark Was
Wong Kim Ark was born in San Francisco in 1873. His parents were subjects of the Emperor of China who had made a permanent home in California and ran a business there. Neither held any diplomatic or official post.1Justia. United States v. Wong Kim Ark
He grew up in the city, lived there as an adult, and traveled to China for a temporary visit in 1890. When he returned aboard the steamship Gaelic that July, the collector of customs let him land “upon the sole ground that he was a native-born citizen of the United States.”2Supreme Court of the United States. United States v. Wong Kim Ark Federal officials, in other words, already recognized his citizenship.
Wong made another brief trip to China in 1894. When he returned aboard the Coptic in August 1895, the collector refused to let him land, on the sole ground that Wong “was not a citizen of the United States.”1Justia. United States v. Wong Kim Ark He was detained aboard the ship in San Francisco harbor and treated as an excludable alien under the Chinese Exclusion Act of 1882 and the tightening laws that followed it.3National Archives. Chinese Exclusion Act (1882)
On October 2, 1895, the U.S. District Court for the Northern District of California issued a writ of habeas corpus, forcing the government to justify his detention.1Justia. United States v. Wong Kim Ark Wong’s argument was simple: he was born in the United States, and the Fourteenth Amendment made him a citizen. The government answered that his parents were Chinese subjects who could never naturalize under existing law, so their son inherited a foreign allegiance and was not truly American. The case reached the Supreme Court, which decided it on March 28, 1898.
What the Court Held
Justice Horace Gray wrote for the majority. The holding was precise: a child born in the United States to parents of Chinese descent who were domiciled residents carrying on business, and who held no diplomatic or official role for a foreign government, “becomes at the time of his birth a citizen of the United States, by virtue of the first clause of the Fourteenth Amendment.”1Justia. United States v. Wong Kim Ark Wong Kim Ark was a citizen. The government had no authority to keep him out of his own country.
The Court grounded that answer in the text of the amendment: “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.”4Congress.gov. Amdt14.S1.1.2 Citizenship Clause Doctrine Justice Gray traced that language to English common law going back at least to Calvin’s Case in 1608, under which every child born within the sovereign’s territory was a natural-born subject regardless of the parents’ foreign status. The only recognized exceptions were children of foreign diplomats and children of enemy soldiers occupying territory by force.1Justia. United States v. Wong Kim Ark That rule, the Court concluded, carried into the American colonies, survived the Revolution, and was written into the Fourteenth Amendment. The amendment did not invent birthright citizenship. It constitutionalized a principle already centuries old.
The Court also settled the relationship between the Constitution and the exclusion laws. Congress had broad power to regulate immigration, but that power stopped at people who were already citizens by birth. No statute can override the Constitution, and since the Fourteenth Amendment defines citizenship, any law that tries to strip citizenship from someone born on American soil is invalid on its face.4Congress.gov. Amdt14.S1.1.2 Citizenship Clause Doctrine
What “Subject to the Jurisdiction” Means
The government’s best argument turned on five words: “subject to the jurisdiction thereof.” If that phrase demanded something more than physical presence within U.S. borders, then birth alone would not be enough. The government read it to require complete political allegiance. On that view, children born to foreign nationals inherited their parents’ loyalty and fell outside American jurisdiction.
The Court rejected that reading. “Subject to the jurisdiction” meant subject to the laws and authority of the United States, and that applied to virtually anyone physically present within the country. A resident alien who obeys American law, pays taxes, and can be prosecuted for crimes is under American jurisdiction. The phrase never required exclusive political loyalty.
The exceptions the Court recognized were narrow and closed. Children of foreign diplomats fall outside the Citizenship Clause because diplomats carry immunity from the host country’s laws. Children born to members of an enemy army occupying U.S. territory by force are excluded for the same reason: those individuals are not under American legal authority in any meaningful sense.1Justia. United States v. Wong Kim Ark Wong Kim Ark’s parents were private residents running a business, not diplomats or soldiers. Their son fell squarely within the clause.
One further boundary is worth noting because the Court addressed it in passing. In Elk v. Wilkins (1884), the Court had held that a Native American born as a member of a recognized tribe was not a citizen under the Fourteenth Amendment, on the theory that tribal members owed allegiance to their own nations. The Wong Kim Ark opinion narrowed that reasoning, saying Elk “had no tendency to deny citizenship to children born in the United States of foreign parents . . . not in the diplomatic service of a foreign country.” Congress later resolved the Native American question directly with the Indian Citizenship Act of 1924.5Justia. Elk v. Wilkins
The Dissent
Chief Justice Melville Fuller, joined by Justice John Marshall Harlan, dissented. Fuller argued that the Fourteenth Amendment was not meant to automatically confer citizenship on children whose parents were legally barred from ever becoming citizens themselves. An amendment written to protect formerly enslaved people, in his view, should not be read to strip the political branches of authority over the children of aliens the law deliberately excluded.
Fuller framed the issue as one of sovereignty. If the children of excludable aliens were automatically citizens, then Congress’s repeatedly upheld power to exclude classes of foreigners would be undermined, because an excluded group could simply have children on American soil who would be beyond the reach of exclusion laws. He also argued that treaties with China and existing naturalization laws should be read alongside the Fourteenth Amendment rather than overridden by it.1Justia. United States v. Wong Kim Ark
The majority rejected that reasoning, and no later Court has adopted it. The arguments themselves, however, have not disappeared.
Why the Case Still Matters
Congress codified the rule in 8 U.S.C. § 1401, which makes a person born in the United States and subject to its jurisdiction a citizen at birth.6Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth But the ruling itself remains the constitutional anchor, and the debate over its scope is live.
On January 20, 2025, the White House issued an executive order titled “Protecting the Meaning and Value of American Citizenship,” directing federal agencies to stop recognizing citizenship for children born in the United States in two categories: children whose mothers were unlawfully present and whose fathers were not citizens or lawful permanent residents, and children whose mothers were present on temporary visas with fathers who were not citizens or permanent residents.7The White House. Protecting The Meaning And Value Of American Citizenship
Federal judges quickly blocked the order, and the reasoning in those challenges traced back to Wong Kim Ark. The Citizenship Clause is a constitutional command, not a policy Congress or the President can override. The exceptions the 1898 Court recognized (children of diplomats and enemy occupiers) are closed. No statute, executive order, or treaty can add new categories of people born on American soil who are denied citizenship at birth.
The arguments against birthright citizenship today closely track Fuller’s dissent. Whether “subject to the jurisdiction” demands more than physical presence and obedience to American law has never left political discourse, even though the Supreme Court answered it more than a century ago. Anyone seeking to narrow birthright citizenship has to either distinguish Wong Kim Ark or ask the Court to overturn it.
