Tennessee lawmakers have signed off on a controversial measure that would force certain local law enforcement agencies to cooperate with federal immigration authorities and honor ICE detainers. The bill cleared the state Senate last Tuesday, the House signed on two days later, and the proposal is now headed to Gov. Bill Lee’s desk. If he approves it, the law kicks in July 1, 2026.
What the bill requires and what it could cost locally
House Bill 2018, the companion to SB 1486, targets law enforcement agencies that sign memoranda of agreement with federal officials. Those agencies would be required to “accept and honor” immigration detainers, a phrase the bill defines as holding a person in custody for up to 48 hours, not counting Saturdays, Sundays and holidays, and notifying federal immigration authorities before that person is released, according to the Tennessee General Assembly.
During the debate, senators adopted an amendment that narrows the mandate to sheriff’s departments that have signed a 287(g) memorandum of agreement with ICE. With that change in place, the Senate passed the bill on a 27-5 vote, and the House later concurred 76-18.
The state’s Fiscal Review Committee warns the measure may not be cheap. As of March 9, 2026, 67 law enforcement agencies in Tennessee have entered MOAs with ICE, and the committee projects that, under certain scenarios, local governments could see recurring cost increases of more than $5.39 million, according to the Fiscal Review Committee. That is not exactly pocket change for county budgets already juggling jail costs.
Pushback from advocates and lawmakers
Immigrant-rights advocates and some Democratic lawmakers are not buying the pitch that this will make communities safer. They argue the bill will damage already fragile relationships between immigrant residents and local police and could scare off victims and witnesses who might otherwise come forward to report crimes.
Lisa Sherman Luna, executive director of the Tennessee Immigrant and Refugee Rights Coalition, labeled the push “anti-immigrant” in a statement reported by the Nashville Scene. Rep. Larry Miller warned the package would “hurt Tennesseans,” a criticism that goes beyond immigrant communities and hints at broader public safety and financial concerns.
Local advocates have also raised alarms about potential civil liability if counties hold someone solely on an ICE detainer and a court later finds that detention unlawful, according to the same reporting. In other words, they fear counties could end up stuck with both the bill and the blame.
Where this fits nationally
The Tennessee bill lands in the middle of a broader national trend toward deeper collaboration between local police and ICE. An analysis by FWD.us points to a surge in 287(g) agreements and a substantial increase in federal incentives for local agencies that help enforce immigration law.
Federal regulations treat an ICE Form I-247 detainer as a request, not a judge’s order. That distinction in 8 C.F.R. §287.7 is one reason legal experts say holding someone solely on an administrative detainer raises constitutional and liability questions. Tennessee’s bill leans into that gray area by shifting more of the practical burden onto sheriffs who sign up for federal partnerships.
What happens next
The measure now sits on Gov. Bill Lee’s desk. He can sign it, veto it, or let it become law without his signature. If it does become law, the provisions take effect July 1, 2026.
Local officials still have one major lever. They can choose not to enter memoranda of agreement with ICE in the first place, which would keep their agencies outside the mandate. At the same time, political pressure and the lure of federal support could nudge more counties into these partnerships.
