Mandatory Immigration Detention Under INA § 236(c): The Threshold Questions That Control Bond Eligibility

Review the primary official source.

A label of “mandatory detention” does not end the analysis. Counsel should identify the source of custody authority, the exact criminal disposition or alleged conduct, the statutory subparagraph invoked, and the procedural path for challenging classification. Those threshold questions determine whether an immigration judge may consider bond and whether another forum may review continued custody.

Identify the actual detention statute

Obtain the custody determination, NTA, Form I-286, criminal records, prior orders, parole or admission documents, and any DHS explanation. Section 1226 generally governs detention pending a decision on removal, while sections 1225 and 1231 can govern different postures. The same person may move between statutory frameworks as the case changes.

Do not infer authority only from the facility, charge, or length of custody. Record the government’s stated statute and compare it with the pending proceedings, finality of any order, and current relief or judicial-review posture.

Match the asserted trigger to the record of conviction

Section 1226(c) cross-references specified criminal and security grounds. Obtain certified charging documents, plea and judgment records, sentence information, custody and release dates, and the statute in effect. Arrest narratives and rap sheets may omit the elements or final disposition.

Analyze whether the offense and record actually fit the invoked ground. Categorical-approach questions, sentence rules, admissions, and conduct-based provisions should not be blended together. The government’s classification can be challenged without conceding removability.

Separate classification review from discretionary bond

Immigration regulations provide a custody-redetermination process and identify limits on immigration-judge authority. A threshold request may contest whether section 1226(c) applies; a discretionary bond request addresses danger, flight risk, and conditions of release if the judge has authority.

Prepare both records when appropriate. The classification packet needs statutes, dispositions, custody history, and legal analysis. The release packet needs a sponsor, address, identity proof, court-attendance history, rehabilitation, medical needs, family support, and feasible conditions.

Evaluate prolonged-detention and habeas questions

Even when the government invokes mandatory detention, prolonged custody can raise separate statutory and constitutional questions. The relevant law depends on the detention statute, procedural history, circuit, duration, reasons for delay, and process already provided.

Maintain a custody chronology showing arrest, transfers, hearings, continuances, appeals, government requests, respondent requests, and expected next steps. Habeas relief is case specific and does not replace the immigration merits process.

What this means: practical action checklist

• Confirm the current custody statute and proceeding posture.
• Obtain certified dispositions and release records.
• Match the alleged trigger to the exact statutory subparagraph.
• Prepare threshold classification and discretionary-release records separately.
• Maintain a complete detention and delay chronology for possible federal review.
