A Federal Judge Just Voided the Termination of Legal Status for 900,000 CBP One Migrants. What Happens Now?

On March 31, 2026, U.S. District Judge Allison Burroughs of the District of Massachusetts issued a ruling that struck at the center of the Trump administration's immigration enforcement strategy: the mass termination of humanitarian parole for migrants who had legally entered the United States through the Biden-era CBP One mobile application [1][2]. The decision orders the restoration of legal status for potentially hundreds of thousands of people — and sets the stage for a high-stakes appellate battle that could redefine the limits of executive discretion over parole.

What the CBP One Program Was — and What It Wasn't

The CBP One app launched in January 2023 as a scheduling tool that allowed migrants to book appointments at southern border ports of entry to present themselves for processing [3]. Rather than crossing illegally between ports, applicants submitted biometric data and underwent background checks before arriving. Upon presentation, the vast majority — around 96 percent, according to House Homeland Security Committee findings — were granted humanitarian parole under 8 U.S.C. § 1182(d)(5), which permits the Secretary of Homeland Security to parole individuals into the country "on a case-by-case basis for urgent humanitarian reasons or significant public benefit" [4][5].

That parole grant was not a visa. It was not a green card. It was a temporary authorization — typically lasting up to two years — that allowed individuals to remain in the United States, receive work permits, and pursue immigration proceedings, including asylum claims [6]. By the time the Trump administration took office in January 2025, more than 900,000 people had entered through the program [2][7].

The top countries of origin for CBP One entrants included Venezuela, Haiti, Cuba, Nicaragua, Honduras, El Salvador, Colombia, Mexico, Russia, Chile, and Guatemala [3][8].

The Mass Termination

Within hours of taking office in January 2025, the Trump administration shut down CBP One's appointment-scheduling function, cancelled existing appointments, and repurposed the app to facilitate voluntary departure [9]. Then, in April 2025, the Department of Homeland Security sent emails to approximately 900,000 recipients who had entered through the program, declaring "it is time" for them to "leave the United States" [1][2]. The notices terminated their parole status, revoked their work authorization, and placed them at risk of expedited removal — a fast-track deportation process that limits legal recourse to a single credible-fear interview [6][10].

DHS did not publicly disclose how many individuals received the April 2025 termination notice or how many had already been deported by the time of the March 2026 ruling [2][7]. Advocacy organizations reported widespread confusion, with some recipients unaware their parole had been terminated until employers flagged E-Verify status changes [10]. Immigration judges in some jurisdictions began denying or "pretermitting" asylum applications from former CBP One parolees without full hearings [10].

The Ruling: "Not in Accordance with Law"

Judge Burroughs found that the mass termination "exceeded the agency's statutory authority and contradicted the procedures set forth in its own regulations" [1][2]. The central holding: while the Secretary of Homeland Security has discretion to grant and terminate parole, that discretion is not unlimited. Federal regulations require individualized determinations — the same case-by-case standard that governs the initial parole grant also constrains its revocation [1].

"The regulations do not give the agency unfettered discretion to terminate parole," Burroughs wrote. "When Defendants terminated the impacted noncitizens' parole without observing the process mandated by statute and by their own regulations, they took action that was 'not in accordance with law'" [1][2].

The ruling relied on the Administrative Procedure Act (APA), which requires that federal agency actions conform to the procedures established by statute and regulation. By sending mass email terminations without individual review of each parolee's circumstances, DHS failed to follow its own rules — regardless of whether the underlying policy decision to end the program was within the executive's power [1][2].

The case was brought by Democracy Forward and the Massachusetts Law Reform Institute on behalf of affected migrants and the Venezuelan Association of Massachusetts [2][9].

The Steelman Case Against CBP One

The Trump administration's legal argument — and the position of several conservative legal organizations — is that the Biden administration itself acted unlawfully by creating the CBP One parole pipeline in the first place [4][5][11].

