Mandatory Detention During Removal

Proceedings: Circuit Split



June   9, 2026

The Department of Homeland  Security (DHS) may arrest and detain aliens for immigration status
violations that render them removable. While the agency generally has discretion to release aliens from
custody during the pendency of their removal proceedings, some categories of aliens must be detained.
Under 8 U.S.C. § 1225(b)(2)(A), ifan immigration officer determines that an individual is an applicant
for admission who is seeking admission into the United States and is not clearly and beyond a doubt
entitled to be admitted, the alien shall be detained during the removal proceedings. Federal statute
expressly states that aliens who are either arriving in the United States or present in the country without
lawful admission shall be treated as applicants for admission, but federal law does not define seeking
admission.
In 2025, it was reported that the Trump Administration issued interim guidance determining that
unlawfully present aliens found in the United States-including some who may have been present in the
country for several years-are subject to mandatory detention under § 1225(b)(2)(A). This interpretation
has resulted in numerous legal challenges by aliens present in the United States without having been
admitted, who have been detained and, as a result of the interim guidance, are no longer eligible for a
custody determination or release during their removal proceedings before an immigration judge. They
argue that they are not subject to mandatory detention under § 1225(b)(2)(A) because they were not
actively seeking admission into the United States. In the ensuing litigation, there has been a growing
circuit split in the federal courts of appeals over whether § 1225(b)(2)(A) applies strictly to aliens actively
seeking legal admission at the border or whether it also covers aliens present anywhere in the United
States who have not been lawfully admitted.


Statutory Background

The current statutory framework governing the detention of aliens placed in removal proceedings was
established by the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA).
Generally, under 8 U.S.C. § 1226(a), DHS has the discretion to detain an alien pending the outcome of
removal proceedings or it may release the alien on bond or the alien's own recognizance subject to
specified conditions (conditional parole). In this circumstance, ifthe agency determines that the alien
