This page is information, not legal advice. Iowa requires full cooperation with federal immigration authorities under Iowa Code Chapter 27A - there are no sanctuary policies permitted at any level of local government. Iowa Senate File 2340 (SF 2340), signed April 10, 2024, would have made it a state crime to be in Iowa after deportation, denial, or removal - but the law was blocked by a federal district court in June 2024 and that block was upheld by the U.S. Court of Appeals for the Eighth Circuit in January 2025 AND October 2025. As of mid-2026, SF 2340 remains blocked; litigation continues. The Iowa State Patrol has a 287(g) agreement with ICE. Iowa's agriculture, meatpacking, and healthcare industries are heavily dependent on immigrant labor - more than half of Iowa's meat processors are immigrants.

Iowa sits in an instructive position in this series: a state whose political leadership has pushed for the most aggressive state immigration enforcement laws in its region, but whose most ambitious law - SF 2340 - has now been blocked twice by the federal appellate court. What remains in operation is the foundational cooperation framework in Iowa Code Chapter 27A, the Iowa State Patrol's 287(g) agreement, and growing county-level cooperation in some areas. What Iowa lacks, unlike Florida or Indiana, is a completed mandatory detention law - SF 2340 never took effect. The enforcement reality in Iowa reflects aggressive federal posture operating through existing channels, without the additional state criminal enforcement layer that SF 2340 would have added.
Part 1: What federal immigration law actually says
Federal authority and the preemption cases
Immigration enforcement is federal. The INA governs all removability and status determinations. The Tenth Amendment's anti-commandeering doctrine (Printz v. United States, 1997) means the federal government cannot compel states to enforce immigration law - states must voluntarily cooperate. Iowa has chosen broad voluntary cooperation under Chapter 27A. SF 2340 went further - attempting to create state crimes for immigration status - and was blocked on preemption grounds because Congress has comprehensively occupied the field of immigration law, and states cannot create parallel criminal enforcement systems in that space.
What SF 2340 attempted and why courts blocked it
SF 2340 was modeled after the Texas SB 4 statute - a pattern now seen in Idaho (HB 83), Florida (SB 4-C), and Iowa. All three have been blocked on preemption grounds. The Eighth Circuit's analysis in Iowa mirrors that of courts in other circuits: states cannot make it a state crime to be present in violation of federal immigration law, cannot empower state judges to order deportation, and cannot create arrest powers over federal immigration violations when Congress has reserved those functions to federal authorities.
Part 2: Iowa's immigration enforcement framework
Iowa Code Chapter 27A - mandatory cooperation
Iowa Code Chapter 27A is the existing state law requiring full cooperation between all Iowa law enforcement agencies and federal immigration authorities. This law: prohibits sanctuary policies at any level of local government; requires law enforcement to cooperate with ICE detainer requests; requires sharing of immigration status information with federal immigration authorities; and bars any local ordinance, resolution, or policy that would limit cooperation with ICE. There are no sanctuary cities in Iowa. Governor Kim Reynolds has actively enforced this requirement - in February 2025, she publicly posted a letter about the Winneshiek County Sheriff's Office, applying pressure on a sheriff who appeared to be limiting ICE cooperation.
SF 2340 (Senate File 2340) - passed but BLOCKED
SF 2340 was signed by Gov. Reynolds on April 10, 2024. The law would have: made it an aggravated misdemeanor state crime for anyone who had ever been deported, removed, or denied admission to the U.S. to be present in Iowa - even if they had subsequently received lawful status or permission to return; empowered state and local law enforcement to arrest people for this state crime; and required state judges to order deportation as part of sentencing.
The law was blocked by U.S. District Judge Stephen Locher (Southern District of Iowa) on June 17, 2024 - before it could take effect on July 1, 2024. Iowa AG Brenna Bird appealed. The U.S. Court of Appeals for the Eighth Circuit upheld the injunction in January 2025 and again in October 2025. The case is Iowa Migrant Movement for Justice v. Bird. The Trump administration's DOJ also filed its own separate lawsuit seeking to block SF 2340 (on the federal preemption theory that states cannot create their own immigration enforcement scheme), a notable alignment of the Trump administration with the injunction on legal grounds.
As of mid-2026, SF 2340 remains blocked. Verify current status at aclu-ia.org. The litigation is ongoing and could continue to the U.S. Supreme Court. Until a final resolution, SF 2340's criminal provisions cannot be enforced.
What SF 2340's block means - and does not mean
The injunction blocking SF 2340 means that Iowa cannot prosecute anyone under its state immigration crime provisions. It does not mean that federal immigration enforcement in Iowa has stopped or slowed. ICE operates independently of SF 2340. ICE arrests in Iowa occur under federal authority through the Iowa State Patrol's 287(g) agreement, informal cooperation between county agencies and ICE, and independent federal enforcement. The block on SF 2340 protects people from state prosecution - not from federal immigration enforcement.
The notable overreach of SF 2340 - children and lawfully present people
The ACLU of Iowa specifically highlighted that SF 2340, as written, would have created criminal liability for a child who returned to Iowa after deportation - even if that child now had lawful immigration status. The law targeted anyone who had ever been deported or denied entry, regardless of their current legal status. This overbreadth was a central element of both the district court's and appellate court's analysis in blocking the law.
Part 3: Iowa's 287(g) network and enforcement infrastructure
Iowa State Patrol - Task Force Model
The Iowa State Patrol has a 287(g) agreement with ICE. As of September 2025, three Iowa State Patrol troopers had been trained and authorized under the Task Force Model, which authorizes officers to make immigration arrests during routine patrol activities - not only in jail settings. This means Iowa State Patrol officers conducting traffic enforcement on Iowa highways and roads have delegated authority to conduct immigration enforcement.