The statute, 8 U.S.C. § 1182(d)(5), specifies that parole may be granted "only on a case-by-case basis." The House Homeland Security Committee concluded that Secretary Mayorkas used parole "as a default tool to bring large populations of specific demographics into the United States" through categorical programs "never authorized by Congress" [4]. Former INS Commissioner Doris Meissner, who served under President Clinton, acknowledged the scale was "unprecedented" [4].

The Heritage Foundation characterized the CBP One program as allowing migrants to "schedule their illegal entry" via a phone application, arguing that Biden "perverted parole to invent a slew of 'McVisa' programs" that bypassed congressionally established numerical caps on immigration [11]. The Center for Immigration Studies has argued that categorical parole programs — those that grant parole to entire classes of people rather than assessing individual cases — are facially unlawful under the 1996 statutory amendments [5].

In the parallel CHNV (Cuban, Haitian, Nicaraguan, Venezuelan) parole litigation, the Fifth Circuit Court of Appeals wrote in Texas v. Biden that Mayorkas' mass parole was "the opposite of the 'case-by-case basis' determinations required by law" and violated "Congress's statutory commands" [4].

DHS spokesperson responded to the Burroughs ruling by calling it "blatant judicial activism undermining the President's Article II authority to determine who remains in this country," adding: "Under federal law, DHS had full authority to revoke parole. Canceling these paroles is a promise kept to the American people to secure our borders and protect our national security" [1][2].

Due Process and Circuit Court Precedent

The legal status conferred by CBP One approval — humanitarian parole — occupies an unusual position in immigration law. Parolees are technically "admitted" to the United States but have not been granted formal immigration status [6][10]. They receive a Notice to Appear in immigration court, which initiates removal proceedings and allows them to apply for asylum and other forms of relief [10].

The due process question turns on whether parole creates a liberty or property interest that the government cannot revoke without procedural protections. Judge Burroughs sidestepped the constitutional due process question by grounding her ruling in the APA and the agency's own regulatory framework — a narrower basis that avoids the harder constitutional question but achieves a similar result [1][2].

The ruling is consistent with a line of cases holding that when agencies establish procedural rules, they must follow them even if the underlying substantive decision is discretionary. This "agencies must follow their own rules" doctrine — rooted in cases like Accardi v. Shaughnessy (1954) — has been a recurring basis for judicial intervention in immigration cases [1].

The CHNV Precedent — and What It Signals for Appeal

The most relevant precedent is the litigation over the CHNV parole program, which allowed up to 30,000 nationals from Cuba, Haiti, Nicaragua, and Venezuela to enter the U.S. monthly with financial sponsors [12][13].

That case followed a similar trajectory: a district court in Massachusetts (Judge Indira Talwani) blocked the termination in April 2025 [12]. The First Circuit denied the government's emergency stay request in May 2025 [12]. But on May 30, 2025, the Supreme Court intervened on the shadow docket, issuing a 7-2 stay that allowed the termination to proceed while litigation continued [13][14]. Justices Jackson and Sotomayor dissented [13].

By September 2025, the First Circuit ruled that the administration's termination of CHNV parole was likely lawful, though the litigation continues in district court toward final judgment [12][14].

This timeline is instructive. Judge Burroughs' CBP One ruling will almost certainly be appealed to the First Circuit, where the government won on the CHNV question. The administration will likely seek an emergency stay — and if the First Circuit denies it, a Supreme Court shadow-docket intervention similar to the CHNV case is a realistic possibility [12][13][14].

The key legal distinction defenders of the CBP One ruling will draw: the CHNV case involved terminating a program, while this case involves terminating individual parole grants already made. Whether that distinction survives appellate review is an open question.

Who Is Affected — and Where

The approximately 900,000 CBP One entrants are dispersed across the United States, with significant concentrations in cities with established immigrant communities [3][8]. The top nationalities — Venezuelan, Haitian, Cuban, Honduran, Salvadoran, Colombian, and Mexican — map onto communities in South Florida, the New York metropolitan area, Texas border cities, and major metros like Chicago, Los Angeles, and Boston [3][8].

