Mandatory Detention

Mandatory detention refers to the legal requirement under Section 1226(c) of the Immigration and Nationality Act that certain noncitizens, particularly those with specified criminal convictions, be held in custody without the possibility of release on bond while their removal proceedings are pending. The provision removes the discretion immigration judges typically have to consider release.

When the law requires no bond.

It's a rule that says some immigrants with certain criminal records must stay locked up — no bond, no release — until their deportation case is finished.

Simple example
Under Section 1226(c), a lawful permanent resident with a qualifying drug conviction can be detained by ICE upon release from criminal custody and held without a bond hearing throughout removal proceedings.
Why it matters
What the term actually changes.
Public Safety Argument

Supporters argue mandatory detention ensures that noncitizens with criminal records do not abscond or commit new offenses before their cases are resolved. They view it as a tool Congress chose to enforce immigration law consistently.

Length Of Confinement

Critics note that removal cases can stretch from months to over a year, meaning some detainees remain confined for long periods without an individualized hearing on whether detention is necessary in their case.

How it works
The mechanics, in practice.
Triggering Convictions

The statute lists categories of offenses — including certain drug crimes, aggravated felonies and crimes involving moral turpitude — that trigger mandatory detention once a noncitizen is taken into immigration custody.

No Bond Review

Unlike other detainees, those held under Section 1226(c) generally cannot ask an immigration judge for release on bond. Courts are now weighing whether prolonged detention under this rule requires constitutional safeguards.
