When ICE tells a person or family that detention is “mandatory,” that does not end the legal analysis. The critical question is which federal detention statute actually applies. Depending on the person’s immigration history, manner of entry, criminal case, procedural posture, and whether a final removal order exists, mandatory ICE detention New York may fall under 8 U.S.C. § 1225, § 1226(a), § 1226(c), or § 1231.
Those distinctions matter because they can determine whether an immigration judge has bond authority and whether federal court review may be available.
For people detained in New York, recent Second Circuit litigation has made this issue especially important. A habeas petition under 28 U.S.C. § 2241 may, in an appropriate case, challenge the statutory or constitutional basis for detention.
This article provides general legal information, not legal advice for any particular case. Counsel must review each case because small factual differences can change the detention analysis.
What Does mandatory ICE detention New York Actually Mean?
Mandatory ICE detention means federal law requires detention without the ordinary discretionary bond process if the person falls within a specific statutory detention category.
The phrase can be misleading because not everyone ICE detains without bond is necessarily subject to the same statute.
Some people are detained under 8 U.S.C. § 1226(a), which generally permits discretionary detention or release while removal proceedings are pending. Others may be detained under § 1226(c), which contains mandatory-detention provisions for specified categories of noncitizens.
Still others may be detained under § 1225, which concerns applicants for admission and certain inspection-related cases, or under § 1231 after a final removal order.
That is why the first question should not simply be, “Did ICE deny bond?”
The more useful question is:
What statute gives the government authority to detain this person right now?
Which Federal Immigration Detention Statute Applies?
The applicable detention statute depends on the person’s immigration status, manner of entry, criminal history, and stage of the removal process.
A simplified comparison looks like this:
| Statute | General Context | Bond Issue |
| 8 U.S.C. § 1225 | Certain applicants for admission and inspection-related detention | Immigration-judge bond jurisdiction may be unavailable |
| 8 U.S.C. § 1226(a) | Pre-removal-order detention | Discretionary release or bond may be available |
| 8 U.S.C. § 1226(c) | Specified mandatory-detention categories | Ordinary discretionary bond generally unavailable while the statute applies |
| 8 U.S.C. § 1231 | Detention connected to a final removal order | Different post-order detention rules apply |
This classification is not merely technical. It can determine who has authority to review custody, what hearings are available, and what arguments can be raised in federal court.
Section 1226(a): Discretionary Detention
Section 1226(a) generally authorizes the government to arrest and detain a noncitizen while a removal decision is pending, but it also authorizes release on bond or conditional parole.
When § 1226(a) applies, the central issue may be whether the person can obtain a custody redetermination before an immigration judge.
Section 1226(c): Mandatory Detention
Section 1226(c) identifies categories Congress has placed into mandatory custody.
Criminal history is often central, but the analysis should not stop at the words “criminal case” or “conviction.” Counsel may need to examine the exact criminal statute, disposition, sentence, charging documents, and immigration allegations.
The Laken Riley Act, enacted in 2025, also expanded federal mandatory-detention provisions. As a result, older online explanations of § 1226(c) may no longer capture every current detention category.
Does Every Criminal Case Make ICE Detention Mandatory?
No. A criminal arrest, charge, or conviction does not automatically make every person subject to mandatory immigration detention.
Whether § 1226(c) applies can require a detailed comparison between the immigration statute and the person’s criminal record.
Relevant records may include:
- criminal complaints and indictments;
- certificates of disposition;
- plea and sentencing records;
- immigration charging documents;
- records showing the government’s claimed ground of removability; and
- evidence that charges were dismissed, reduced, or otherwise changed.
The distinction can be significant.
For example, in Hanson v. Joyce, a 2026 case in the Southern District of New York, the court addressed a situation in which relevant criminal charges had been dismissed. The court concluded that, under the circumstances, § 1226(c) no longer provided the governing detention authority and ordered a bond hearing.
The lesson is not that dismissal always guarantees bond. Detention authority can depend on the current facts rather than the label ICE originally placed on the case.
