Kansas Immigration: State Rules vs. Federal Law - and What to Do Here

This article reflects Kansas law as of June 2026. The central state law is Senate Substitute for House Bill 2372 (S Sub HB 2372), enacted April 10, 2026, after the Kansas Legislature overrode Gov. Laura Kelly's veto. It is in effect. The Kansas Bureau of Investigation's 287(g) Task Force Model agreement with ICE took effect February 18, 2025. Wyandotte County's Safe and Welcoming City Act (enacted February 2022, codified at Chapter 18 Sections 18-162 through 18-168 of the Unified Government Code) remains on the books; whether HB 2372 has altered its practical effect is a live question - verify current status with the ACLU of Kansas at aclukansas.org. Laws and enforcement patterns change quickly. Consult a licensed immigration attorney for advice specific to your situation.

Where Kansas Stands

Kansas occupies a distinctive position in this series as a veto-override state. Democratic Governor Laura Kelly moved twice to limit aggressive immigration enforcement legislation, and twice the Republican-controlled Legislature overrode her. The result is a state that has layered significant new enforcement infrastructure on top of an already active 287(g) foundation, while simultaneously containing one of the handful of local jurisdictions in the Great Plains - Wyandotte County - that has tried to limit local cooperation with ICE.

The 2025-2026 legislative period produced a sharper enforcement posture than most Kansans expected. The Kansas Bureau of Investigation became only the second state-level law enforcement agency in the country to sign a 287(g) Task Force agreement with ICE, giving KBI agents limited authority to make immigration arrests. Then HB 2372 removed the county commission oversight requirement for sheriff-ICE partnerships, statutory-authorized civil detainer holds, and created a 25-foot criminal buffer zone around law enforcement operations - including ICE operations. Kansas is now enforcement-aligned at the state level, with a meaningful internal exception at the county seat of Kansas City, Kansas.

The editorial heart of this Kansas article is the veto override story. It explains why enforcement is accelerating here - and it gives families the specific county-by-county and industry-by-industry information they need to understand what risk looks like on the ground in their part of the state.

Part 1: What Federal Immigration Law Actually Says

Immigration enforcement is exclusively a federal function. The Immigration and Nationality Act (INA) gives the federal government authority to regulate who may enter, remain in, and be removed from the United States. State and local governments cannot create their own immigration enforcement schemes that conflict with that framework.

The Tenth Amendment anti-commandeering doctrine limits what the federal government can demand of states. Printz v. United States (1997) established that the federal government cannot compel state or local law enforcement to administer or enforce a federal regulatory program. This is the legal foundation for why state and local cooperation with ICE is and must remain voluntary. Kansas cannot be forced to cooperate with ICE, and individual sheriffs cannot be forced by the state to cooperate if the federal government is the one doing the forcing. What the state legislature can do - and what HB 2372 does - is authorize and remove obstacles to voluntary cooperation at the local level.

Section 287(g) of the INA is the mechanism through which ICE formally delegates immigration enforcement authority to state and local agencies. Agencies that sign 287(g) agreements receive ICE training and acquire limited authority to perform certain immigration enforcement functions. Participation is voluntary, and the agreements operate under federal supervision and oversight. HB 2372 made it easier for Kansas sheriffs to enter these agreements by removing the county commission approval requirement that previously existed under state law.

ICE detainers - Form I-247 - are requests, not court orders. When ICE asks a county jail to hold someone beyond their scheduled release date so ICE can take custody, that is an administrative request signed by an immigration official, not a judicial warrant. Multiple federal circuit courts have held that honoring a civil detainer without a judicial warrant may expose the holding agency to Fourth Amendment liability. HB 2372 specifically addresses this by authorizing sheriffs to honor facially sufficient detainers under Kansas law, but the federal constitutional question remains an active one in the courts. A facially sufficient detainer under HB 2372 is one that clearly identifies the individual, has the probable cause or transfer-of-custody section completed, and is signed by a federal immigration official.