County and local agencies
Investigative reporting by Iowa Public Radio and The Midwest Newsroom found that as of September 2025, there were 34 total 287(g) agreements across Iowa, Kansas, Missouri, and Nebraska combined. Iowa's share included the state patrol and some county agencies. Cedar Rapids Police Department and Linn County Sheriff's Office did not have 287(g) agreements as of that reporting - notable because Cedar Rapids has the ICE Field Office. The enforcement posture varies significantly across Iowa's 99 counties. State law requires cooperation with ICE; whether and how counties formalize that cooperation through 287(g) varies.
ICE financial incentives - Task Force model pay structure
Beginning October 1, 2025, ICE began offering financial incentives to agencies participating in the Task Force Model 287(g): full reimbursement for the annual salary and benefits of each trained 287(g) officer, including overtime coverage up to 25% of annual salary, plus quarterly performance bonuses up to $1,000 per officer for locating undocumented immigrants and assisting ICE. ACLU of Nebraska described the bonus structure as creating a perverse incentive to prioritize immigration enforcement over local public safety needs.
Part 4: Iowa's agricultural and workforce context
Iowa's immigration landscape is defined in significant part by its agricultural and meatpacking economy. According to Common Good Iowa: more than half of all butchers and meat processors in Iowa are immigrants; one in four Iowa physicians are immigrants; one in five maids and housekeepers are immigrants. The meatpacking industry in Iowa has been a focal point of immigration enforcement for decades - from the 2008 Postville raid to current enforcement operations.
This economic reality creates the same tension visible in Idaho (dairy), Georgia (agriculture), and Indiana (agriculture): the enforcement machinery targets communities whose labor is essential to the state's economic base. Unlike Idaho, Iowa has not seen its own sheriffs' associations or law enforcement groups publicly oppose the enforcement model. The resistance to SF 2340 came primarily from the courts, immigrant advocacy organizations, and Democratic-aligned groups - not from the law enforcement establishment.
Part 5: What you can actually do in Iowa
SF 2340 is blocked - but ICE is not
The most important thing to understand about the Iowa framework is that the block on SF 2340 protects you from state prosecution for the state immigration crimes SF 2340 would have created. It does not protect you from federal ICE enforcement, which operates under federal law and which Iowa Code Chapter 27A requires local law enforcement to cooperate with. If you are arrested or detained by ICE in Iowa, it is a federal action - SF 2340's injunction is irrelevant to federal arrests.
The judicial warrant for home entry
The Fourth Amendment protection for your home is unchanged by any Iowa law. An administrative ICE warrant (Form I-200 or I-205) does not authorize forced entry into a private home without consent. A judicial warrant signed by a judge naming the specific address is required. Do not open the door without seeing a judicial warrant. State clearly through the closed door: 'I do not consent to entry. Please slide the warrant under the door.'
Know your right to remain silent
You have the right to remain silent in any law enforcement encounter - including with Iowa State Patrol officers who have 287(g) Task Force authority. You are not required to answer questions about your immigration status, country of birth, or how you entered the United States. State clearly: 'I am exercising my right to remain silent. I want to speak with a lawyer.' Iowa State Patrol troopers with Task Force Model authority can question you about immigration status and make civil immigration arrests during routine traffic stops.
Know that Iowa has mandatory ICE cooperation
Iowa Code Chapter 27A requires every Iowa law enforcement agency to cooperate with ICE. If you are arrested and booked into any Iowa county jail, the facility is required to cooperate with ICE detainer requests. There are no counties or cities in Iowa that have adopted policies limiting this cooperation. The TRUST Act-style protections that exist in Illinois, Connecticut, and other states do not exist in Iowa.
If someone is detained
Iowa's primary ICE detention facilities are in Polk County and surrounding areas; ICE also uses county jails under cooperation arrangements. Use the ICE Online Detainee Locator at locator.ice.gov immediately after any arrest. Call the ICE Detention Reporting and Information Line at 1-888-351-4024 if the person does not appear. Contact an immigration attorney immediately - bond hearings in Iowa move quickly.

Iowa requires full cooperation with federal immigration enforcement under Iowa Code Chapter 27A - no sanctuary policies exist at any level. SF 2340, which would have created state immigration crimes and arrest powers for state and local officers, was blocked by a federal district court in June 2024 and that block has been upheld twice by the Eighth Circuit (January 2025 and October 2025). As of mid-2026, SF 2340 remains blocked - verify current status at aclu-ia.org. The Iowa State Patrol has a 287(g) Task Force Model agreement. ICE operates independently of any state legislation and the block on SF 2340 does not stop federal immigration enforcement. Iowa's agricultural and meatpacking economy is heavily dependent on immigrant labor. The judicial warrant for home entry and the right to remain silent are the foundational constitutional protections.
This page reflects conditions as of mid-2026. Iowa Code Chapter 27A predates 2025 and is in full effect. SF 2340 was signed April 10, 2024; blocked June 17, 2024 (Judge Locher, S.D. Iowa); Eighth Circuit upheld injunction January 25, 2025 and October 23, 2025; litigation continues as Iowa Migrant Movement for Justice v. Bird; Iowa AG Brenna Bird continues to pursue enforcement. Iowa State Patrol 287(g) agreement in effect; three Iowa troopers trained under Task Force Model as of September 2025. ICE Task Force model financial incentives (salary reimbursement, $1,000/quarter bonus) began October 1, 2025. Cedar Rapids Police Department and Linn County Sheriff did not have 287(g) agreements as of September 2025 (Iowa Public Radio/Midwest Newsroom reporting).
