Prohibit school staff from allowing federal immigration enforcement officers to access schools without a judicial warrant

Nebraska's LB 1034 prohibits school staff, contractors, and agents from allowing federal immigration enforcement officers access to school grounds or students for immigration enforcement purposes without a valid judicial warrant. The bill defines a "valid judicial warrant" as one issued by a judge or magistrate specifically authorizing the requested access, excluding immigration detainers or administrative documents. It explicitly allows schools to comply with valid judicial warrants, court orders, or respond to immediate threats to health or safety. This law directly affects all public K-12 schools in Nebraska and their employees by requiring federal immigration officers to obtain a court-issued warrant before entering school facilities for enforcement actions.