Arizona v. United States (2012) is the controlling Supreme Court precedent on state immigration enforcement. The Court struck down most of Arizona's SB 1070, holding that the federal government has broad and preemptive authority over immigration. States may not impose their own enforcement requirements or penalties on conduct regulated by the INA. What Kansas has done with HB 2372 is authorize and streamline voluntary cooperation - which is constitutionally permissible - rather than mandate enforcement of its own immigration law, which would not be.

Part 2: Kansas State Law

Kansas has built its enforcement framework through a combination of administrative action, legislative enactment, and veto override.

The KBI 287(g) Task Force Agreement - February 18, 2025

On February 18, 2025, the Kansas Bureau of Investigation, acting at the direction of Attorney General Kris Kobach, became the second state-level law enforcement agency in the country to enter into a 287(g) Task Force Model agreement with ICE under the second Trump administration. Under the agreement, a limited number of KBI agents received ICE training and were authorized to serve administrative warrants for immigration violations and to work with ICE on targeted arrests.

The KBI used the agreement for its first enforcement operation between October 24 and November 14, 2025, during which agents working in Hutchinson, Newton, Garden City, and Dodge City located and transferred to ICE custody 10 individuals with criminal records, including individuals appearing on sex offender, drug offender, and violent offender registries. KBI Director Tony Mattivi described the program's scope as focused on people with criminal histories. AG Kobach stated publicly that the KBI would not pursue immigration arrests against noncitizens not involved in criminal activity, though agents may make immigration arrests during drug operations in collaboration with ICE.

The mandatory cooperation bill introduced the same session - SB 178, which would have required all local law enforcement agencies to cooperate with ICE - failed after two canceled hearings and was not enacted. Law enforcement associations pushed back against the mandate, and the bill died in committee. The voluntary architecture of the current system means agency participation beyond KBI is a local decision, which is why the county-by-county picture matters.

S Sub HB 2372 - Enacted April 10, 2026 (Veto Override)

Senate Substitute for House Bill 2372 is the most significant piece of Kansas immigration legislation in the 2025-2026 session. Gov. Laura Kelly vetoed it on April 8, 2026, citing three concerns: First Amendment tensions from the 25-foot buffer zone provision, redundancy with existing federal law covering interference with federal law enforcement, and increased liability and costs for Kansas counties while removing local control over sheriff-ICE partnerships.

The Legislature overrode the veto on April 9, 2026. The House vote was 85-38 and the Senate vote was 31-9, both meeting the two-thirds threshold required for override. The bill became law April 10, 2026.

HB 2372 does several distinct things. First, it removes the previous requirement that county commissions approve a sheriff's participation in an agreement with an outside entity such as ICE. This was a meaningful check: Douglas County Sheriff Jay Armbrister had cited the commission oversight requirement as a reason he had not signed a 287(g) agreement. HB 2372 means sheriffs can now enter 287(g) partnerships without county commission approval.

Second, HB 2372 authorizes Kansas sheriffs to honor facially sufficient ICE detainer requests and to hold individuals for transfer to ICE custody, even without criminal charges. A detainer is facially sufficient if it clearly identifies the person, has the probable cause section or transfer-of-custody section completed, and is signed by a federal immigration official. The law also provides some minor safeguards: individuals must be released if the detainer is found insufficient, canceled, or if the person provides proof of citizenship or lawful status.

Third, HB 2372 includes what Senate President Ty Masterson referred to as the HALO Act: a provision creating a 25-foot criminal buffer zone around law enforcement and emergency personnel, including ICE agents, after a warning is given. The provision was framed as a public safety measure to prevent interference with law enforcement operations. The ACLU of Kansas identified First Amendment concerns with this provision and noted it raises questions about the right to observe and record law enforcement activity.

Fourth, HB 2372 provides an affirmative defense for law enforcement officers who cooperate with ICE. This gives participating agencies and officers legal protection against claims arising from immigration enforcement actions.

The ACLU of Kansas called HB 2372 a sweeping measure that allows sheriffs to enter harmful agreements with federal immigration authorities without local oversight, validates detainer requests without requiring a judicial warrant, and places financial liability on Kansas taxpayers in cases of officer misconduct leading to lawsuits. The civil liberties organization also noted the bill did not include the 48-hour detention limit that had appeared in a companion bill, HB 2771.

