TX HB2257

Requires all Texas county sheriffs to apply for and maintain participation in the federal 287(g) immigration enforcement program, which delegates certain federal immigration enforcement powers to local law enforcement

Establishes tiered deadlines for participation based on county population: counties with 250,000+ residents must apply by July 1, 2026; counties with 75,000-250,000 by July 1, 2027; and counties with 75,000 or fewer by July 1, 2028

Mandates that sheriffs in larger counties (over 75,000 population) seek the "jail enforcement model" for processing removable noncitizens, while smaller counties may choose between the jail model or "warrant service officer model"

Authorizes the Attorney General to sue non-compliant sheriffs in Travis County district court and recover costs including attorney's fees; successor sheriffs are prohibited from ending agreements signed by predecessors

Creates a comptroller-administered financial assistance program to help sheriffs cover costs of participation, including officer salary offsets during federally-required training (capped at 25 officers per year) and reimbursement for required equipment
