TPS, Port Inspections, and Supreme Court Scrutiny: Three Immigration Law Facts in Focus

Three distinct threads of U.S. immigration law — Temporary Protected Status, port-of-entry asylum processing, and the ongoing Supreme Court litigation in Noem v. Al Otro Lado — are converging in federal dockets this term, and the underlying facts carry weight beyond the courtroom.

Congress enacted the Temporary Protected Status statute in 1990 as part of the Immigration Act, codifying a mechanism to shield nationals of designated countries from removal when conditions at home — armed conflict, environmental disaster, or other extraordinary circumstances — render return unsafe. The statutory framework grants the executive branch discretion to designate, extend, and terminate TPS for specific nationalities, a design that has made TPS the subject of repeated litigation over the scope of that discretion.

The population composition of current TPS holders matters to several pending legal arguments. Haitians constitute a larger TPS-protected population than Syrians, according to a brief filed in April 2026 in the consolidated Supreme Court cases bearing docket numbers 25-1083 and 25-1084. That demographic gap is relevant to proportionality arguments: when courts or policymakers assess the humanitarian and administrative consequences of termination decisions, the relative size of affected cohorts informs both the equitable calculus and the practical burden on immigration agencies.

The third data point comes from the merits briefing in Noem v. Al Otro Lado (No. 25-5). Respondents' brief, filed in February 2026, states that U.S. Customs and Border Protection officers at times permitted certain asylum seekers to cross the border for inspection at ports of entry during the period under review in the underlying Mullin v. Al Otro Lado litigation. That brief is significant because the government's ability — or willingness — to accommodate asylum seekers at designated ports goes to the heart of the legal dispute over "metering" and related access restrictions.

"Metering" refers to the CBP practice of limiting daily entries at ports and placing asylum seekers on waitlists managed by Mexican authorities, a policy that became widespread between roughly 2016 and 2020. Plaintiffs in Al Otro Lado argued that metering effectively turned ports into denial points rather than inspection points, violating the statutory right under 8 U.S.C. § 1158 to apply for asylum upon arrival in the United States. The respondents' concession — or acknowledgment — that CBP did sometimes permit crossings for inspection cuts in two directions: it supports the government's argument that ports remained nominally functional, but it also underscores that admission was discretionary and inconsistent rather than uniform.

Noem v. Al Otro Lado thus sits at the intersection of two foundational questions in asylum law: whether the government can restrict access to the asylum process at ports without triggering statutory or constitutional liability, and what remedial authority federal courts hold when agency conduct is found to have blocked that access. The case name reflects the substitution of Secretary Kristi Noem for her predecessor at the Department of Homeland Security — a routine caption change, not a shift in the government's legal position.

The TPS dockets (25-1083 and 25-1084) raise a separate but structurally related question: how much latitude the executive retains to reverse prior designations, and whether reliance interests built up over years — or decades — of TPS status constrain that reversal. The 1990 statute's silence on several procedural guardrails has left courts to construct doctrine largely from administrative law principles, particularly the arbitrary and capricious standard under the APA.

Taken together, these cases ask the Court to clarify the boundaries of executive discretion across two of immigration law's most politically exposed mechanisms. The factual record being assembled in the dockets — population sizes, CBP operational practices, the history of statutory interpretation — will shape not just the outcomes for current TPS holders and asylum seekers, but the doctrinal architecture that governs immigration enforcement for the foreseeable future.
