The Supreme Court Is About to Rule on Birthright Citizenship—And Nobody Is Going to Like the Fallout

The Supreme Court is expected to issue its ruling in the birthright citizenship case as early as Thursday, June 18, according to reporting published by NPR and WTTW on June 15 and 16. The case challenges Executive Order 14160, which President Trump signed on January 20, 2025—his first day in office—restricting the automatic grant of U.S. citizenship to children born in the United States to parents who entered the country without authorization or are present on temporary visas. Every federal court that has reviewed the order has blocked it from taking effect, citing the 14th Amendment’s guarantee that all persons “born or naturalized in the United States and subject to the jurisdiction thereof” are citizens [1, 2].

The Justice Department has argued that the phrase “subject to the jurisdiction thereof” excludes children of unauthorized immigrants because their parents are not legally “domiciled” in the United States—a novel interpretation of a concept whose meaning varies significantly across different bodies of law. SCOTUSblog analysts noted the outcome may hinge precisely on the legal definition of “domicile,” and that multiple justices expressed pointed skepticism toward the administration’s position during April oral arguments. A ruling upholding the executive order would immediately affect thousands of newborns per year and trigger cascading questions about access to Medicaid, Social Security numbers, school enrollment, and U.S. passports for children born to foreign nationals [3, 4, 5].

Why It Sucks:

Immigration Restrictionists

• Every court has blocked the order, even before the Supreme Court weighs in. The executive order has faced a uniform wall of injunctions at every judicial level, meaning the administration’s position has not prevailed in a single courtroom; whatever the Supreme Court ultimately does, the legal path has been bruising and the outcome is uncertain in a court where several conservative justices appeared skeptical during oral arguments [1, 2].
• The “domicile” theory may not survive scrutiny from the right. SCOTUSblog’s analysis found that even on the conservative side, the novel legal argument advanced by the Justice Department rests on a contested reading of an 1868 constitutional clause that courts have consistently interpreted in favor of birthright citizenship for 150 years—a thin reed on which to hang the most significant citizenship change in American history [3].
• No legislation was passed to anchor the policy. An executive order is a far weaker instrument than a constitutional amendment or even legislation for a policy of this magnitude; even if the Court upholds the order, a future administration could repeal it on day one—meaning the policy is permanently unstable unless Congress acts [1, 4].

Immigration Advocates and Civil Liberties Groups

• A century and a half of constitutional precedent is genuinely at risk. The 14th Amendment has been understood to guarantee birthright citizenship since 1868; the administration’s argument would, if accepted, require reinterpreting the most foundational guarantee of American constitutional law through an executive order rather than the amendment process [1, 2].
• Upholding the order would create a permanent underclass of stateless children. Many children born in the U.S. to unauthorized parents would be citizens of neither the United States nor their parents’ country of origin under the laws of many nations; there is no clear legal pathway to any status for those children in the scenario where the order is upheld [1, 4].
• Even a victory at the Court doesn’t end the threat. If the justices strike down the executive order, the administration has signaled it will pursue statutory and potentially constitutional routes to the same goal; advocates are fighting a case whose outcome, whatever it is, does not resolve the underlying political campaign against the 14th Amendment’s citizenship guarantee [2, 4].

Healthcare Providers and State Officials

• There is no workable system for determining citizenship at the moment of birth. Hospitals are not equipped, staffed, or legally authorized to adjudicate immigration status in a maternity ward; a ruling upholding the order would create an immediate and unresolvable administrative crisis at the point of delivery for the nation’s roughly 3.6 million annual births [5].
• Thousands of newborns per year would immediately lose Medicaid and insurance eligibility. The Georgetown Center for Children and Families found the ruling could ripple through the healthcare system from the first moments of a child’s life, leaving maternity wards and pediatric units uncertain about coverage eligibility for newborns whose parents lack documentation—at exactly the moment when care cannot be withheld [5].
• States would face an unfunded implementation mandate with no clear mechanism. Birth certificates, school enrollment, public health programs, and state benefits all flow downstream from citizenship status at birth; forcing states and counties to make federal citizenship determinations on a per-birth basis—without guidance, infrastructure, or funding—is an administrative burden that no state health department or county clerk’s office is prepared to absorb [2, 4].