County 287(g) Agreements - 18+ Counties as of Late 2025

As of November 2025, 18 Kansas county sheriffs had signed 287(g) agreements with ICE under one of three models: the Jail Enforcement Model (jail staff screen individuals for immigration status), the Task Force Model (trained officers work alongside ICE agents in the community), and the Warrant Service Officer Model (officers are authorized to execute ICE administrative warrants). The 18 counties with agreements as of that time include Reno, Cowley, Rice, Wabaunsee, Anderson, Haskell, Franklin, Jewell, Rush, Ellis, Rooks, Saline, Brown, Sedgwick, Cloud, Lyon, Osage, and Phillips counties.

Shawnee County (Topeka), which covers the state capital, signed a Task Force Model agreement in July 2025, with six deputies receiving training. The Coffeyville, Wathena, and Caney police departments have also signed Task Force agreements. Pottawatomie County signed a Warrant Service Officer agreement in February 2026. Reporting in early 2026 noted that 76 agencies across Kansas and Missouri combined had Task Force agreements, suggesting the number in Kansas alone continues to grow.

ICE has offered financial incentives for participation, including up to $100,000 for vehicles and $6,500 per officer for equipment, which has made participation more attractive for smaller county sheriffs with limited resources.

Finney County and Southwest Kansas

Southwest Kansas, and Finney County in particular, represents a notable geography in this series. Garden City, the Finney County seat, has a census-estimated noncitizen population of around 13 percent, concentrated in the meatpacking and agricultural industries. The Finney County Sheriff signed a Warrant Service Officer model 287(g) agreement, the most limited of the three models, authorizing deputies to execute ICE administrative warrants. Sheriff Steve Martinez has stated publicly that local law enforcement relies on community trust and did not want people afraid to call for help.

ICE activity was reported in southwest Kansas in early 2025, producing visible fear in agricultural communities where workers, families, and employers are closely connected. Advocates described a marked shift in community atmosphere following enforcement operations. The meatpacking concentration in the area - Garden City, Dodge City, Liberal - creates a particular vulnerability given that food-processing workplaces have historically been targeted in large-scale ICE operations.

Wyandotte County: The Safe and Welcoming City Act

Wyandotte County (Kansas City, Kansas) adopted the Safe and Welcoming City Act in February 2022 by a 6-4 commission vote. The ordinance, codified at Chapter 18 Sections 18-162 through 18-168 of the Unified Government Code, established a municipal photo ID program for residents without government-issued identification and directed local law enforcement not to assist ICE investigations unless necessary to protect public safety or a judicial warrant was involved. The Wyandotte County District Attorney endorsed the measure at the time.

Whether HB 2372 has altered the legal footing of the Wyandotte ordinance is a question worth tracking. HB 2372 authorizes sheriffs to honor detainers and enter 287(g) partnerships without county commission oversight, but the Wyandotte ordinance governs the city police department and local government resources, not necessarily the county sheriff's office, which had a separate carve-out under the original ordinance. The ACLU of Kansas is the appropriate source to verify current status at aclukansas.org.

Douglas County

Douglas County (Lawrence) is home to the University of Kansas. The Douglas County Sheriff's Office stated in January 2025 that it would not proactively seek people for ICE and would follow the law. Sheriff Jay Armbrister had previously cited the county commission oversight requirement as a reason for not signing a 287(g) agreement. With HB 2372 eliminating that requirement, whether Douglas County's posture changes is a live question for families in that community.

Kansas City International Airport

Kansas City International Airport has played a growing role in deportation flight operations. ICE Air Operations has used KCI for both direct deportation flights to the U.S.-Mexico border and domestic shuffle flights that move detainees between detention facilities. Reporting from April 2026 documented 130 ICE Air departures from KCI during 2025 and 33 in the first quarter of 2026. This logistical infrastructure is relevant context for families whose detained loved ones may be moved through KCI.

Part 3: How State and Federal Law Interact in Kansas

Kansas state law, through HB 2372, reinforces federal immigration enforcement in several meaningful ways. It removes administrative barriers to voluntary 287(g) participation, gives sheriffs statutory authority to honor ICE detainers under state law, and provides legal protections for officers who cooperate with ICE. This puts Kansas in the category of states that have used state law to facilitate and encourage federal enforcement rather than limit it.