What Is a Joseph Hearing in a Mandatory-Detention Case?
A Joseph hearing allows a person detained under § 1226(c) to contest whether the government has properly placed that person within the mandatory-detention category.
The procedure comes from Matter of Joseph, a Board of Immigration Appeals decision.
A Joseph hearing is different from an ordinary bond hearing. The threshold issue is whether the mandatory-detention statute properly applies.
That distinction matters because someone detained under § 1226(a) may have access to discretionary custody review that is generally unavailable to someone properly detained under § 1226(c).
A lawyer evaluating this issue may need to analyze both immigration law and the underlying New York or other state criminal statute. This is one reason crimmigration cases require individualized review rather than assumptions based solely on an arrest record or offense name.
Why Does the Difference Between Section 1225 and Section 1226 Matter in New York?
The distinction between § 1225 and § 1226 can determine whether an immigration judge has authority to consider bond.
This issue has generated major litigation involving people who entered the United States without inspection but later lived in the country for substantial periods before being detained.
In Barbosa da Cunha v. Freden, the U.S. Court of Appeals for the Second Circuit addressed whether the individual before it was properly treated as someone “seeking admission” and detained under § 1225(b)(2)(A).
The Second Circuit concluded that § 1226, rather than § 1225, governed that individual’s detention.
That holding has been particularly important in New York because Second Circuit decisions govern federal courts within the circuit.
The Board of Immigration Appeals, however, has taken a different approach in Matter of Yajure Hurtado, holding that immigration judges lack bond authority over certain people it considers detained under § 1225(b)(2)(A).
The resulting conflict helps explain why federal habeas review can become important: the dispute may concern not simply whether someone deserves bond, but whether the government selected the correct detention statute in the first place.
Has the Supreme Court Agreed to Review the Section 1225 Versus Section 1226 Dispute?
Yes. On October 1, 2026, the U.S. Supreme Court granted review in Rhoney v. Barbosa da Cunha, a case involving the detention-statute dispute.
Granting certiorari does not reverse the Second Circuit’s decision or decide the merits.
It means the Supreme Court has agreed to consider the legal issue.
For New York detainees and their families, this development makes current legal advice particularly important. Attorneys handling detention cases should monitor the Supreme Court proceeding because the eventual decision could affect how § 1225 and § 1226 are interpreted.
A legal article discussing this issue should therefore be read with its publication and update date in mind.

Can a Habeas Petition Challenge Mandatory ICE Detention?
Yes. A federal habeas petition may challenge the legal or constitutional basis for immigration detention when the circumstances support such a claim.
Under 28 U.S.C. § 2241, federal courts may consider habeas claims alleging custody in violation of federal law or the Constitution.
In an immigration-detention case, habeas arguments can take different forms.
Challenging the Statutory Basis for Detention
One type of challenge argues that ICE is detaining the person under the wrong statute.
For example, the legal question might be whether § 1225 actually governs the person’s custody or whether the case instead falls under § 1226.
Similarly, a case labeled mandatory under § 1226(c) may require analysis of whether the statutory conditions for mandatory detention are actually satisfied.
This is fundamentally different from asking a judge to decide whether the person is dangerous or likely to appear for future hearings.
Challenging Prolonged Detention
A different habeas theory concerns whether detention has become constitutionally problematic because of its duration and surrounding circumstances.
A prolonged-detention claim should not be confused with a wrong-statute claim.
No sound basis exists to reduce every habeas case to a universal rule such as “wait six months and file.” The legal analysis depends on the governing statute, controlling precedent, procedural history, reasons for delay, and other case-specific circumstances.
Is Filing Habeas the Same as Asking an Immigration Judge for Bond?
No. A federal habeas petition and an immigration-court bond proceeding involve different courts, different legal questions, and potentially different remedies.
An immigration judge generally applies the custody authority under immigration statutes and regulations.
