On April 1, 2026, during oral arguments on Trump v. Barbara, the Supreme Court heard challenges to a Trump administration executive order that would deny birthright citizenship to children born to undocumented immigrants and most temporary visa holders. More justices appeared skeptical of the government’s position than of the challengers’ arguments.
What changed
The Trump administration resurrected a legal theory first defeated in the 1898 Wong Kim Ark case, arguing that “subject to the jurisdiction” means full political jurisdiction. Under this theory, babies of undocumented immigrants and lawfully present immigrants without green cards would not be entitled to birthright citizenship, because their parents’ presence is either temporary or banned.
During oral arguments, Solicitor General John Sauer argued that the 14th Amendment drafters sought only to offer birthright citizenship to children of formerly enslaved people, not all persons born in the United States.
Chief Justice Roberts suggested the Trump administration’s arguments were “quirky” and that the exceptions they proposed did not follow from the exceptions the Supreme Court acknowledged in Wong Kim Ark. When Sauer argued that modern policy reasons like “birth tourism” justified restricting birthright citizenship, Roberts responded: “It’s a new world, [but] it’s the same Constitution.”
Justice Gorsuch also questioned Sauer, noting it was “striking” how infrequently the concepts of allegiance and domicile — central to Sauer’s arguments — appeared in congressional debates around the 14th Amendment.
Why it matters
If the Supreme Court agrees with Trump’s theories, the ramifications would be severe. Hundreds of thousands of children are born each year to undocumented immigrants and people on nonimmigrant visas. These children would no longer be citizens, and some might even be rendered stateless depending on their parents’ status.
For immigration practitioners, the justices’ line of questioning at oral arguments signals skepticism toward the government’s position. Justice Kavanaugh noted that if the Court were to accept the traditional understanding of Wong Kim Ark and uphold precedent, “this is a short opinion.” This suggests a likely path to invalidating the executive order on precedential grounds rather than a broad constitutional rewrite.
The Court’s skepticism also matters to clients born to temporary visa holders or undocumented parents. A ruling upholding birthright citizenship could eliminate uncertainty about citizenship status at birth, while a narrow ruling confined to statutory or precedent grounds could affect future policy but may not reopen settled cases.
Way forward
-
Monitor the Supreme Court docket for the decision in Trump v. Barbara, expected by the end of June 2026. Subscribe to SCOTUS opinion alerts or check supremecourt.gov regularly.
-
Review current client files involving children born to undocumented or temporary visa-holding parents. Prepare to advise clients based on the Court’s final ruling, which may affirm decades of birthright citizenship practice or narrow its scope in unexpected ways.
-
Document the timing and circumstances of any child’s birth and parents’ immigration status. If the Court rules narrowly or remands certain questions, detailed records will support citizenship claims.
-
Consult the American Immigration Council’s blog and USCIS updates once a decision is released. Policy guidance from DHS may follow quickly, and practitioners should understand how the agency will implement whatever the Court decides.
