Wyoming — Highway Patrol 287(g) creates statewide immigration enforcement, first state police force deputized in Mountain West

WY

Overview

On July 28, 2025, Governor Mark Gordon formalized a 287(g) Task Force Model agreement between the Wyoming Highway Patrol (WHP) and ICE. This made Wyoming one of the first states to deputize its state highway patrol for immigration enforcement, creating a statewide enforcement net that extends well beyond the five counties with individual sheriff 287(g) agreements.

Key Details

  • Agreement signed: July 28, 2025
  • Model: Task Force Model (broader authority than Warrant Service Officer model)
  • Authority: WHP officers can access ICE databases, determine immigration status, take enforcement action, and develop evidence against individuals violating immigration law
  • Cost: No additional cost to the state; free training from ICE
  • Scope: Statewide — WHP operates on all Wyoming highways
  • Rollout: Phased implementation

Why This Matters

The WHP 287(g) is a force multiplier for a state with vast geography and limited ICE presence (one ERO office in Casper). Any WHP traffic stop anywhere in Wyoming can now become an immigration enforcement encounter. Combined with the five county sheriff 287(g) agreements (Campbell, Carbon, Laramie, Natrona, Sweetwater), this creates near-total coverage of Wyoming’s population centers and major highways.

The November 2025 trucker operation demonstrated how this works in practice: WHP, Laramie County Sheriff, and ICE collaborated on a 3-day operation that produced 40 deportations from commercial vehicle stops near the Colorado border.

Note: Carbon County’s 287(g) was still under review by the County Attorney’s Office as of August 2025. Sheriff Alex Bakken estimated finalization in “at least another month.”

ACLU Critique

ACLU of Wyoming Director Antonio Serrano criticized the agreements as being signed without offering the public a chance to comment, and specifically raised concerns about the WHP’s authority to arrest undocumented immigrants across the five 287(g) counties plus anywhere along Wyoming’s highway system.
