Story Highlights
- Republican lawmakers introduced the Citizenship Act of 2026 to restrict automatic citizenship for some children born in the United States.
- The proposal targets children whose parents entered the country illegally or travelled to the United States primarily to give birth.
- The legislation follows the Supreme Court’s rejection of President Donald Trump’s executive order limiting birthright citizenship.
- Supporters say Congress can create an exception for children of people participating in an unlawful “invasion,” while opponents argue the measure conflicts with the 14th Amendment.
What Happened
Republican lawmakers have opened a new legislative front in President Donald Trump’s effort to restrict birthright citizenship.
Sen. Jim Banks of Indiana introduced the Citizenship Act of 2026, legislation that would amend federal law to deny automatic citizenship to children born to certain immigrants who entered the United States illegally or travelled to the country through birth-tourism arrangements.
Texas Rep. Brandon Gill has backed a corresponding House effort built around the same legal theory.
- The legislation classifies mass illegal immigration as an ongoing invasion.
- It seeks to exclude children of illegal entrants from automatic citizenship.
- It also targets foreign visitors who come primarily to secure U.S. citizenship for a child.
- The proposal would amend federal immigration law rather than rely on a presidential order alone.
Banks introduced the measure after the Supreme Court rejected the president’s birthright-citizenship executive order in Trump v. Barbara.
That order sought to deny citizenship to children whose mothers were unlawfully or temporarily present in the United States when the fathers were neither citizens nor lawful permanent residents.
The Supreme Court upheld the longstanding rule that nearly everyone born on American soil is a citizen, subject to narrow historical exceptions.
Republicans now argue that Congress possesses independent authority to define those exceptions through its constitutional power over naturalisation.
Why It Matters
The legislation attempts to accomplish through Congress what the administration could not achieve through executive action.
Supporters argue that the Constitution’s citizenship clause applies only to people born in the United States who are fully subject to American jurisdiction.
They contend that parents who enter unlawfully, or who travel specifically to exploit birthright citizenship, should not automatically secure citizenship for their children.
- Republicans say citizenship should not reward illegal entry.
- The proposal seeks to discourage birth tourism and unlawful migration.
- It would reinforce the administration’s broader sovereignty and border-security agenda.
- It could force the courts to define how much authority Congress has over citizenship law.
Opponents argue that the 14th Amendment clearly grants citizenship to nearly all people born in the United States, regardless of their parents’ immigration status.
The Supreme Court’s 1898 decision in United States v. Wong Kim Ark established that children born in the country to foreign parents are generally citizens.
The recognised exceptions traditionally involve children of foreign diplomats, hostile occupying forces and certain members of sovereign Native American tribes under historical law.
The Citizenship Act attempts to expand the hostile-force exception by treating large-scale illegal immigration as an invasion.
Whether judges accept that theory would determine whether the legislation survives.
Political and Public Context
President Trump signed his birthright-citizenship order on his first day back in office in January 2025.
The policy became one of the most closely watched parts of the administration’s broader immigration crackdown.
Lower courts blocked the order before the Supreme Court ultimately ruled against it on the merits.
- The Court relied on the 14th Amendment and existing federal citizenship law.
- The ruling preserved citizenship for children born to undocumented and temporary immigrants.
- Republican lawmakers responded by calling for congressional action.
- Banks framed his bill as a direct answer to the Court’s decision.
Gill has separately investigated businesses accused of organising birth-tourism services.
His congressional task force has sought information from companies that allegedly market American maternity and immigration arrangements to foreign families.
Birth tourism is narrower than the broader question of children born to undocumented residents, but Republicans frequently connect the two issues as examples of citizenship rules being exploited.
The legislation also fits with the president’s wider midterm agenda, including tighter immigration enforcement, the SAVE America Act and stronger documentary citizenship requirements.
What Happens Next
The Citizenship Act faces substantial procedural and constitutional obstacles.
Republicans may be able to advance the measure in the House, but Senate passage would normally require 60 votes to overcome a Democratic filibuster.
The party does not currently appear to have enough support to reach that threshold.
- House committees may hold hearings on birth tourism and citizenship law.
- Republican leaders could bring the measure to a floor vote before the midterms.
- Senate Democrats are expected to block the legislation.
- Any enacted restriction would face an immediate constitutional challenge.
The legal question would be whether Congress can redefine who is “subject to the jurisdiction” of the United States through ordinary legislation.
Critics argue that a constitutional amendment would be required because Congress cannot override the 14th Amendment or the Supreme Court’s interpretation of it with a statute.
Supporters point to Justice Brett Kavanaugh’s separate reasoning in Trump v. Barbara, which indicated that existing federal law was an obstacle to the executive order and suggested Congress has an important role in defining citizenship rules.
Even if the bill stalls, it gives Republicans a prominent immigration issue for the 2026 campaign.
The proposal allows the party to argue that citizenship should reflect lawful membership in the national community rather than simply the location of a child’s birth.
Democrats will frame the effort as an unconstitutional attempt to weaken a post-Civil War guarantee.
The result is likely to be another major political and legal fight over who automatically becomes an American citizen and whether Congress has the power to narrow a right recognised for more than a century.
