This bill matters because it significantly changes who gets detained in the U.S. immigration system and gives states a new way to influence federal immigration policy. If passed, it means more non-citizens accused of certain crimes, even minor ones like shoplifting, would be automatically held in federal custody, potentially increasing detention costs and the number of people in federal holding facilities. This changes the discretion immigration officials currently have in some cases, pushing towards more mandatory detentions.

Furthermore, by allowing states to sue the federal government over immigration enforcement, it shifts power dynamics. States could more easily challenge decisions by federal agencies regarding who is detained, removed, or granted parole, especially if they claim even a small financial harm. This could lead to more legal battles between states and the federal government over immigration enforcement, potentially creating a less uniform national approach to immigration policy as states exert more influence through litigation.
