Supreme Court Justice Amy Coney Barrett raised concerns about a potential shift in the understanding of U.S. citizenship, specifically regarding a proposal put forth during the Trump administration.

The Proposed Change to Birthright Citizenship

The proposal challenges the long-held interpretation of the 14th Amendment’s Citizenship Clause – “all persons born or naturalized in the United States, and subject to the jurisdiction thereof.” It aims to limit citizenship for babies born in the U.S. to undocumented immigrants and those on temporary visas.

Potential Impact and Concerns

Opponents estimate the policy could affect approximately 200,000 births annually and potentially leave some children stateless. Researchers and local officials have warned of increased burdens related to verifying parentage and immigration status at birth, as well as a potential growth in the undocumented population and mixed-status families.

Historical Context and Legal Challenges

The administration’s theory was met with resistance in lower courts, which uniformly blocked the order, citing its likely unconstitutionality and conflict with existing federal statute 8 U.S.C. § 1401. The 1898 Supreme Court case Wong Kim Ark affirmed the principle of jus soli – citizenship based on place of birth – with limited exceptions.

Justices' Questions During Oral Arguments

During oral arguments, Barrett questioned why a “new kind of citizenship” wasn’t debated during the 14th Amendment’s ratification. Chief Justice John Roberts challenged the government’s focus on modern concerns like birth tourism, stating, “It’s the same Constitution.” Justice Ketanji Brown Jackson inquired about the practicalities of verifying parentage, asking about potential depositions of mothers.

“If they were going to invent an entirely new kind of citizenship, like an American brand, why wouldn't we have seen more discussion of that,” Barrett stated, adding, “I think you have a number of hurdles to accomplish those two things.”

What Happens Next

The Supreme Court is expected to issue a decision by late June or early July. The court could rule on statutory grounds, avoiding a direct ruling on the 14th Amendment’s scope. Alternatively, it could address the constitutional question directly.

If the administration’s argument is rejected on statutory grounds, it could pursue legislation through Congress to modify birthright citizenship laws. Experts note that enforcing such limits would be complex and costly, potentially requiring a new federal verification system and risking errors that could lead to statelessness.
