On June 27th of this year, the U.S. Supreme Court decided the case, Trump v. CASA. The Court held that federal district courts lack the authority to issue nationwide injunctions. The Court, however, did not tackle the underlying issue that the nationwide injunction was issued to address President Trump’s executive order limiting birthright citizenship.
On December 5th, the Court agreed to take up the constitutional question of Trump’s executive order. The case will likely be argued in March or April of 2026 and will be decided in late June.
My prior piece on this topic addressed whether the text of the Fourteenth Amendment’s Citizenship Clause would grant U.S. citizenship to children born to illegal aliens. I would like to now focus on how the Citizenship Clause was interpreted closer to the time when it was adopted in 1868.
For reference, here are citizenship clauses of the Fourteenth Amendment and the Civil Rights Act of 1866. These came into being in the wake of the American Civil War.
The Citizenship Clause of the Fourteenth 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.
The Citizenship Clause of the Civil Rights Act of 1866:
That all persons born in the United States and not subject to any foreign power, excluding Indians not taxed, are hereby declared to be citizens of the United States…
The Fourteenth Amendment clause is based on the Civil Rights Act of 1866 clause and, though worded differently, have identical meanings.
At the time when the Fourteenth Amendment was ratified, the classes excluded from birthright citizenship were children born to: foreign ambassadors, enemy soldiers, all other foreign national with allegiance to another nation, and American Indians.
Let us now review three cases where America-born individuals had their U.S. citizenship called into question.
In 1898, the Supreme Court decided the case of United States v. Wong Kim Ark. Wong Kim Ark, the son of Chinese immigrants, was born and raised in San Francisco. In 1895, after a short trip to China, Wong returned to the U.S. and was detained by authorities and threatened with deportation. Wong sued, arguing that he was a citizen of the United States. The Supreme Court agreed with his claim. His parents were legal permanent residents; therefore, they no longer had political allegiance with China, a foreign power.
In 1890, according to the Heritage Foundation, Mary Devereaux, a pregnant Irish woman, was being held on a ship in New York Harbor awaiting immigration approval. Devereaux left the ship for medical treatment and then gave birth in a New York hospital. The Justice Department later denied her immigration application. Both Devereaux and her daughter were sent back to Ireland. Her daughter, though born in the United States, was not a citizen because her mother had no political allegiance to the United States and, therefore, was not born subject to its jurisdiction.
In 1885, also according to the Heritage, the State Department rejected Richard Greisser’s claim of U.S. citizenship. Greisser had been born in Ohio in 1867, 18 years earlier, but his German parents never intended to stay in the United States and returned to Germany shortly after his birth. Because Greisser’s parents owed no political allegiance to the United States, he was not born subject to its jurisdiction.
When the Supreme Court hears the case on Trump’s executive order, the justices need only answer one question: What would the Fourteenth Amendment’s meaning in 1868 say about granting American citizenship to children of illegal aliens at birth? Not only can the Court look at the text of the amendment, but it can also look to what the government understood the amendment – through its own actions — to mean during the decades after the amendment’s adoption.
The first case, the Supreme Court ruled that Wong Kim Ark had acquired citizenship at birth. The second and third cases, Mary Devereaux’s daughter and Richard Greisser, according to the U.S. government, did not acquire citizenship at birth. Though we did not see the same outcome in these cases, the approach to deciding these cases was the same: the political allegiance of the parent(s) was central to the analysis.
I expect this will be the approach that some of the Supreme Court justices will take when evaluating whether the American-born children of illegal aliens acquire citizenship at birth. From the precedent set back in the nineteenth century that the mere fact that a child born on U.S. soil does not automatically confer citizenship, I also expect that there will be a majority on the Court to uphold Trump’s executive order. This is what the Citizenship Clause of the Fourteenth Amendment would compel. A solid majority of the Court will conclude that the Citizenship Clause is more about who is not a citizen.
This, however, need not be the end of the story. The Court will only decide how the language of the Fourteenth Amendment would apply to the children born to illegal aliens. The American people could change the status of such children by having Congress act as it did a century ago when it passed the Indian Citizenship Act of 1924.
Whatever Congress chooses to do on this matter is clearly up to its members. The Supreme Court, however, has a duty to interpret the law correctly. This is especially true of the Fourteenth Amendment. The amendment was paid for with the blood of many Americans, North and South, black and white, Republican and Democrat. It was the price paid to extend citizenship to the nation’s 4.8 million black residents.
The Court should not agree with those challenging the constitutionality of Trump’s executive order. Placing its seal of approval on an erroneous interpretation of the Fourteenth Amendment’s Citizenship Clause would cheapen the value of American citizenship.
