Michigan — 287(g) Explosion and ICE Partnership Landscape 2025-2026

MI

Overview

Michigan went from zero 287(g) agreements to seven signed agencies in 2025, making it one of the fastest 287(g) expansions in the country. The state legislature is simultaneously pushing for more participation while a Democratic Senate tries to limit ICE enforcement powers.

287(g) Agreements by Model

Warrant Service Officer Model (jail-based)

Officers inside county jails can serve administrative immigration warrants and hold detainees for ICE pickup.

County/AgencySignedNotes
Jackson CountyMarch 2025First in Michigan. Sheriff Gary Schuette. Oldest active agreement.
Berrien County2025Followed Jackson model
Calhoun County2025Also has IGSA — dual agreement (detention + enforcement)

Task Force Model (field enforcement)

Officers can conduct limited immigration enforcement during routine police duties with ICE oversight. More aggressive model — requires more training but authorizes broader enforcement.

Legislative Pressure

Michigan House Resolution 128 (adopted): Encourages all county sheriffs and local law enforcement to enter 287(g) agreements with ICE.

Michigan Senate Bill 43 (introduced): Would require certain law enforcement agencies to perform immigration enforcement functions — going beyond voluntary 287(g).

Counter-legislation (Democrats):

  • SB 508: Reinstates sensitive locations policy (no ICE enforcement in schools, hospitals, churches without warrant)
  • SB 509: Prohibits sharing personal info with ICE without judicial warrant (did not advance to floor)
  • SB 510: Requires body cameras on immigration officers, limits mask-wearing
  • SB 508 and 510 passed committee March 25, 2026 along party lines. Face Republican opposition in House.

IGSA Network (Detention Agreements)

Four county jails hold ICE detainees under IGSAs:

  1. Calhoun County (Battle Creek) — 630 beds, also has 287(g)
  2. Chippewa County (Sault Ste. Marie) — 120 beds, Upper Peninsula
  3. Monroe County (Monroe) — near Ohio border
  4. St. Clair County (Port Huron) — Canadian border

Combined, these held 346 detainees in early June 2025.

Plus: 5. North Lake Processing Center (Baldwin, Lake County) — 1,800 beds, GEO Group private 6. Romulus warehouse (Wayne County) — 500 beds planned, paused under DHS review

Enforcement Numbers

  • 4,300+ ICE arrests in Michigan Jan 2025-Mar 2026
  • 1,075 arrests in 2025 alone (exceeding all of 2024)
  • Arrests of people without criminal convictions rose nearly ninefold comparing 6 months pre-inauguration to Jan 2026
  • 4,600+ people spent time in ICE custody in Michigan Jan-Oct 2025
