The bill mandates that each county sheriff in Wyoming must negotiate and enter into a written agreement with the United States attorney general for the enforcement of federal immigration and customs laws, as outlined in 8 U.S.C. 1357(g). This agreement must be made in consultation with the board of county commissioners and is required to cover aspects such as detentions, removals, and investigations related to immigration. Additionally, the bill establishes a reporting requirement where sheriffs must update the Wyoming attorney general on the status of these agreements by October 1 each year, including any reasons for declined agreements.

Furthermore, the bill stipulates penalties for counties that fail to comply with the agreement requirement. Specifically, counties that do not enter into or attempt to enter into the required agreement will be ineligible to receive state-administered federal funds related to law enforcement and training for each fiscal year of noncompliance. However, counties that report a decline from the United States attorney general will not face these penalties. The act is set to take effect immediately upon completion of the necessary legislative processes.
