What Happens at the Jail Door on Release

The handover from a county jail to a federal facility follows a fixed order. Prints go out at booking, a match returns, a request reaches the jail, criminal authority ends, and a short window opens during which a transfer can be arranged. Each step has its own timing, and counsel who knows the order can predict the day the client disappears from the county roster.

The fingerprint match at booking

Booking prints are submitted to federal criminal history systems as a matter of routine, and from there they are checked against immigration records. Nothing about that submission depends on the arresting officer, the charge, or any request from a prosecutor. It happens for every person booked at a facility that participates, which is nearly all of them, and it happens within hours rather than days.

A match returns when the prints correspond to an existing immigration record: a prior encounter, an application, an admission, a previous removal. The absence of a match is not proof of citizenship and its presence is not proof of removability. It is an indication that a record exists, which is enough to prompt a review by an officer who then decides whether to send anything to the jail.

That review is where the client's history matters more than the pending charge. A person with a prior removal order, a prior encounter at the border, or an earlier conviction in one of the enumerated categories draws attention that a person with a clean record and a lawful admission may not. Counsel who takes the immigration history at the first interview can usually predict the outcome of the review before it happens.

The request lodged with the jail

What arrives at the jail is a form addressed to the facility. It identifies the person, recites the basis on which the agency believes removability may exist, and asks two things: notification before the person is released, and continued custody for a short period so that transfer can be arranged. It is directed at the custodian, not at the defendant, and it creates no obligation the defendant can discharge.

The form is a request rather than a command, and jurisdictions differ sharply in what they do with it. That difference, and the litigation behind it, is treated separately in what a detainer does to a criminal case calendar. For the purpose of predicting a release, what matters is narrower: whether this facility, on this day, honors requests as a matter of standing policy.

How long a facility may hold on the request

The regulation asks the receiving facility to maintain custody for a period not to exceed forty-eight hours, excluding Saturdays, Sundays and holidays, beyond the time the person would otherwise have been released. Two features of that formula matter in practice. The clock starts at the end of criminal authority, not at the moment the request arrived. And the exclusions can stretch two days into four when a release falls late in the week.

The period is a ceiling on what the agency asks for, not a grant of authority to the jail. Where a facility holds beyond it, or holds when its own jurisdiction has told it not to, the exposure is the jurisdiction's rather than the federal agency's. Several jurisdictions have restricted the practice for exactly that reason, and others require a judicial warrant before any additional custody.

The window closes quietly. If no officer arrives before it expires, the person is released, and the request remains on the file against a future encounter. Counsel should treat an expired window as a reprieve rather than a resolution, because the underlying record has not changed.

Offenses that make a hold near certain

The offense categories that draw a request are the same ones the deportability statute names, which is why charge selection in the criminal case controls so much of what follows. A controlled substance count other than a single small marijuana possession, a firearm offense, an offense with a domestic violence finding, and anything falling within the aggravated felony list all draw attention reliably, and the sorting of those categories is worked through in which offenses carry the aggravated felony label.

The pattern behind the table is worth stating plainly. Where the offense appears by name in the statute, the request follows from the charge. Where it depends on a sentence figure or on an element that may or may not be in the final conviction, the criminal disposition still controls the answer, and the specific problem of a weapon allegation is taken up in how firearm offenses create removability.

The transfer and what counsel should record

The transfer itself is unremarkable. Officers attend the facility, the person is signed over, and a vehicle leaves. Destination is a function of bed space, so a client booked in one county may be processed in another and held in a third, sometimes hundreds of miles away. Nobody in the criminal case is notified as a matter of course, and the first sign is often a missed setting.

Three pieces of information should go into the file the same day: the date of transfer, the receiving facility, and the identification number assigned on intake. Without the number, mail does not arrive and telephone accounts cannot be funded; without the facility, the criminal court cannot arrange production. Where the client's exposure is serious, counsel will also want lawyers who act when custody is transferred engaged early, since the custody question in that forum moves faster than the criminal calendar does.

Counsel should also assume the client will be interviewed. Statements made during intake processing can be used later, and a client who has been told nothing will answer questions about place of birth, entry and residence because the questions seem administrative. A short conversation before release, covering what will be asked and what the client is not obliged to volunteer, is the single most useful preparation available, and it matters most where the charge carries a domestic relationship, as discussed in domestic violence findings and protective orders.
