Supreme Court Rules Migrants at the Border on Mexican Soil Have Not "Arrived" in the U.S. and Cannot Apply for Asylum
By 6-3, the Court in Mullin v. Al Otro Lado interpreted the Immigration and Nationality Act to permit "metering," letting border officers block asylum seekers before they set foot on U.S. soil.
Summary
On June 25, 2026, the U.S. Supreme Court ruled 6-3 that a migrant standing on the Mexican side of the border who is turned away before crossing has not "arrived in the United States" under federal immigration law, and so has no statutory right to be inspected or to apply for asylum [1][2][3]. Justice Samuel Alito wrote the majority opinion; the three liberal justices dissented, with Justice Sonia Sotomayor reading her dissent aloud from the bench [3][4]. The decision reverses a Ninth Circuit ruling that had found the practice known as "metering" — in which officers at ports of entry physically block asylum seekers from setting foot on U.S. soil — to be unlawful [1][5].
The legal fight turns on a few words in the Immigration and Nationality Act. The majority reads "arrives in the United States" to require physical presence inside the country, pointing to Congress's choice of that phrase and to a general presumption that U.S. laws do not apply abroad [1][7]. The dissent counters that since 1917 the law has required officers to inspect noncitizens who present themselves at ports of entry, and warns that letting officers stand at the line and physically block people lets the government evade that duty [4][5].
The ruling clears the way for the Trump administration to revive metering, a policy that began in late 2016 and expanded sharply in 2018, though the government had formally ended it in 2021 [1][5][15]. Supporters call it a lawful tool to manage limited processing capacity at crowded ports; critics say it strands people fleeing danger in Mexican border cities and pushes them toward more perilous illegal crossings [6][14]. The single sharpest dispute is whether physically blocking someone at the border is a permissible reading of "arrive" — or a way to nullify the right to seek asylum [1][4].
The Event
On June 25, 2026, the U.S. Supreme Court issued a 6-3 decision in Mullin v. Al Otro Lado (No. 25-5), authored by Justice Samuel Alito, reversing the Ninth Circuit [1][2]. The Court held that under 8 U.S.C. §§1158(a)(1) and 1225(a)(1), a noncitizen "arrives in the United States" only upon crossing the border, so a person standing in Mexico at a port of entry is not entitled to apply for asylum or to be inspected [1]. Justice Sonia Sotomayor read a dissent from the bench, joined by the other two liberal justices [3][4].
Undisputed Facts
- The vote was 6-3 along ideological lines, with Justice Alito writing for the majority and Justice Sotomayor authoring the principal dissent [1][3][9].
- The case concerns the meaning of "arrives in the United States" in 8 U.S.C. §§1158(a)(1) and 1225(a)(1) of the Immigration and Nationality Act [1][2].
- The disputed practice, "metering," involves U.S. officers at ports of entry limiting or blocking the number of asylum seekers allowed to step onto U.S. soil each day [5][15].
- Al Otro Lado, an immigration-advocacy group, and individual asylum seekers sued the government in 2017 in the Southern District of California [3][13].
- The government formally rescinded the metering policy in November 2021, after the district court ruled, and the Ninth Circuit later affirmed in relevant part that metering was unlawful [1][13].
- At its peak in August 2019, metering waitlists in Mexican border cities held roughly 26,000–27,000 names [14][15].
- The decision was one of two immigration rulings the Court issued that day; the other concerned Temporary Protected Status [4][12].
- The ruling does not by itself reinstate metering but removes the legal barrier the Ninth Circuit had erected against it [3][5].
The Pressure
Strip away the moralizing and blame. What structural realities persist regardless of which narrative wins?
- Executive control of the border
- Successive administrations seek discretion over how many people can trigger asylum processing, because uncontrolled volume at ports of entry creates backlogs and domestic political costs regardless of party [6][15].
- Judicial method as leverage
- The conservative majority's textualism and the presumption against extraterritoriality are not only legal tools but a structural lever that systematically narrows statutory immigration rights and shifts policy power to the executive [1][7].
- Geographic burden-shifting
- Whatever the legal label, blocking people at the line physically moves the human and security burden onto the Mexican side, where the costs are real and persistent [5][14].
Material realityLimited inspection capacity at ports of entry is a fixed physical constraint; when more people arrive than officers process, they wait somewhere. Metering keeps that queue on the Mexican side, where documented kidnappings, assaults, and deaths have occurred and where waitlists once neared 27,000 names [14][15]. The ruling changes who controls the queue and where it forms, not the underlying mismatch between demand for asylum and processing capacity [5][14].
Narrative as a weaponTwo narratives compete for the reader. The administration and its allied media want you to see a neutral, technical reading of one verb — "arrive" — that restores rule-of-law limits a runaway court had erased. Advocacy groups, the dissent, and sympathetic outlets want you to see a life-or-death right being switched off by where an officer chooses to stand. The primary record supports both as partly true: the statute's wording genuinely is ambiguous and was litigated for years, and the humanitarian harms of stranding people in Mexican border cities are also documented. Each side downplays the other's strongest point — the right minimizes the deaths, the left minimizes the genuine textual question.
