Tennessee – The Tennessee General Assembly has advanced legislation that strengthens cooperation between local law enforcement agencies and federal immigration authorities by requiring limited detention extensions for individuals subject to immigration detainers.

House Bill 2018 (HB 2018), sponsored by Rep. Mark Cochran (R–Englewood), requires certain Tennessee law enforcement agencies to hold individuals subject to federal Immigration and Customs Enforcement (ICE) detainers for up to 48 hours beyond their scheduled release time, allowing federal officials additional time to assume custody.

According to official bill text from the Tennessee General Assembly, HB 2018 requires participating law enforcement agencies—specifically those operating under federal 287(g) agreements—to “accept and honor” ICE detainers. This includes:

  • Holding an individual for up to 48 hours beyond their release time
  • Excluding weekends and holidays from the 48-hour calculation
  • Notifying federal immigration authorities before release
  • Allowing ICE time to take custody of the individual

The bill also ties enforcement to agencies that have formal agreements with federal immigration authorities under the 287(g) program, which allows local officers to assist in federal immigration enforcement.

Legislative timeline

HB 2018 moved quickly through the Tennessee legislature in 2026:

  • January 22, 2026 – Bill filed
  • March 25, 2026 – Advanced out of House committee
  • April 6, 2026 – Passed Tennessee House
  • April 14, 2026 – Passed Tennessee Senate (as amended)
  • Mid-April 2026 – Final legislative approval completed

The bill is scheduled to take effect on July 1, 2026, if signed into law.

Rep. Mark Cochran argued the bill strengthens law enforcement cooperation with federal agencies and ensures detainers are not ignored.

During committee discussion, Cochran stated the intent was to ensure Tennessee remains committed to enforcing immigration law through closer coordination with federal authorities.

During Senate consideration, the bill was amended to narrow its scope.

Originally, the legislation would have applied to all law enforcement agencies statewide. However, the final version limits the requirement to sheriff’s departments operating under federal 287(g) agreements.

Supporters said the change ensures the bill applies to agencies already formally cooperating with ICE, while critics raised concerns about costs and detention authority.

What this means

If enacted, the law would:

  • Extend local detention time for ICE pickup coordination
  • Strengthen formal cooperation between county sheriffs and federal immigration enforcement
  • Standardize compliance for agencies participating in 287(g) programs

Supporters describe it as a “public safety and enforcement coordination” measure, while opponents often argue similar policies can raise legal and civil rights concerns.
