What is an ICE detainer and how does it work?
An immigration detainer is an administrative request issued by ICE under 8 C.F.R. §287.7. The current form — I-247A — is one of three primary detainer forms used since the program was restructured in 2017. The form asks a local law enforcement agency (LEA) to (1) notify ICE before releasing the subject and (2) maintain custody of the subject for up to 48 hours beyond the time the subject would otherwise be released — excluding weekends and holidays — so ICE can assume custody.
The 48-hour clock is the central operational detail. It begins running when the state would otherwise release the person — for example, when bond is posted, when charges are dismissed, when a sentence completes, or when the case ends in acquittal. The clock does not run while the person is held on state authority. A defendant who posts a $1,500 bond on a misdemeanor at 9:00 a.m. on Monday but has an active ICE detainer will not walk out the front door of the jail. The state release triggers ICE custody, and ICE has 48 hours (excluding weekends and federal holidays) to take physical custody.
Detainers are typically lodged after fingerprints are run through the FBI Integrated Automated Fingerprint Identification System and the matching IDENT/HART biometric system shared with the Department of Homeland Security. A "hit" — a record indicating prior immigration enforcement contact, a removal order, an immigration violation history, or even a prior visa overstay — triggers an ICE review. If the review identifies the person as removable, a detainer is sent to the jail electronically.
The Third Circuit's decision in Galarza v. Szalczyk, 745 F.3d 634 (3d Cir. 2014), is the leading appellate authority holding that ICE detainers issued under 8 C.F.R. §287.7 are permissive requests rather than mandatory orders. The Third Circuit reasoned that treating detainers as mandatory would violate the Tenth Amendment's anti-commandeering principle. As the court put it, the county was "free to disregard the ICE detainer." Despite this, Texas counties — operating under state law and county jail policies — have generally chosen to honor every detainer received. The federal-law point matters in §1983 litigation and in policy debate, but it does not currently produce release in Texas jails.
An ICE detainer — Form I-247 — is one of the most consequential pieces of paper a non-citizen can encounter in the Texas criminal justice system. The form is filed by Immigration and Customs Enforcement (ICE) with the county jail holding a person in state custody. It asks the jail to hold the person for up to 48 hours past the point of state release so federal agents can take custody for removal proceedings. It is not a judicial warrant. It is not signed by a federal judge. It is an administrative request — but in nearly every Texas county, it is treated as a mandatory hold.
L and L Law Group, PLLC defends non-citizens facing the intersection of Texas state criminal charges and federal immigration consequences across the nine DFW counties we serve: Collin, Dallas, Denton, Tarrant, Rockwall, Kaufman, Ellis, Johnson, and Hunt. Co-founding partners Reggie London and Njeri London — both licensed Texas attorneys since 2005 — handle each case personally. The decisions made in the first 24 hours of ICE custody — what charge to fight, what plea to avoid, when to seek bond, whether to file a habeas petition — frequently determine whether the client remains in the United States.
Why ICE detainers exploded after 2017 and what changed under the second Trump administration
Detainer practice has shifted dramatically since 2017. The 2017 Executive Order on Enhancing Public Safety in the Interior of the United States (EO 13768) directed DHS to prioritize the removal of all removable non-citizens with any criminal charge, dropping the prior administration's narrower focus on serious convictions. Under that order — and the ICE memoranda implementing it — detainers were issued more aggressively and across a broader range of cases.
The 2025 return of the Trump administration produced another acceleration. Executive actions issued in early 2025 directed DHS to expand §287(g) agreements, reinstate the Secure Communities biometric program, and remove prior limits on which non-citizens were prioritized for detention. Texas Governor Abbott's Operation Lone Star — running in parallel since 2021 — created an additional layer of state-level enforcement activity along the border that frequently produces state charges that trigger federal detainers once the person is booked.
