President Donald Trump's effort to restrict birthright citizenship has evolved beyond the courtroom into a broader legislative campaign, with congressional Republicans advancing multiple bills designed to limit automatic U.S. citizenship for children born to certain noncitizens regardless of how the U.S. Supreme Court rules on the administration's executive order.
The legal battle centers on Trump's 2025 executive order, which seeks to reinterpret the Citizenship Clause of the 14th Amendment by denying automatic citizenship to children born in the United States whose parents are in the country illegally or temporarily on certain visas. The Supreme Court is expected to rule on the administration's challenge in Trump v. Barbara, but lawmakers aligned with the president have already introduced legislation that would pursue similar policy objectives through federal statute.
The parallel strategy reflects a broader Republican effort to reshape U.S. immigration policy on several fronts rather than relying solely on executive authority. While the executive order's constitutionality remains unresolved, members of Congress argue existing immigration laws should be amended to redefine who qualifies for citizenship at birth under federal law.
Leading that effort is the Birthright Citizenship Act, reintroduced by Rep. Brian Babin of Texas and Sen. Lindsey Graham of South Carolina shortly after Trump's second inauguration. The proposal would limit automatic citizenship to children born with at least one parent who is:
- A U.S. citizen;
- A U.S. national;
- A lawful permanent resident residing in the United States; or
- A lawful permanent resident serving in the U.S. military.
Supporters contend the legislation would reinforce what they view as the original meaning of the 14th Amendment while discouraging illegal immigration.
"American citizenship is a priceless privilege that must be protected, not exploited. We must restore integrity to our immigration system, uphold the rule of law, and protect the value of American citizenship for generations to come," Babin said when reintroducing the measure.
Opponents argue the proposal conflicts with more than a century of constitutional interpretation following the Supreme Court's 1898 decision in United States v. Wong Kim Ark, which broadly recognized birthright citizenship for nearly all children born on U.S. soil. Immigration advocates also warn the legislation could leave some children born in the United States without citizenship, potentially creating complex legal and humanitarian consequences.
The debate has increasingly centered on children born to undocumented immigrants, often described by critics of current law using the politically charged term "anchor babies." Republican lawmakers argue that automatic citizenship creates incentives for illegal immigration and eventually allows U.S.-born children to sponsor relatives through family-based immigration once they reach adulthood.
Supporters of the existing system note that U.S.-born citizens cannot petition for permanent legal status for their parents until age 21 under current immigration law, meaning citizenship does not provide immediate protection from deportation for undocumented parents.
The scale of the issue remains disputed.
The Center for Immigration Studies estimates that between 225,000 and 250,000 children were born to undocumented immigrants in 2023, representing roughly 7% of all U.S. births. While those estimates are frequently cited by immigration restriction advocates, other researchers have questioned both the methodology and broader policy conclusions.
The legislative push extends beyond birthright citizenship itself.
Republican lawmakers have also targeted what they describe as "birth tourism," in which foreign nationals allegedly travel to the United States on temporary visas to give birth so their children receive U.S. citizenship.
Sen. Marsha Blackburn's Ban Birth Tourism Act would make individuals who intend to give birth while visiting the United States ineligible for standard visitor visas. Separately, Sen. John Cornyn's BACK OFF Act would establish new criminal penalties for businesses that organize birth tourism services while creating a federal task force focused on enforcement.
Investigative journalist Peter Schweizer argued in his 2026 book The Invisible Coup: How American Elites and Foreign Powers Use Immigration as a Weapon that birth tourism has become a sophisticated international business, particularly in China. His reporting cites Chinese officials and private industry sources, although many of those figures have not been independently verified through official U.S. government data.
Available federal statistics remain limited because birth certificates generally do not record whether a pregnancy resulted from birth tourism. According to data cited from the Centers for Disease Control and Prevention, approximately 9,600 births in 2024 involved mothers who listed addresses outside the United States and its territories, though those figures do not establish intent to obtain citizenship.