At the same time, the Kansas framework remains constitutionally anchored in voluntariness. The KBI 287(g) agreement is voluntary. Sheriff 287(g) agreements are voluntary. HB 2372 authorizes but does not mandate cooperation. The mandatory cooperation bill introduced by AG Kobach - SB 178 - failed in 2025. This matters because the Tenth Amendment anti-commandeering doctrine limits how far Kansas can push mandatory local enforcement, and that limit was tested and held during the 2025 session.

The civil detainer question is where the constitutional tension is most live. HB 2372 authorizes Kansas sheriffs to honor facially sufficient detainers and hold individuals without criminal charges. Federal circuit courts have found that honoring detainers without judicial authorization may violate the Fourth Amendment. HB 2372's authorization under state law does not resolve that federal constitutional question - it may simply mean Kansas counties bear more liability exposure when detainee challenges reach federal court. The ACLU of Kansas specifically flagged this risk in its 2026 legislative summary.

Wyandotte County's Safe and Welcoming City Act sits in legal tension with the state's enforcement direction. The ordinance restricts local government cooperation with ICE, while HB 2372 removes one of the key state-level restraints on that cooperation. Whether HB 2372 preempts or otherwise displaces the Wyandotte ordinance has not been definitively resolved. Families in Kansas City, Kansas should consult the ACLU of Kansas for current status.

Arizona v. United States (2012) is the ceiling on what Kansas can do. The Court's holding that immigration enforcement is exclusively federal means Kansas cannot create an independent immigration enforcement scheme. HB 2372 works within that constraint by framing itself as authorization and facilitation of federal enforcement, not a parallel state enforcement system. However, the detainer hold authority and the HALO Act buffer zone are provisions that advocacy organizations believe push against the constitutional boundary, and litigation remains a possibility.

Part 4: What This Means for Families on the Ground

For immigrant families in Kansas, the practical picture has shifted materially since early 2025.

In counties with 287(g) Jail Enforcement Model agreements, anyone booked into county jail - for any reason, including minor offenses - may be screened for immigration status. A traffic stop that leads to a jail booking can result in an ICE detainer. This is the most common pathway from ordinary law enforcement contact to immigration detention in Kansas.

In counties with Task Force Model agreements, trained deputies can work alongside ICE agents in the community, making arrests outside the jail context. This means immigration arrests can happen at workplaces, during traffic stops, or in neighborhoods - not only when someone is booked into jail. Shawnee County (Topeka) and several individual cities operate under this model.

In southwest Kansas, the meatpacking communities around Garden City and Dodge City face elevated risk. Workplace enforcement operations in food processing have occurred historically and are plausible in the current enforcement environment. Community advocates in those areas have urged families to make preparedness plans regardless of their immigration status, because mixed-status households face disruption even when the targeted person is a family member rather than the individual themselves.

Families should understand that ICE enforcement operations in Kansas are being routed through KCI for deportation flights. Someone detained in Wichita, Topeka, or Garden City may be moved to KCI for a deportation flight on short notice. If your family member is detained, use the ICE Detainee Locator immediately: locator.ice.gov. Detainees can be moved quickly, and locating them early is critical.

The HALO Act 25-foot buffer zone is also relevant for family members and community observers. Under HB 2372, approaching within 25 feet of law enforcement - including ICE agents - after being warned to stay back is a criminal offense. If you are witnessing an enforcement action involving a family member, understand that you have a right to observe and record from a safe distance, but the 25-foot buffer applies after a warning. The ACLU of Kansas has flagged First Amendment concerns with this provision. Observe from a distance, document carefully, and do not physically intervene.

In Douglas County (Lawrence), the sheriff's stated posture as of early 2025 was not to proactively seek people for ICE. Whether that posture has changed following HB 2372 is something families in that area should monitor through local reporting and the ACLU of Kansas.

In Wyandotte County (Kansas City, Kansas), the Safe and Welcoming City Act ordinance remains on the books, directing city police not to assist ICE investigations absent public safety necessity or a judicial warrant. The practical effect of HB 2372 on that ordinance is not fully resolved. Families in KCK should contact the ACLU of Kansas or Kansas Appleseed for current guidance.