The practical consequence for non-citizens in the DFW area: any state criminal contact — even a Class C municipal traffic citation that lands the person in jail because they could not post a small bond, even a misdemeanor family-violence allegation that ends in dismissal, even an arrest on a charge that is later no-billed by the grand jury — can produce a detainer. The detainer reaches the jail before the state case is resolved. By the time the state case ends in dismissal or acquittal, the person is already in federal custody and in removal proceedings.
This is the reason criminal-defense decisions for non-citizens cannot be made in isolation from immigration consequences. A misdemeanor plea that looks favorable on the state side — deferred adjudication on a marijuana possession, a no-contest to a Class B theft, a plea to disorderly conduct — can produce a deportation order under INA §237 even when the state case is never converted to a conviction for state purposes.
§287(g) and the Texas county map — which jails are deputized?
Section 287(g) of the Immigration and Nationality Act authorizes ICE to enter into written agreements with state and local law enforcement agencies that allow designated state and local officers to perform certain immigration enforcement functions. The §287(g) program has three primary models: the Jail Enforcement Model (JEM), the Warrant Service Officer (WSO) program, and the Task Force Model (which was restored in 2025 after being discontinued in 2012).
Texas has been the largest state participant in §287(g) for years. Multiple Texas counties — including counties in the DFW area and the broader North Texas region — operate under active §287(g) agreements. Where a county jail is deputized, jail staff can interview detainees about immigration status, access ICE databases, and serve immigration warrants directly. The practical effect is that immigration enforcement happens at booking rather than after a detainer is received.
Counties that do not have a §287(g) agreement still receive detainers through Secure Communities. Secure Communities is the biometric information sharing program that runs every arrest fingerprint through the DHS IDENT/HART database. The program was reinstated in 2017, suspended in 2021, and reinstated again in 2025. In Texas, the practical effect of Secure Communities is that every arrest in every county is screened against immigration databases within minutes of booking.
Texas Senate Bill 4 (SB 4) — enacted in 2017 and substantially expanded in 2023 — requires Texas law enforcement agencies to comply with ICE detainers and prohibits "sanctuary" policies that would limit cooperation with federal immigration enforcement. The Texas Attorney General has authority to enforce SB 4 against non-compliant agencies. The combination of SB 4 plus widespread §287(g) participation plus Secure Communities makes Texas one of the highest-enforcement environments for non-citizens in the United States.
The intersection with Texas state custody — how a detainer wrecks bond
From the moment a detainer is lodged, the criminal case develops on two parallel tracks: the state case proceeds in county or district court under Texas Code of Criminal Procedure, and the federal removal case develops in immigration court under the Immigration and Nationality Act. The two tracks are governed by different statutes, different judges, different procedural rules, and different burdens of proof. The decisions made on one track frequently determine outcomes on the other.
Bond is the first collision point. Under Texas Code of Criminal Procedure Article 17.15, the magistrate is required to consider community ties, criminal history, ability to make bail, and the nature of the offense when setting bond. None of those factors track whether the defendant has an ICE detainer. The magistrate may set a $500 personal bond on a misdemeanor and still see the defendant transferred directly to ICE custody once state release is processed. From the defense perspective, the family that pays a bondsman to post bond may be paying for a release that produces transfer to an ICE facility rather than release to home.
The strategic decision tree gets complicated. Sometimes the right move is to litigate the state case to dismissal first — to push for suppression, to attack the affidavit, to negotiate a no-bill from the grand jury — before attempting to resolve the federal side. Sometimes the right move is to address the federal piece first through a stay request, an Article 17.151 release on personal bond, or a bond hearing in immigration court. The sequencing depends on the facts of the case, the immigration history of the client, and the federal-state coordination at the specific jail.
Article 17.151 of the Code of Criminal Procedure — the 90-day release timer for felonies and 30-day timer for misdemeanors — applies to non-citizens the same way it applies to citizens. A defendant in custody on a felony for 90 days without the State being ready for trial is entitled to release on personal bond. The fact that an ICE detainer attaches does not extinguish the Article 17.151 right. But the practical effect — release from state custody into federal custody — needs to be accounted for in the strategic decision about whether to file the motion.
