A group of 24 Republican led states, including Indiana, filed an amicus brief with the U.S. Supreme Court on October 24, 2025, to support President Donald Trumps executive order challenging birthright citizenship. The move aims to reinterpret the 14th Amendment and deny automatic U.S. citizenship to children born in the country to undocumented immigrants or temporary visitors.

This development comes amid ongoing legal battles over Trumps January 2025 order, which lower courts have blocked nationwide. The states argue that the long standing interpretation of birthright citizenship is not settled law and needs Supreme Court review to address immigration concerns.

Understanding Birthright Citizenship Basics

Birthright citizenship stems from the 14th Amendment, ratified in 1868 after the Civil War. It states that all persons born or naturalized in the United States and subject to the jurisdiction thereof are citizens. For over 150 years, this clause has granted citizenship to nearly anyone born on U.S. soil, regardless of their parents status.

This principle, known as jus soli or right of soil, sets the U.S. apart from many nations that tie citizenship more to parental status or bloodline. Courts and scholars have debated the jurisdiction phrase, but rulings like the 1898 case United States v. Wong Kim Ark affirmed citizenship for children of legal immigrants. Critics of the broad view say it encourages illegal immigration by creating anchor babies, a term used in policy debates.

Supporters highlight its role in building a diverse nation. In recent years, with border crossings hitting record highs in 2024 and early 2025, the issue has gained urgency. Public opinion polls show divided views, with about 40 percent of Americans favoring changes to limit birthright citizenship, according to recent surveys.

Trumps Executive Order Details

President Trump signed Executive Order 14160 on January 20, 2025, his first day back in office after winning the 2024 election. Titled Protecting the Meaning and Value of American Citizenship, it directs federal agencies to deny citizenship documents to children born in the U.S. on or after February 19, 2025, if their parents are undocumented or hold temporary visas like tourists or students.

The order does not apply retroactively, so millions already born retain their status. It focuses on those not fully subject to U.S. jurisdiction, echoing arguments from Trumps first term. Implementation plans from U.S. Citizenship and Immigration Services outline stricter birth certificate reviews and potential denials for passports or Social Security numbers.

This builds on Trumps campaign promises for tough immigration reforms. In 2025 alone, the administration has deported over 1.2 million people, linking the citizenship policy to broader efforts like border wall expansions and military involvement in enforcement. Legal experts note the order tests executive power limits, similar to past attempts on DACA or travel bans.

The States Amicus Brief Explained

Led by Iowa Attorney General Brenna Bird and Tennessee Attorney General Jonathan Skrmetti, the 30 page brief urges the Supreme Court to take up the case and overturn lower court blocks. Indiana Attorney General Todd Rokita joined the coalition, emphasizing states rights in immigration matters. The document argues that courts have wrongly assumed birthright citizenship as foregone conclusion, ignoring historical intent to exclude children of aliens without allegiance to the U.S.

The states claim this reinterpretation would reduce incentives for illegal entry and ease strains on public services. They point to original framers debates, where senators like Edgar Cowan expressed concerns about foreign born children. The brief also criticizes nationwide injunctions by district judges, calling them overreach.

Here is a list of the 24 states involved:

• Iowa
• Tennessee
• Indiana
• Kentucky
• Utah
• Alabama
• Alaska
• Arkansas
• Florida
• Georgia
• Idaho
• Kansas
• Louisiana
• Mississippi
• Missouri
• Montana
• Nebraska
• North Dakota
• Ohio
• Oklahoma
• South Carolina
• South Dakota
• Texas
• West Virginia

This near unanimous Republican support underscores party unity on immigration, contrasting with Democratic led states that have filed opposing briefs.

Legal Challenges and Supreme Court Path

Lower courts have swiftly blocked the order. A Seattle federal judge issued a nationwide injunction days after the February 19 cutoff, followed by appeals courts in the Ninth and First Circuits upholding the blocks in rulings through October 2025. These decisions cite the orders conflict with settled precedent and constitutional text.

The Trump administration appealed to the Supreme Court in September 2025, asking for review in cases like CASA v. Trump. In June 2025, the Court limited the scope of nationwide injunctions but did not rule on the merits, allowing blocks only for specific plaintiffs. This procedural win has encouraged the push for full hearing.

Experts predict the conservative majority, with six justices appointed by Republican presidents, might take the case. A ruling could come by mid 2026, potentially reshaping citizenship laws. Critics warn of chaos, including family separations and lawsuits over existing citizens. Proponents see it as restoring constitutional balance.

Broader Implications for U.S. Immigration

If upheld, the order could affect hundreds of thousands annually, based on estimates from the Migration Policy Institute showing about 300,000 such births yearly before 2025 surges. It ties into Trumps mass deportation plans, which have already strained resources and sparked protests in cities like Los Angeles and New York.

Public reactions vary. On social media, supporters praise it as protecting American jobs and welfare, while opponents call it un American and a step toward authoritarianism. Recent events, like the August 2025 border crisis with over 250,000 encounters, fuel the debate. Economists argue immigrants contribute billions in taxes, but states like Indiana cite costs exceeding $1 billion yearly for services.

This policy echoes global trends, with countries like the UK tightening citizenship rules post Brexit. For families, it raises practical issues like access to education and healthcare. As the case advances, it could influence midterm elections and future reforms.