A habeas petition is filed in federal district court and can ask whether detention itself complies with federal statutory or constitutional requirements.
Depending on the case, a federal court might address whether the government is using the correct detention statute, whether procedural protections are constitutionally required, or whether another custody-related legal defect exists.
A favorable habeas ruling does not necessarily mean immediate release.
In some cases, the remedy may instead be an individualized bond hearing or another custody proceeding conducted under the proper legal standard.
What Documents Should Be Reviewed Before Accepting ICE’s Claim of Mandatory Detention?
A lawyer should review the immigration, criminal, and detention records before concluding that ICE is legally required to hold someone without bond.
Important documents may include:
- the Notice to Appear;
- ICE custody paperwork;
- immigration-court bond or custody decisions;
- records concerning entry, inspection, parole, or release;
- criminal complaints, indictments, and accusatory instruments;
- certified criminal dispositions;
- plea and sentencing records;
- prior immigration decisions;
- any final removal order; and
- records showing where the person is currently detained.
Timing also matters.
A person may have been placed into custody based on circumstances that later changed. Criminal charges may be dismissed. Removal proceedings may move to a different procedural stage. A final removal order may be entered.
Each development can require a fresh analysis of which detention statute currently governs.
What Should a Family Ask When ICE Says There Is No Bond?
Families should ask why ICE believes bond is legally unavailable and what statute the government says authorizes detention.
Useful questions for counsel include:
- Is ICE relying on § 1225, § 1226(a), § 1226(c), or § 1231?
- Does the person’s criminal record actually satisfy the claimed mandatory-detention provision?
- Is a Joseph hearing available?
- Does the immigration judge have jurisdiction to conduct a bond hearing?
- Has anything changed since ICE first classified the person as mandatorily detained?
- Is there a viable federal habeas argument challenging the statutory basis or duration of detention?
These questions help separate a difficult detention case from one in which the government’s legal premise may itself be contestable.
Conclusion: What Should You Know About Challenging Mandatory ICE Detention in New York?
Evaluate an ICE statement that detention is “mandatory” against the federal statute governing the person’s custody.
For someone detained in New York, determining whether § 1225, § 1226(a), § 1226(c), or § 1231 applies can affect bond jurisdiction, available hearings, and the possibility of federal habeas review.
Recent Second Circuit litigation—and the Supreme Court’s October 1, 2026 decision to review the § 1225 versus § 1226 dispute—makes careful, current analysis especially important.

FAQ: What Questions Do People Ask About Mandatory ICE Detention in New York?
Does ICE calling detention “mandatory” prevent a federal court from reviewing it?
No. Depending on the case, a federal court hearing a habeas petition may consider whether the government is detaining the person under the proper statutory authority or whether the detention violates federal law or constitutional protections.
Can dismissed criminal charges change whether detention is mandatory?
Yes, they can affect the analysis in some cases. The result depends on the statute ICE is invoking, the nature of the original allegations, the final disposition, and the person’s broader immigration circumstances.
Can a federal judge order an ICE bond hearing?
A federal court may order a bond hearing in an appropriate habeas case, but that remedy is not automatic. Available relief depends on the established legal violation and the controlling law.
Does the Supreme Court’s review of Rhoney v. Barbosa da Cunha immediately change New York detention law?
No. The Supreme Court’s October 1, 2026 grant of review means the Court has agreed to hear the dispute; it has not decided the merits. Monitor the case because the eventual ruling may affect the interpretation of §§ 1225 and 1226.
What happens if an immigration judge says it lacks jurisdiction to grant bond?
The next step depends on why the immigration judge believes it lacks jurisdiction to grant bond. Counsel may need to evaluate administrative remedies, whether the governing detention statute has been correctly identified, and whether federal habeas review is appropriate.
Is habeas only for people who have already been detained for many months?
No. Prolonged detention is one possible basis for habeas litigation, but it is not the only one. A habeas petition may also raise a threshold statutory challenge arguing that ICE is relying on the wrong legal authority for detention.
