GOP Lawmakers Advance Legislation to Clarify Birthright Citizenship Limits

House Republicans are moving forward with legislation to restrict birthright citizenship for children of illegal immigrants, aiming to align federal policy more closely with the original understanding of the 14th Amendment following the Supreme Court's recent ruling. Rep. Glenn Grothman, R-Wis., chairman of a House subcommittee focused on immigration issues, is co-sponsoring the Birthright Citizenship Act as a key effort to address what he described as the ruling's significant national impact.

The bill would amend the Immigration and Nationality Act to limit automatic citizenship at birth to children born to parents who are U.S. citizens or nationals, lawful permanent residents residing in the United States, or non-U.S. nationals lawfully present and serving in the U.S. Armed Forces. Proponents argue this clarification would prevent the extension of citizenship to children of those in the country illegally or on temporary status, reducing incentives for birth tourism and chain migration.

Grothman stated he hopes Speaker Mike Johnson will schedule a House floor vote on the measure as early as this month. He expressed strong opposition to the Supreme Court's June 30 decision in Trump v. Barbara, which struck down President Trump's executive order seeking to end birthright citizenship for children of illegal immigrants or temporary visa holders. President Trump has indicated plans to seek a rehearing of that case. Grothman called the ruling the worst Supreme Court decision in his lifetime due to its effects on the country.

The legislation faces hurdles in the Senate, where the 60-vote cloture requirement could block passage without broader Republican majorities. Grothman noted disappointment if any Republicans opposed it and suggested that unified GOP control of Congress next year could advance the issue. He linked the push to concerns over large-scale illegal immigration, stating that the easiest way to alter America involves admitting people unfamiliar with its values and freedoms.

Data cited in discussions around the bill includes U.S. Citizenship and Immigration Services figures showing approximately 818,500 new citizens naturalized in 2024. Pew Research Center estimates indicate that in 2023, about 320,000 babies were born to mothers who were unauthorized immigrants or held temporary legal status, representing roughly 9 percent of total U.S. births. Grothman highlighted these trends as contributing to demographic and cultural shifts.

The representative also endorsed state-level actions to curb birth tourism and restrict benefits tied to citizenship status, noting such measures would be beneficial though dependent on supportive state leadership in places like Wisconsin. He emphasized that legal pathways to citizenship remain available, with hundreds of thousands successfully naturalized annually.

This congressional effort reflects ongoing Republican priorities to reinforce immigration enforcement and reinterpret citizenship rules in line with historical and constitutional intent. Supporters view the legislation as a necessary response to the Supreme Court's broad application of the 14th Amendment's Citizenship Clause, potentially setting the stage for further judicial review if enacted. The bill's advancement underscores tensions between executive, legislative, and judicial branches on one of the most consequential immigration-related policies.
