Why It Matters

A new Congressional Research Service report published on June 9 lays bare a legal crisis at the heart of the Trump administration's immigration enforcement strategy: whether the government can lock up undocumented immigrants already living in the United States, without any opportunity for a bond hearing, while their deportation cases wind through the courts.

The circuit split immigration detention dispute turns on a single phrase in federal law. Under 8 U.S.C. § 1225(b)(2)(A), the government must detain any alien "seeking admission" who cannot prove beyond a doubt they are entitled to enter. The administration says that it covers everyone who entered the country illegally, no matter how long ago or how far from the border they were picked up. Three federal appeals courts say it does not.

The Big Picture

The legal framework governing detention during deportation dates to the Illegal Immigration Reform and Immigrant Responsibility Act of 1996, which created two parallel tracks. Under 8 U.S.C. § 1226(a), DHS has discretionary authority to detain or release someone on bond during removal proceedings. Under § 1225(b)(2)(A), certain "applicants for admission" must be detained with no bond option at all.

For nearly 30 years, the government treated those two categories differently. People who entered without inspection and were living in the interior were generally eligible for bond hearings under the discretionary track. Arriving aliens caught at ports of entry were not.

That changed in July 2025. ICE issued interim guidance declaring that both groups, arriving aliens and those who entered without inspection, are "applicants for admission" under the statute and therefore subject to mandatory detention during removal proceedings, with no bond hearings permitted.

Customs and Border Protection issued similar guidance days later. In September 2025, the Board of Immigration Appeals formalized the shift in a precedential ruling, Matter of Yajure Hurtado, holding that a Venezuelan national who had lived in the United States for nearly three years was subject to mandatory detention regardless of how long he had resided here.

The administration's legal theory is straightforward: because federal statute defines "applicants for admission" to include both arriving aliens and those present without lawful admission, both groups are necessarily "seeking admission" and therefore covered by the mandatory detention provision. The Fifth Circuit has agreed, reasoning that there is no meaningful distinction between "applying for" and "seeking" something, and that decades of contrary executive practice cannot override the statute's plain text.

But the Second, Sixth, and Eleventh Circuits have all ruled the opposite way, each concluding that "seeking admission" requires actively pursuing lawful entry through inspection at a port of entry. The Second Circuit went further, warning that even if the statute were ambiguous, "the fact that the Executive Branch has for nearly three decades acted inconsistently with the newfound interpretation strongly counsels against adopting it." Both the Second and Sixth Circuits also upheld lower court findings that mandatory detention without bond hearings for people already residing in the country raises serious constitutional due process concerns.

The Laken Riley Act, signed in early 2025, added another wrinkle. That law amended a separate mandatory detention provision, 8 U.S.C. § 1226(c), to require detention of unlawfully present aliens who commit certain crimes. The Second and Eleventh Circuits used that amendment against the administration, reasoning that if § 1225(b)(2)(A) already required mandatory detention of everyone who entered without inspection, the Laken Riley Act's new mandatory detention category would be redundant. The Fifth and Eighth Circuits rejected that logic, arguing the two provisions cover different populations and serve different purposes.

Political Stakes

For the administration, the stakes are existential to a core enforcement promise. The policy of eliminating bond hearings for the interior undocumented population is central to the argument that the government can dramatically accelerate removals by keeping people detained throughout their proceedings, rather than releasing them and hoping they appear for court dates. A definitive legal loss would force a return to individualized bond hearings for a large share of the detainee population, straining immigration court capacity and undercutting the administration's narrative of enforcement without exception.

For congressional Republicans, the circuit split creates both a vulnerability and an opportunity. The Detention Authority Clarification Act (S. 4593), introduced in the 119th Congress, would resolve the dispute legislatively by explicitly codifying that aliens present without admission are subject to mandatory detention. Passing that bill would insulate the policy from further judicial challenge and hand the administration a durable win. Failing to act leaves the policy dependent on a Supreme Court that has not yet agreed to take up the question.

For Democrats, the circuit court immigration rulings offer a litigation roadmap. Three circuits have now handed them substantive legal victories, and the constitutional due process arguments that succeeded in the Second and Sixth Circuits provide a basis for continued challenges in jurisdictions where the law remains unsettled. Bills introduced in the 119th Congress, including the Dignity for Detained Immigrants Act (H.R. 6397 / S. 3702), would go further, striking the mandatory detention language from § 1225(b)(2)(A) entirely and requiring bond hearings for any alien detained by DHS.

For the public, the practical consequence is that legal rights during immigration removal proceedings currently vary by geography. An undocumented immigrant arrested in Texas falls under the Fifth Circuit and has no right to a bond hearing. The same person, arrested in New York, falls under the Second Circuit and does.

The Bottom Line

The CRS report identifies a question that has been building since July 2025 and now has no clean legal answer: can the Trump administration eliminate bond hearings for the entire interior undocumented population by reinterpreting a 1996 statute that courts have read differently for three decades?

The Supreme Court addressed mandatory detention in immigration removal proceedings in Jennings v. Rodriguez in 2018, holding that detention under § 1225(b)(2)(A) is mandatory until proceedings conclude. But the Court explicitly declined to decide whether that provision covers people already living in the United States, leaving the central question unanswered. With the Second, Sixth, and Eleventh Circuits now directly at odds with the Fifth and Eighth, the conditions for Supreme Court review are in place.

Until that happens, or until Congress acts, the mandatory detention policy the administration has staked significant enforcement credibility on will remain enforceable in some parts of the country and blocked in others.
