When ICE detains a loved one, families need answers: Why are they being held? Can they ask for bond? How long can they remain in custody? If there are reasons to believe the detention is unlawful, one tool we can evaluate is habeas corpus.
A habeas corpus petition asks a federal judge to examine whether the government has legal authority to keep someone detained. The central question is straightforward: What authorizes this continued detention?
In our practice, we have seen five types of cases that call for careful review.
1. The legal basis for the arrest is unclear
We begin by piecing together what happened: whether ICE had a warrant, what kind of warrant it was, how the arrest took place, and what documents ICE issued to justify detention. Knowing that an arrest occurred is only the starting point; we need to identify the legal authority for the arrest and for keeping the person in custody.
2. ICE says there is no opportunity to seek bond
In some cases, ICE maintains that detention is mandatory and that the person cannot request bond. This can happen even when someone is arrested inside the country years after entering.
We can ask a federal judge to examine whether ICE is applying the correct detention law. Depending on the facts and applicable law, we may seek release or a custody hearing before a decision-maker with authority to order release.
3. Detention drags on while the immigration case proceeds
When immigration proceedings become lengthy, we review how long the person has been detained, why the case has been delayed, and whether the person has had a meaningful opportunity to show that they can pursue their case while out of custody.
The passage of time alone does not guarantee release. The length of detention must be assessed alongside the circumstances of the case and the governing court decisions.
4. An ICE check-in ends in a new detention
Some people who were living in the community under an order of supervision are detained again when they attend an ICE appointment. In these cases, we examine whether the government explained its reasons, followed the required procedures, and took the person’s history of compliance into account.
5. There is a final removal order, but detention continues
When someone remains detained for a long time after receiving a final removal order, we investigate whether removal is actually possible in the reasonably foreseeable future and what legal basis exists for continued custody. A final order does not, by itself, answer every question about the lawfulness of prolonged detention.
What can we ask the judge to do?
The remedy depends on the facts, the stage of the immigration proceedings, and the laws and court decisions that govern where the petition is filed. Depending on the case, we may request:
- immediate release;
- a custody review that complies with the law; or
- an urgent government response, accompanied by the documents supporting detention.
Habeas corpus addresses detention. On its own, it does not cancel a removal order or grant immigration status. That is why a strategy for challenging custody must be coordinated with the defense of the immigration case.
The first step: review the record and act promptly
Families can help by gathering immigration documents, ICE notices, court orders, and the dates of arrests, hearings, and supervision appointments. This information helps us determine what is happening and assess whether a federal court petition is appropriate.
Every detention has its own history. A timely review makes it possible to make informed decisions and seek the appropriate remedy.