Federal removal consequences under INA §237 and §212
The Immigration and Nationality Act provides two parallel grounds for removal of non-citizens. Section 237 (8 U.S.C. §1227) governs deportability — it applies to non-citizens who are already admitted to the United States and have become removable because of post-admission conduct. Section 212 (8 U.S.C. §1182) governs inadmissibility — it applies at the border and to certain non-citizens applying for adjustment of status. The same criminal conduct can sometimes trigger both grounds, with different defenses available in each.
INA §237(a)(2)(A)(i) — Crimes Involving Moral Turpitude (CIMT). A non-citizen is deportable if convicted of a CIMT committed within five years after admission and for which a sentence of one year or longer may be imposed. Texas misdemeanor theft under Penal Code §31.03 is a CIMT. Misdemeanor assault with a family-violence finding is a CIMT for many purposes. Misdemeanor fraud and forgery are CIMTs. The five-year window matters: a misdemeanor theft committed six years after admission to lawful permanent resident status is not a §237(a)(2)(A)(i) deportable offense — though it may still create other immigration exposure.
INA §237(a)(2)(A)(ii) — Multiple CIMTs. Two CIMTs at any time after admission, not arising from a single scheme of criminal misconduct, render a non-citizen deportable regardless of the five-year window.
INA §237(a)(2)(A)(iii) — Aggravated felony. Conviction of an aggravated felony renders the non-citizen deportable and bars most forms of relief. The aggravated-felony list is defined in INA §101(a)(43) and is broader than the term suggests. A Texas misdemeanor theft can be an aggravated felony if the sentence imposed is one year or more — even if the sentence is suspended. A Texas state-jail felony for drug delivery is an aggravated felony. The aggravated-felony analysis is the most consequential immigration consequence and requires careful charge-by-charge review.
INA §237(a)(2)(B) — Controlled substance offenses. A conviction of any violation of any law relating to a controlled substance — other than a single offense involving possession for personal use of 30 grams or less of marijuana — is a deportable offense. Texas Penal Code §481.115 (possession of a controlled substance), §481.121 (marijuana possession), and §481.112 (delivery of a controlled substance) all trigger this provision. The small-marijuana exception does not extend to other substances and does not extend to delivery offenses.
INA §237(a)(2)(E) — Domestic violence, stalking, child abuse. A non-citizen is deportable if convicted of a crime of domestic violence, stalking, or child abuse — including a violation of a protective order under INA §237(a)(2)(E)(ii). Texas Penal Code §22.01(b)(2) family-violence assault and §25.07 violation of a protective order both trigger this provision. The family-violence finding under Texas Code of Criminal Procedure Article 42.013 is independently consequential for immigration purposes even where the underlying offense level is a misdemeanor.
Padilla v. Kentucky, 559 U.S. 356 (2010). The Supreme Court held that the Sixth Amendment right to effective assistance of counsel requires criminal-defense attorneys to advise non-citizen clients about the deportation risks of a guilty plea. Where the law is clear that a particular plea will result in deportation, counsel must affirmatively advise of that consequence. Where the law is ambiguous, counsel must advise that there is a risk of removal. A failure to do so can be grounds for post-conviction relief.
What family members must do in the first 24 hours
The first 24 hours after ICE custody begins are the highest-leverage window for family action. Decisions made in that window — what jail to call, what documents to collect, whether to give consent for searches, whether to talk to ICE officers, whether to retain counsel before the state arraignment — frequently determine outcomes that play out over the following months.
(1) Locate the detained person. The ICE Online Detainee Locator System (ODLS) at locator.ice.gov tracks people in ICE custody by name and country of birth or by A-number. Family members who do not know the A-number can search by name plus country. The system updates within a few hours of detention. If the person is still in state custody and has not yet been transferred to ICE, the county sheriff's inmate lookup will show them.
