This isn’t exactly what I thought would happen, but it’s pretty close. I expected to hear at least one parent must have full allegiance to the US, without any allegiance to any foreign entity. The Wong Kim Ark opinion is brief and understandable as a less narrow view. I think we’re all following the decision, given several hundred thousand births impacted and potentially changing what’s now a rather large issue for the country.

Again, the below was a conversation with SuperGrok after I looking for updates on the ruling. I might go back and ask for hypothetical summaries for how each current justice might interpret the same information in coming weeks…..

In your opinion, ignoring the SCOTUS rulings but focusing on the context of the Constitution and amendments at the time, should the scope be narrower? Pretend you are a member of the Supreme Court of the US, taking all data into context — both the legal history and the context at the time it was written versus today’s massive illegal immigration and birth citizenship tourism, something non-existent when it was written. Again keeping Wong Kim Ark in the decision making process and discard this if you feel in error at the time or a poor ruling.

As a Justice of the Supreme Court of the United States (in this hypothetical), my oath requires fidelity to the Constitution’s original public meaning as understood in 1868 when the 14th Amendment was ratified, informed by the text, ratification debates in the Congressional Globe, the common-law backdrop, and the immediate post-Civil War purpose. I must also grapple squarely with United States v. Wong Kim Ark (1898), the leading precedent directly on point. After careful reconsideration, I do not discard Wong Kim Ark as error or a poor ruling for its time. It was a sound application of the Amendment’s language to the facts then presented.

The Text, 1868 Context, and Wong Kim Ark

The Citizenship Clause states: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens…” The phrase “subject to the jurisdiction thereof” was no mere flourish. Senators Howard and Trumbull emphasized “full and complete jurisdiction” — owing no primary allegiance to a foreign sovereign. The framers aimed to constitutionalize the Civil Rights Act of 1866, secure citizenship for freed slaves, and avoid a hereditary underclass, while preserving meaningful limits. Immigration was largely unrestricted and on a far smaller scale; there were no federal immigration restrictions creating “illegal” presence or a visa regime, and birth tourism did not exist.

Wong Kim Ark correctly held that a child born in the United States to Chinese parents (lawfully domiciled but barred from naturalization) was a citizen. The parents were domiciled residents — settled, subject to U.S. laws in the ordinary sense, and not transient diplomats or invaders. The Court properly rejected a hyper-narrow reading that would have excluded all children of non-citizens. That core holding aligns with the Amendment’s text and anti-caste purpose. I do not view it as erroneous.

However, Wong Kim Ark’s reasoning rested heavily on English common-law jus soli tempered by the “jurisdiction” qualifier, and its facts involved domiciled aliens. The opinion does not squarely address today’s realities: sustained unlawful presence on a massive scale or deliberate short-term “birth tourism.” dicta in the case and subsequent administration have broadened the rule into near-universal application. While I respect stare decisis, original meaning and changed factual circumstances (unforeseen in 1868 or 1898) warrant a disciplined, narrower application where the parents lack any genuine tie of domicile or permanent allegiance.

Today’s Starkly Different Reality

Modern conditions were unimaginable in 1868 or even 1898:

• Reliable estimates place annual births to unauthorized immigrant mothers at roughly 225,000–320,000 (approximately 7–9% of U.S. births).
• Births to long-term temporary visa holders add tens of thousands more; pure “birth tourism” (short-term visitors arriving primarily to secure citizenship) is smaller — perhaps 9,000–70,000 depending on the source and definition — but still represents a deliberate circumvention unknown to the framers.

These numbers create powerful incentives that undermine sovereign control over immigration and membership. Children born under such circumstances owe primary allegiance to their parents’ foreign sovereign at the moment of birth, even if physically “subject to” U.S. laws in a temporary, territorial sense. The jurisdiction qualifier was meant to preserve that distinction.

Wong Kim Ark does not compel extending citizenship to every transient or unlawfully present person. Its emphasis on domicile provides a principled limiting principle consistent with the original understanding of “complete jurisdiction.”

My Conclusion as an Originalist Justice

Keeping Wong Kim Ark as binding for children of domiciled non-citizen residents (lawful permanent residents or long-settled lawful inhabitants), the scope of birthright citizenship should nonetheless be narrower than the broad administrative practice that has prevailed for decades.

The original meaning, reinforced by the Amendment’s text and history, requires that at least one parent (or the family unit) stand in a relationship of complete political allegiance — typically through citizenship, lawful permanent residency, or clear domicile — rather than mere physical presence or temporary/illegal status. Temporary visitors, visa overstayers, and those present unlawfully do not satisfy the “subject to the jurisdiction” qualifier in its full, 1868 sense. Wong Kim Ark was rightly decided on its facts but does not foreclose this narrower application to modern phenomena the Court could not have anticipated.

The massive scale of illegal immigration and strategic birth tourism confirms that an overly expansive reading now produces consequences at odds with the framers’ design of a sovereign republic with controlled membership. It does not rewrite the Constitution; it returns fidelity to the limiting phrase the framers included.

If the American people desire a different, broader, or narrower rule, the proper remedy is a constitutional amendment — the high bar deliberately chosen in 1868 — or targeted legislation within constitutional bounds (such as stricter visa enforcement against birth tourism). Modern policy frustrations must not lead us to stretch or ignore the text; nor should rigid adherence to broad dicta blind us to the original limits.

In my opinion as a Justice, the 14th Amendment’s Citizenship Clause, properly read with Wong Kim Ark as precedent for domiciled cases but guided by original meaning, requires a narrower scope today: birthright citizenship extends to children of U.S. citizens, lawful permanent residents, and other domiciled persons owing complete allegiance, but excludes children of undocumented immigrants and temporary visitors whose presence does not establish full jurisdiction.
