  "factual_background": "In Fiscal Year 2016, U.S. Customs and Border Protection (CBP) faced a roughly 70% surge over Fiscal Year 2014 in noncitizens seeking admission at southern-border ports of entry (more than 150,000 arrivals). Multiple ports — Brownsville, Hidalgo, El Paso, San Luis, San Ysidro — reported overcapacity, with the San Diego Field Office reaching 155% and the Tucson Field Office reaching 231% of detention capacity. In November 2016, during the Obama Administration, DHS adopted a practice known as 'metering' (also called 'turnback'): CBP officers would stand on the U.S. side of the border and prevent noncitizens without valid travel documents from crossing into the United States, generally directing them to return later. In 2018, the first Trump Administration formalized the policy through an Executive Assistant Commissioner memorandum and a Secretary of Homeland Security memorandum authorizing CBP to 'establish and operate physical access controls at the borderline.' In November 2021, the Biden Administration rescinded those memoranda. The current Administration has not adopted a new metering policy but represents that it 'considers metering a critical tool for addressing border surges' and 'seeks to retain the option of reviving the practice.' Resp. Br. 18-19 (characterizing this as a request for an advisory opinion on a vacated policy); Pet. Br. 7 (defending the position).",

      "summary": "The phrase 'arrives in the United States' has an ordinary-English meaning: a person arrives in a country only when she comes within its borders. A person stopped in Mexico has not 'arrived in' the United States. The Ninth Circuit's interpretation effectively replaced the statutory text ('arrives in the United States') with alternative text of its own ('presents herself to an official at the border, whichever side of the border she is standing on'). Section 1158(a)(1)'s context confirms the reading: § 1157 governs admission of refugees from 'foreign countries,' while § 1158 governs asylum for aliens 'currently in the United States' (quoting INS v. Cardoza-Fonseca, 480 U.S. 421, 433 (1987)). The respondent's reading conflates the two regimes. Section 1225(a)(1)'s context leads to the same result: it requires inspection, interview, and (where applicable) detention and removal — actions that immigration officers in the United States cannot perform on aliens in Mexico. Verb-tense arguments (present tense, present progressive) do not bear the weight respondent puts on them: any redundancy between 'physically present in' and 'arrives in' is the kind of 'belt-and-suspenders' drafting that Congress commonly employs (Barton v. Barr, 590 U.S. 222, 239 (2020)).",

(a) Verb tense: Congress's choice of the present tense 'arrives' (rather than past tense 'arrived') — and the use of present-progressive 'arriving' in nearby provisions and in the implementing regulation defining 'arriving alien' — indicates coverage of those in the act of arriving, not only those who have completed arrival. (b) Surplusage canon: petitioner's reading collapses 'arrives in the United States' into 'physically present in the United States,' depriving the former phrase of independent meaning. (c) Self-defeating mandates: Sections 1158 and 1225 are written as mandatory commands ('shall be inspected'); reading them to permit officers to evade those mandates by physically blocking applicants is a self-defeating construction.

To 'arrive' means 'to reach a destination.' For someone coming to the U.S. to seek asylum, the relevant destination is the U.S. border, where a border official can be addressed. The parenthetical 'whether or not at a designated port of arrival and including an alien who is brought to the United States after having been interdicted in international or United States waters' confirms that Congress contemplated arrivals at non-port locations. The 'physically present in' phrase covers aliens within U.S. borders; the 'arrives in' phrase covers aliens 'who encounter officials at the border, whichever side of the border they are standing on.' Sale is distinguishable: it concerned aliens on the high seas, not at a port of entry. The presumption against extraterritoriality does not apply: the conduct being regulated is that of U.S. immigration officers, who act on U.S. soil.",
    "panel_dissent_r_nelson": "Panel dissent (R. Nelson, J., later joined by 13 additional Ninth Circuit judges in opinions or statements during the en banc denial process): Congress's redundancy is acceptable — 'belt-and-suspenders' drafting is common (Barton v. Barr). The entry-fiction doctrine explains why Congress used both phrases: aliens at U.S. ports of entry are on U.S. soil but are deemed not to have 'entered'; the 'physically present' phrase ensures coverage of those between ports, and the 'arrives in' phrase ensures coverage of those at ports notwithstanding the entry fiction. The ordinary meaning of 'arrives in [a place]' requires being within that place. Corpus-linguistics evidence (cited by the dissent though not argued by any party) confirms that 'arrives in' is not satisfied by reaching the place's boundary without entering."

Petitioner argues the focus is on the alien's location (Mexico); respondent argues the focus is on the conduct of U.S. officials at the border (U.S. soil).

Corkran responded that the § 1157 program is entirely elective (the President chooses whether to admit refugees), is not something individual refugees can apply for, and does not implement Article 33 non-refoulement obligations — those are implemented through § 1158 and § 1225 asylum processing.

Whether Sale's reasoning extends to a land-border port-of-entry context where U.S. officials physically interpose themselves is the central jurisprudential question, and the argument did not produce a clear resolution from any side."
