U.S. birthright citizenship and the Fourteenth Amendment

Legal analyses are examining the implications of the Fourteenth Amendment’s Citizenship Clause and the Supreme Court's decision in Trump v. Barbara. The decision holds that children born on U.S. soil to illegal aliens or unlawfully present foreigners are U.S. citizens.

Scholarly debate focuses on the distinction between birth on American soil and being ‘subject to the jurisdiction’ of the United States. While the majority opinion in Trump v. Barbara relies on the principle of jus soli (citizenship by place of birth), some legal perspectives suggest that birth in the U.S. creates a presumption of citizenship that could be overcome by evidence of a family's refusal of allegiance to the United States.

There is ongoing discussion regarding how this ruling affects the definition of a ‘natural born Citizen’ under the Presidential Eligibility Clause of the Constitution, noting that the Fourteenth Amendment citizenship definition and the originalist understanding of natural-born citizenship may involve different legal standards.
