Iowa has asked the U.S. Supreme Court to review a lower court ruling that blocked its state law targeting repeat illegal immigration offenders. The legislation, Senate File 2340, passed in April 2024, designates certain illegal immigration offenses as crimes under state law for individuals who have been previously deported or denied entry into the United States.
The law faced immediate legal challenges from pro-illegal immigrant advocacy groups. In October 2025, the Eighth Circuit Court of Appeals upheld a lower court injunction preventing enforcement. Iowa Attorney General Brenna Bird sought review by the full appeals court but that request was rejected, prompting the state to seek Supreme Court intervention.
Previously, the former Biden administration had sued to block the law, though the Justice Department withdrew its case after President Donald J. Trump assumed office. Iowa asserts the measure does not establish a separate immigration system but directly supports federal enforcement policies. The Federation for American Immigration Reform (FAIR) filed a brief supporting Iowa, arguing states may pass laws assisting federal immigration enforcement without conflict with federal authority.
Christopher J. Hajec, FAIR’s deputy general counsel, stated: “States have always had the right to defend themselves… by passing laws that assist the federal government in enforcing immigration laws.”
The case carries significant implications for state-level immigration enforcement. A Supreme Court ruling in Iowa’s favor would grant states broader authority to prosecute certain immigration violations, while a decision against Iowa could compel pro-border state governments to rely on Washington for responsible immigration policy—a situation absent under the Biden administration.
