Supreme Court Birthright Citizenship Case Threatens Newborns' Health Coverage

Last week, the Supreme Court heard arguments in Trump v. Barbara, a case challenging the constitutionally guaranteed birthright citizenship under the 14th Amendment. At stake is the fate of babies born in the United States to undocumented immigrants and those here legally but temporarily, such as visitors on student or work visas.

Currently, the 14th Amendment grants citizenship to anyone born on U.S. soil, and the Immigration and Nationality Act (INA) echoes this. This legal foundation ensures that newborns covered by Medicaid at birth are automatically enrolled for a full year without additional paperwork, guaranteeing critical health coverage during their most vulnerable stage of life. Medicaid currently covers 41 percent of U.S. births, making this an issue that affects millions.

If the Court sides with the Trump administration’s executive order, many children—including those born to parents lawfully present—could lose access to Medicaid. Even those who remain eligible will face bureaucratic hurdles proving their citizenship. States will lack clear proof of newborn citizenship, complicating automatic enrollment. Parents may struggle to provide immediate documentation, especially if they themselves lack U.S. passports or were born abroad. Complex questions about children’s immigration status will multiply, particularly when parents have mixed citizenship or residency statuses.

Justice Ketanji Brown Jackson highlighted these practical challenges during oral arguments, questioning how hospitals would determine citizenship at birth. Solicitor General Elizabeth Prelogar’s response—that birth certificates and Social Security numbers would be issued automatically and citizenship checks performed by computer—rings hollow to families who know the reality. The process to secure these documents is anything but immediate, yet newborns need medical care within days of birth. Automatic Medicaid enrollment is designed to bridge this gap, but without guaranteed birthright citizenship, that safety net could unravel.

This case is not just a legal abstraction. Without guaranteed health coverage, newborns risk missing vital well-baby visits and immunizations, exposing them to preventable health problems. Parents will face costly delays and confusing paperwork at a time when their focus should be on caring for their new child.

The Court’s decision, expected by the end of June, could reshape the very meaning of citizenship and access to healthcare for millions of infants. Stripping birthright citizenship is a direct attack on democratic principles and civil rights, with devastating consequences for the youngest and most vulnerable Americans. Every baby deserves to leave the hospital with both a car seat and health insurance—anything less is a betrayal of our nation’s promise.