How Each Side Sees It
Each major actor’s view — how it frames things, its underlying incentive, and how it’s materially affected. Tap a side to read it.
Frames it asThe phrase "arrives in the United States" should carry its ordinary meaning — you have not "arrived in" a country until you are physically in it — and Congress deliberately replaced the older phrase "at a land border or port of entry" with "arrives in the United States," showing intent to require actual entry [1][7]. The presumption against extraterritoriality means U.S. asylum obligations do not extend to people still standing on foreign soil; metering is a lawful way to manage limited inspection capacity at ports of entry rather than a denial of any right that has yet attached [1][7].
WhyTo restore executive control over who and how many people can trigger asylum processing at the border, reducing pull factors and backlogs while honoring the administration's enforcement agenda [6][8].
Impact on themGives the administration a durable, court-blessed tool to limit asylum claims at ports of entry and a precedent constraining lower courts from expanding statutory immigration rights [6][7].
Frames it asSince 1917 the law has required officers to inspect anyone who presents at a port of entry, and Congress wrote asylum to apply to a noncitizen "whether or not at a designated port of arrival"; allowing officers to physically stand at the line and block people lets the government evade mandatory duties and effectively repeal the right to seek protection [4][5]. Metering doesn't reduce migration — it strands vulnerable people in dangerous Mexican border cities and pushes them toward deadly illegal crossings [5][14].
WhyTo preserve a meaningful, enforceable right to request asylum at the border and to protect people fleeing persecution from being turned back into harm [5][10].
Impact on themThe decision removes their main legal shield against metering and other turn-back practices, leaving future relief to Congress or to as-applied challenges [3][12].
Frames it asTurn-backs shift the humanitarian and security burden onto Mexican border cities, where stranded migrants face kidnapping, extortion, and violence, and strain local shelters and services [5][14]. Decisions made unilaterally in Washington create cross-border consequences Mexico must absorb without a formal say [5].
WhyTo avoid becoming an indefinite waiting room for U.S.-bound asylum seekers and to manage the strain on northern border states [14].
Impact on themLikely renewed buildup of migrants in cities such as Tijuana and Ciudad Juárez if metering resumes, with associated humanitarian and law-enforcement costs [14][15].
Frames it asThe majority's reading lets the government nullify a statutory command by the physical placement of an officer's body, an absurd result Congress could not have intended; the consequence is foreseeable death and danger for people denied any chance to ask for protection [3][4]. The proper question is not metaphysical geography but whether the law's inspection duties can be switched off by where an agent chooses to stand [4].
WhyTo preserve judicial enforcement of statutory protections and to flag the human stakes for the public and Congress [4][10].
Impact on themTheir dissent has no legal force but shapes public debate and signals avenues — legislative fixes, narrower future challenges — for opponents of the ruling [4][11].
The Bias Ledger average rating 4.7

| Outlet | Vantage | Bias | How they frame it | The tell |
|---|---|---|---|---|
| The Hill | U.S. center | 2 | "Supreme Court rules asylum seekers may be turned around, siding with Trump." | Neutral verbs and attribution throughout; a separate piece foregrounds Sotomayor's "More people will die" line, which signals editorial interest in the dissent's drama [9]. |
| NPR | U.S. center-left | 3 | "The Supreme Court says the U.S. can turn away asylum seekers at the border." | Largely procedural and balanced, but the verb "turn away" and prominent placement of the dissent lean toward the humanitarian frame over the statutory one [4]. |
| Al Jazeera | Qatari state-funded | 4 | "US Supreme Court paves way for government to block asylum seekers at border." | Centers the migrant and rights-group perspective and international refugee norms; "block asylum seekers" emphasizes obstruction, and the U.S. statutory-text debate is treated as secondary [5]. |
| National Review | U.S. right | 5 | "Today's Ruling in Mullin v. Al Otro Lado" — a legal defense of Alito's textualism. | Focuses tightly on statutory text and the extraterritoriality presumption, presenting the majority view as the obvious reading while largely setting aside the dissent's consequences argument [7]. |
| Fox News | U.S. right | 6 | "Supreme Court hands Trump two major wins on asylum and immigration," with an op-ed titled "Supreme Court reins in judges who rewrote the asylum law." | Frames the outcome as a political "win" and casts the Ninth Circuit as having "rewritten" the law, treating the administration's reading as plainly correct and downplaying humanitarian stakes [6][8]. |
| Common Dreams | U.S. left / progressive | 8 | "'More People Will Die': Sotomayor Reads Searing Dissent as Supreme Court Lets Trump Block Asylum Seekers." | Headline is built from the dissent's most alarming quote; loaded words like "searing" and framing the Court as enabling Trump make the angle explicitly advocacy-driven [11]. |
