What our own data shows (and its limit)

Only 3 courts in this dataset are explicitly named as detention facilities, and their grant rates span 12.8% to 53.3% - too small a sample, and too confounded by case mix and era, to establish the detention effect on its own.

That is exactly why the sections below cite TRAC and Vera Institute research built on much larger, purpose-collected samples, rather than extrapolate from 3 courts.

The Detention Disparity

Immigration detention status is one of the strongest predictors of case outcomes in the immigration court system. Detained respondents are less likely to be represented by an attorney, have less time to prepare their cases, and face courts that operate on accelerated timelines. The result is a measurable gap in grant rates between detained and non-detained populations.

This disparity has been documented by the American Immigration Lawyers Association, TRAC at Syracuse University, and numerous academic studies. The consistent finding is that detention itself, independent of the merits of the underlying claim, has a negative effect on outcomes. Respondents with identical claim profiles fare worse when detained than when allowed to pursue their cases from the community.

Access to Counsel

The representation gap is the primary mechanism through which detention affects outcomes. Detained individuals face severe barriers to finding legal help. Many detention facilities are in rural areas far from legal aid organizations and private immigration attorneys. Communication is restricted, phone calls are expensive and time-limited, internet access may be unavailable or restricted, and in-person attorney visits may be limited by facility rules. The result is that a large majority of detained respondents appear in court without an attorney.

Accelerated Timelines

Detained dockets move faster than non-detained dockets. While this reduces time spent in detention, it also reduces time available to prepare a claim. Asylum applicants may need to gather evidence from their home country, obtain expert declarations, secure translations of documents, and prepare detailed testimony. Doing this from detention, often without an attorney, in a matter of weeks is extremely challenging.

What the Data Shows on PlainImmigration

PlainImmigration's underlying EOIR extract does not carry a per-case detention-status field, so we cannot show a true detained-vs-non-detained grant-rate split - most courts hear a mix of both docket types with no flag distinguishing them. Only 3 courts in our data are explicitly named as detention facilities, and as the numbers above show, they do not move together (one well below the national average, two at or above it) - too small and too confounded by case mix, era, and court to isolate a detention effect on its own.

For the specific detained-vs-non-detained comparison, TRAC at Syracuse University and the Vera Institute of Justice publish periodically-updated detention outcome reports built on much larger, purpose-collected samples; we link to those primary sources rather than overstate what our own general EOIR extract can show. What we do show live is court-level and judge-level grant rates, which readers can use alongside that external research.

If You or a Family Member Is Detained

The detained docket moves on a compressed timeline, so acting quickly matters more than in a non-detained case. Contact an immigration attorney or an accredited representative immediately; EOIR maintains a list of free and low-cost legal service providers organized by detention facility. Ask whether bond is available, since release on bond (where granted) restores the time and access to evidence that a non-detained case allows. Gather any documents, witness contacts, and country-condition evidence as early as possible, ideally before the first master calendar hearing, because continuances are harder to obtain on detained dockets than on non-detained ones.

Key takeaways

Detained vs non-detained: what to remember

Detention is one of the strongest documented predictors of outcome in immigration court research - primarily through its effect on access to counsel and preparation time, not through the merits of the underlying claim.
Our own EOIR extract has no per-case detention-status field and only 3 explicitly-named detention-facility courts - too small a sample to prove the disparity on its own, which is exactly why we cite TRAC and Vera's larger, purpose-built studies instead of guessing from 3 courts.
If you or a family member is detained, speed matters more than in a non-detained case - contact an attorney or accredited representative immediately and ask about bond.
Release on bond, where granted, restores the time and access to evidence that a non-detained case allows - it does not resolve the case, but it changes the odds of preparing it well.