(2) Gather immigration documents immediately. Lawful permanent resident card (green card), employment authorization document (EAD), visa, passport, I-94 entry record, prior immigration court documents, prior criminal records, marriage certificates, birth certificates of U.S.-citizen family members. These documents will be required for any application for cancellation of removal, adjustment of status, asylum, or withholding. They should be located, copied, and centralized while the detained person is in custody and cannot collect them.
(3) Do not let the detained person speak to ICE without counsel. ICE officers interview detainees routinely. The interviews are not Mirandized in the criminal-procedural sense — Miranda applies to criminal interrogation, and immigration enforcement is technically civil. But statements made to ICE are admissible in removal proceedings and can establish or defeat eligibility for relief. The detained person should decline all interviews until counsel is engaged. The right phrase is: "I want to speak with my lawyer before I answer any questions."
(4) Retain dual-track counsel. The state criminal case and the federal removal case require coordinated representation. Some firms handle only the state side. Some immigration firms handle only the removal side. The non-citizen client benefits most from coordinated representation that tracks both tracks and aligns plea strategy with immigration relief strategy. L and L Law Group handles the state side and coordinates with immigration counsel on the federal side.
(5) Consider an immigration bond. Most detained non-citizens are eligible for an immigration bond after the initial mandatory-custody period ends. Bond is set by the immigration judge under 8 C.F.R. §1003.19. The standard is whether the detained person is a flight risk or a danger to the community. Mandatory detention under INA §236(c) applies to specific categories — including aggravated felons and certain other enumerated offenses — and removes the bond option in those cases. The detention center where the person is held determines which immigration court will hear the bond request.
Common ICE detainer scenarios — and the defense response
Scenario 1: First-time misdemeanor arrest, LPR client. The client is a lawful permanent resident with no prior criminal history. They are arrested on a misdemeanor — a DWI, a theft, a marijuana possession. A detainer lands within hours. The state case is defensible. The right move is typically to litigate the state case aggressively — push for dismissal through suppression or pretrial intervention — and to avoid any plea that would trigger §237. A no-billed grand jury or a dismissed-after-pretrial-intervention outcome lets the LPR avoid removal exposure entirely.
Scenario 2: Family-violence allegation, undocumented client. The client is undocumented. The allegation is a misdemeanor §22.01(b)(2) assault with a family-violence finding. A detainer lands. The family-violence finding under Texas CCP Article 42.013 will independently trigger §237(a)(2)(E) — even if the underlying offense is a misdemeanor with a deferred adjudication on the state side. The defense strategy must avoid a family-violence finding, either by plea to a non-family-violence offense (disorderly conduct, simple assault without finding) or by trial.
Scenario 3: State-jail felony drug delivery. The client is charged with delivery of a controlled substance under Texas Penal Code §481.112 — a state-jail felony if Penalty Group 1 and under one gram, a higher felony for larger amounts. Delivery is an aggravated felony for INA purposes under §101(a)(43)(B). The state plea must be analyzed in light of the aggravated-felony bar. Pleading to simple possession instead of delivery is a classic immigration-conscious plea negotiation. The state-jail-felony exposure matters less than the categorical aggravated-felony exposure.
Scenario 4: Dismissed state case, detainer remains. The state case is dismissed. The grand jury no-bills. The State files a motion to dismiss for insufficient evidence. The detainer remains, and the client is transferred to ICE custody. The state case is over but the removal case continues. The strategy shifts entirely to the federal side — bond hearing, relief analysis, removal defense.
Why direct-attorney representation matters in ICE detainer cases
Detainer cases stack three independent layers of decision-making — the state criminal case, the federal removal case, and the time-sensitive bond and detention questions that overlay both. Coordination matters. A plea that looks defensible on the state side can foreclose immigration relief on the federal side. A detention strategy that succeeds on the state side can leave the client in federal custody for months.
