If someone is in the U.S. illegally and gets arrested, charged, or convicted for theft-related crimes like shoplifting or burglary, federal immigration authorities would be required to detain them rather than release them while their case proceeds. States would also gain new power to sue the federal government in court if they believe immigration officials made decisions—like releasing someone from custody or not enforcing removal orders—that caused the state or its residents harm, including harm as small as $100 in costs. In short, this tightens detention rules for immigrants accused of certain property crimes and gives state governments a legal tool to challenge federal immigration enforcement choices they disagree with.
