Court rules asylum seekers must physically cross the border before the government must inspect them or accept asylum applications
What it does
The Court held that a noncitizen "arrives in the United States" — and therefore triggers the government's duty to inspect and allow asylum applications — only when the person physically crosses the border into U.S. territory. A noncitizen who is standing in Mexico, even directly at the threshold of a port of entry, has not yet "arrived" and cannot legally compel inspection or an asylum application. This ruling reverses a Ninth Circuit decision that had found the government's "metering" policy — which limited how many people could enter each day — to be unlawful.
Who benefits
Federal border officials and the executive branch, who now have legal authority to limit the number of noncitizens physically entering the country each day without triggering mandatory inspection or asylum-processing duties under federal immigration law.
Who is affected
Noncitizens who travel to U.S. ports of entry along the southern border seeking to apply for asylum but are physically prevented from crossing into U.S. territory by border officials, and immigration advocacy organizations that represent them.
Practical impact
The government may now implement "metering" policies — limiting the number of noncitizens allowed to physically enter a port of entry each day — without violating the INA's inspection or asylum-application requirements, because those requirements are not triggered until a person crosses the border. Noncitizens who are physically blocked from entering U.S. territory at a port of entry have no statutory right under these provisions to demand inspection or to file an asylum application while they remain in Mexico. The Ninth Circuit's class-wide declaratory judgment that had barred the government from using metering within that circuit is reversed, clearing the way for the government to resume the practice if it chooses.
Majority — Alito
Joined by: Roberts, Thomas, Gorsuch, Kavanaugh, Barrett
The majority held that the ordinary meaning of "arrives in the United States" requires a person to physically enter U.S. territory — just as a running back does not "arrive in" the end zone when tackled at the one-yard line, a noncitizen does not "arrive in" the United States while still standing in Mexico. The Court found that other parts of the Immigration and Nationality Act (INA) separately refer to both actual entry and attempted entry, and the absence of "attempted entry" language in the two key provisions signals that Congress deliberately chose not to cover people who try but fail to cross. The Court also noted that Congress previously used the phrase "at a land border or port of entry" in an earlier version of the asylum statute, and its 1996 decision to replace that phrase with "arrives in the United States" suggests the newer language requires physical presence inside the country. Even if some redundancy results from this reading — since anyone who "arrives in" the U.S. is also "physically present" there — the Court said it would rather accept some overlap than adopt an interpretation that contradicts the ordinary meaning of words. Finally, the Court applied the presumption against extraterritoriality — a legal rule that U.S. laws are assumed not to apply outside U.S. borders unless Congress clearly says so — to further support reading the statute as covering only conduct on the U.S. side of the border.
Dissent reasoning
The principal dissent, written by Justice Sotomayor, argued that the majority's interpretation fixates on a single word — "in" — while ignoring the broader statutory context, history, and longstanding executive branch practice. The dissent contended that the phrase "arrives in the United States" naturally covers noncitizens who are in the process of arriving, such as those who walk up to a port of entry and present themselves to a border official, because that is the moment when they can actually seek admission. The dissent pointed out that the majority's reading renders the "arrives in" clause entirely superfluous, since anyone who has physically crossed the border is already "physically present in the United States" — a category the statute covers separately — making the "arrives in" clause do no independent work. The dissent also argued that the majority's rule creates a perverse incentive: noncitizens who cross the border illegally can apply for asylum, while those who follow the law and wait at a port of entry can be turned away indefinitely with no recourse. Finally, the dissent reviewed the legislative history of both the inspection mandate and the asylum statute, concluding that Congress has required inspection of noncitizens arriving at ports since 1917 and that the 1996 amendments were not intended to strip protections from those who had not yet stepped across the border. Justice Jackson filed a separate dissent arguing the case should not have been decided at all, because the metering policy was rescinded years ago and the Court was effectively issuing an advisory opinion on a retired policy without a concrete factual record.
Constitutional question
Do federal immigration statutes require the government to inspect noncitizens and allow them to apply for asylum when they are standing in Mexico at the border but have not yet crossed into the United States?
