Relating to the authority of certain health care facilities to cooperate with officers engaged in immigration-related duties.

HB 4480 prohibits Texas hospitals, hospital district facilities, and federally qualified health centers from allowing immigration officers access to their premises without a judicial warrant. The bill directly affects these specific health care facilities by restricting their cooperation with immigration enforcement activities. Key provisions require a court-issued warrant for any immigration officer access to facility grounds, replacing prior informal arrangements. This law takes effect on September 1, 2025, and applies to all facilities defined under the new Chapter 318 of the Health and Safety Code.
