Generally revise workers' compensation laws

This bill revises Montana's workers' compensation laws by clarifying who qualifies for coverage and establishing new eligibility rules. It explicitly includes lawfully employed aliens while prohibiting unlawfully employed aliens from receiving workers' compensation benefits. The legislation also requires insurers to close claims for individuals who leave the United States or certain U.S. territories while a claim is active. Additionally, the bill updates definitions to cover various groups such as vocational trainees, community service workers, and inmates in prison industries programs, while maintaining exclusions for volunteers and foster parents. These changes aim to streamline how workers' compensation claims are handled and define the scope of covered workers more precisely.
