If ICE has issued a Form I-247A immigration detainer against you or someone in your family, the response to an ICE detainer (Form I-247A) comes down to three things: contact an immigration attorney immediately, know that the local jail is only authorized to hold the person for up to 48 hours beyond their normal release time, and write down the exact moment that release would have happened. The detainer is a request from ICE asking the jail to keep the person in custody so federal agents can pick them up for removal proceedings.1U.S. Immigration and Customs Enforcement. Immigration Detainer – Notice of Action Whether the jail actually honors it depends on where you are.
What the Detainer Asks the Jail to Do
Form I-247A makes two requests of the local facility. First, notify ICE before releasing the person, ideally at least 48 hours in advance if possible. Second, hold the person for up to 48 additional hours past the time they would otherwise walk out, so ICE has a window to take custody.1U.S. Immigration and Customs Enforcement. Immigration Detainer – Notice of Action
That 48-hour clock is not straight calendar time. The form and the underlying regulation at 8 CFR 287.7(d) exclude Saturdays, Sundays, and federal holidays.2eCFR. 8 CFR 287.7 – Detainer Provisions Under Section 287(d)(3) of the Act The clock starts when the person would have been released — bond posted, charges dropped, sentence complete, or a judge ordering release. Someone whose case resolves on a Friday evening could be held through the weekend and then 48 business hours into the next week. A holiday weekend stretches it further.
The form is explicit that the jail “is not authorized to hold the subject beyond these 48 hours.”1U.S. Immigration and Customs Enforcement. Immigration Detainer – Notice of Action If ICE does not arrive within the window, the person is supposed to be released.
Whether the Jail Has to Honor It
Federal courts have ruled that ICE detainers are requests, not commands. In Galarza v. Szalczyk, the Third Circuit held that 8 CFR 287.7 “does not compel state or local LEAs to detain suspected aliens subject to removal” and “merely authorizes the issuance of detainers as requests.”3Justia Law. Galarza v Szalczyk, No 12-3991 (3d Cir 2014) The regulation itself calls the detainer “a request that such agency advise the Department, prior to release of the alien, in order for the Department to assume custody.”2eCFR. 8 CFR 287.7 – Detainer Provisions Under Section 287(d)(3) of the Act
Another decision, Miranda-Olivares v. Clackamas County, found that holding someone past their release date based only on an ICE detainer, without independent probable cause or a judicial warrant, is an unreasonable seizure under the Fourth Amendment. The county was held liable. Because the local agency, not ICE, carries that risk, many jurisdictions have adopted policies limiting detainer compliance. Some refuse to hold anyone without a judicial warrant. Others simply decline to notify ICE of release dates. What this means for the person in custody: whether the detainer actually results in extended detention depends heavily on the county or state.
What to Do in the First Hours
Immigration proceedings are civil, not criminal, so the government does not appoint an attorney. You have to find one. Detained individuals have the right to receive visits from a lawyer, and many legal aid organizations run hotlines and referral lines for exactly this situation.
Ask the jail for a copy of the Form I-247A. The facility is supposed to serve it on the person named, and it includes a “Notice to the Detainee” section that explains why ICE has requested extended custody.4U.S. Immigration and Customs Enforcement. ICE Detainers – Frequently Asked Questions Written materials are generally supposed to be available in Spanish, and where practicable in other languages spoken by significant groups at the facility; oral interpretation is expected where written translation is not available.5U.S. Immigration and Customs Enforcement. ERO Language Access Information Practice varies by facility, so if the notice was not served, note that.
Record the exact time the person would have been released from criminal custody. That timestamp is the anchor for everything that follows: it starts the 48-hour clock, it tells you when the authorized hold ends, and it is the evidence you need if the jail keeps holding the person after the window closes.
The Notice to the Detainee lists the ICE Joint Intake Center at 1-877-2INTAKE (877-246-8253) for complaints.1U.S. Immigration and Customs Enforcement. Immigration Detainer – Notice of Action ICE’s Office of Professional Responsibility also takes calls at 1-833-4ICE-OPR for misconduct or civil rights concerns.
Ways to Challenge Continued Detention
An attorney will evaluate several options, but the main ones are these.
- Bond hearing. In many cases a detained person can request a bond hearing before an immigration judge, who decides whether release on bond is appropriate while the immigration case proceeds. ICE may argue flight risk or danger; the person has a chance to present evidence for release.
- Habeas corpus petition. If the detention itself is unlawful, for example if the 48-hour window has expired and the jail is still holding the person, or if ICE lacks a valid basis for the detainer, a habeas petition in federal court can challenge the government’s authority to continue the detention.
- Consular notification. A person in custody has the right to contact their country’s consulate. Consulates can sometimes help connect people with legal resources or intervene. Jails are supposed to keep a list of consulate phone numbers available to detainees.
When the 48 Hours Run Out
The 48-hour limit is a hard ceiling. If ICE has not taken custody and the jail continues holding the person, the extra time may be unlawful detention. This is the point at which the timestamp you wrote down becomes critical evidence, and it is when a habeas petition or a call to a civil rights attorney becomes urgent.2eCFR. 8 CFR 287.7 – Detainer Provisions Under Section 287(d)(3) of the Act Remember that Saturdays, Sundays, and federal holidays are excluded from the count, so calculate carefully or ask an attorney to do it.
If ICE does take custody within the window, the person moves into federal immigration detention and the case shifts into removal proceedings, where the bond hearing and other options above become the path forward.
The Current Federal Landscape
The federal government has been increasing pressure on jurisdictions that limit detainer compliance. A January 2025 executive order, “Protecting the American People Against Invasion,” directed DHS to expand 287(g) agreements that deputize local officers for immigration functions, and directed the Attorney General to pursue enforcement against jurisdictions seen as interfering with federal immigration law.6Congress.gov. Recent White House Actions on Immigration An April 2025 order, “Protecting American Communities from Criminal Aliens,” instructed agencies to identify federal grants and contracts flowing to sanctuary jurisdictions for possible suspension.7The White House. Protecting American Communities from Criminal Aliens
Both orders emphasize compliance with 8 U.S.C. §§ 1373 and 1644, which generally bar state and local governments from restricting employees’ sharing of immigration-related information with federal authorities.6Congress.gov. Recent White House Actions on Immigration Information sharing is a different question from physically holding someone on a detainer, and several of these federal funding threats are being litigated. Local practice on detainers is shifting, sometimes rapidly, which is another reason to talk to a local immigration attorney who knows what the county jail is actually doing right now rather than relying on what its written policy said last year.