The lawsuit itself was filed in Massachusetts, where the Venezuelan Association of Massachusetts was a named plaintiff [2][9]. Organizations including Al Otro Lado, a legal aid nonprofit, and Lawyers for Civil Rights have been tracking affected individuals [8][15]. The International Rescue Committee, UNHCR, and Doctors Without Borders have documented conditions for migrants who remained in Mexican border cities during the original wait for CBP One appointments — a population that experienced a 70 percent increase in cases of sexual violence, according to Doctors Without Borders reporting [3].

Many CBP One parolees had, by the time of the termination notices, obtained other forms of legal protection — Temporary Protected Status (TPS), pending asylum applications, or active immigration court proceedings — that may insulate them from immediate removal regardless of the parole termination [7][10]. The precise number who had no alternative legal protection at the time of the ruling is unknown.

Enforcement: Can the Court Make It Stick?

If the ruling survives appeal, the enforcement question is real. Federal courts have limited tools to compel executive compliance with immigration orders, and the Trump administration has signaled willingness to resist judicial mandates in this area [1][2].

The primary enforcement mechanism is contempt of court. If DHS refuses to restore parole status as ordered, plaintiffs could seek contempt findings against named officials. But the practical logistics of "restoring" parole for hundreds of thousands of people — re-issuing work permits, updating immigration databases, notifying employers — are substantial [10].

The administration has precedent for slow-walking compliance with immigration court orders. In prior cases involving the Remain in Mexico policy and DACA, administrations of both parties have taken months or years to fully implement adverse court rulings, citing administrative complexity [6].

USCIS also granted arrest authority to its officers beginning October 2025, a significant expansion that could complicate restoration efforts if officers have already initiated enforcement actions against former parolees [10].

The Fiscal Picture

The costs of this legal and administrative upheaval are substantial on all sides.

The FY2026 DHS budget request of $191 billion — nearly double FY2024 levels — includes $45 billion for new immigration detention centers (a 265 percent annual increase to ICE's detention budget) and $29.9 billion for enforcement and deportation operations [16][17]. These figures reflect the administration's broader enforcement priorities, not CBP One-specific costs, but the population of former CBP One parolees is a significant component of the enforcement caseload.

The immigration court backlog already exceeded 3 million cases before the parole terminations added hundreds of thousands of potential new proceedings [18]. Congress capped immigration judges at 800, a number widely regarded as insufficient [18]. The Congressional Budget Office estimated that the immigration surge of 2022-2024 — which includes the CBP One population — would add $7 billion in federal costs over a decade, but also generate $1 trillion in additional revenue through taxes and economic activity [19].

The original CBP One processing infrastructure — the app, staffing at ports of entry, background check systems — was built at a fraction of the cost now allocated to enforcement. Whether mass re-detention and removal of a working, tax-paying population produces net fiscal benefits or net fiscal costs remains a contested empirical question.

What Comes Next

The immediate next steps are procedural. The Trump administration will appeal to the First Circuit, where the CHNV precedent favors the government. If the First Circuit reverses, the case likely ends there for practical purposes. If it affirms, a Supreme Court petition is near-certain — and the current Court's 7-2 stay in the CHNV case suggests the government would find a receptive audience [13][14].

In the meantime, the status of the roughly 900,000 affected individuals remains in limbo. Those with pending asylum cases, TPS, or other legal protections have some buffer. Those without alternative status face the prospect of arrest, detention, and expedited removal — or, if the ruling holds, a restoration of the parole they were initially granted [6][10].

Skye Perryman, president of Democracy Forward, called the ruling "a clear rejection of an administration that has tried to erase lawful status for hundreds of thousands of people with the click of a button" [2]. DHS maintains its actions were lawful and necessary. The federal courts will ultimately decide — but the human consequences for nearly a million people are already unfolding.