Part 5: What You Can Actually Do

This section applies to every family in Kansas regardless of where in the state you live.

If ICE Comes to Your Home

Do not open the door. ICE cannot legally enter a home without a judicial warrant signed by a judge. An ICE administrative warrant - Form I-200 (Warrant for Arrest of Alien) or Form I-205 (Warrant of Removal/Deportation) - is not a judicial warrant. It is signed by an immigration officer, not a judge, and does not give ICE the right to enter your home. Slide the warrant under the door or ask to see it through a window. If there is no judicial warrant, you may say through the closed door that you do not consent to entry.

You have the right to remain silent. You are not required to answer questions about where you were born, how you entered the country, or your immigration status. This right applies to everyone regardless of immigration status. You may say: 'I am exercising my right to remain silent. I want to speak with a lawyer.'

Do not sign anything. Do not sign any documents without first speaking with an immigration attorney. Signing voluntary departure or other removal documents can waive important legal rights.

If ICE stops you in public, you have the same right to remain silent. Stay calm. Do not run. Do not physically resist. Clearly state that you are exercising your right to remain silent and that you want to speak with a lawyer. Ask if you are free to go. If they say yes, leave calmly.

If a Family Member Is Detained

Use the ICE Online Detainee Locator at locator.ice.gov immediately. You will need the person's country of birth and either their full name and date of birth, or their A-Number (Alien Registration Number). Detainees can be transferred to different facilities quickly, including through KCI for deportation flights. Locating your family member early is the most important first step.

Call the ICE Detention Reporting and Information Line: 1-888-351-4024.

Call the EOIR Immigration Court Information Line: 1-800-898-7180. This line provides information about immigration court hearing dates and case status.

Contact an immigration attorney immediately. In Kansas, immigration attorney Michael Sharma-Crawford's firm in Kansas City has worked on habeas petitions in Kansas cases. Kansas Appleseed and the ACLU of Kansas can help connect you with legal resources.

Know the Risk Points in Kansas

The jail pipeline is the primary risk pathway in counties with Jail Enforcement Model 287(g) agreements. Any arrest - for any offense - that leads to a county jail booking can result in an immigration detainer. Counties with Jail Enforcement agreements include Sedgwick (Wichita), Reno, Saline, and others. In these counties, a DUI, a traffic violation that results in booking, or any arrest can trigger the immigration screening process.

Traffic stops are a secondary risk point in counties with Task Force Model agreements, such as Shawnee County. If a deputy with Task Force training makes a traffic stop and develops a basis for an immigration arrest, that can happen in the field rather than only at the jail.

Workplace enforcement is a specific risk in southwest Kansas agricultural and meatpacking communities. Large-scale workplace operations have occurred in Kansas historically and are consistent with current federal enforcement priorities.

The 25-foot HALO Act buffer zone is a new legal risk for community members observing enforcement operations. Stay back, document from a safe distance, and do not physically intervene.

Summary

Kansas is an enforcement-aligned state as of June 2026. S Sub HB 2372, enacted by veto override on April 10, 2026, removed county commission oversight of sheriff-ICE partnerships, authorized civil detainer holds under state law, created a 25-foot criminal buffer zone around law enforcement operations including ICE, and gave cooperating officers an affirmative defense. The Kansas Bureau of Investigation signed the nation's second state-level 287(g) Task Force agreement in February 2025. More than 18 county sheriffs and several police departments hold 287(g) agreements.

The state framework is voluntary in structure: no mandatory cooperation law passed, and individual agencies retain discretion. Wyandotte County (Kansas City, Kansas) has a conflicting local ordinance - the Safe and Welcoming City Act - though its practical effect under HB 2372 is a live question. Southwest Kansas meatpacking communities face elevated industry-specific risk. KCI is an active deportation flight hub.

Immigrant families in Kansas should make preparedness plans, understand the legal limits on ICE home entry (no judicial warrant, no entry), exercise the right to remain silent, and use the ICE Detainee Locator immediately if a family member is taken into custody. Verification of current local law enforcement postures should go through the ACLU of Kansas at aclukansas.org.
