Supreme Court Allows U.S. Officials to Turn Back Asylum Seekers at Mexico Border
On Thursday, the U.S. Supreme Court issued a 6‑to‑3 decision that permits federal immigration officials to deny entry to people who arrive at the U.S.–Mexico border and seek asylum. The ruling, delivered in Mullin v. Al Otro Lado, was written by Justice Samuel Alito and joined by Chief Justice John Roberts and Justices Clarence Thomas, Neil Gorsuch, and Brett Kavanaugh. The dissenting panel—Justices Sonia Sotomayor, Elena Kagan, and Ketan J. Jackson—argued that the decision would undermine the nation’s long‑standing tradition of granting refuge.
The majority held that the Immigration and Nationality Act (INA) requires a foreign national to “arrive in the United States” before an asylum claim can be filed. Interpreting the statutory language literally, the court concluded that a person who remains in Mexico does not meet the definition of “arrived.” The ruling therefore overturns a 2024 Ninth Circuit decision that had deemed the practice of turning back asylum seekers unlawful.
This decision follows a decade‑long legal battle over the Trump administration’s “metering” program, which limited the number of migrants who could be processed for asylum at the border. First implemented in 2018, the program was repeatedly challenged in federal court, and the Ninth Circuit’s 2024 ruling held that the practice violated the INA’s requirement that an asylum seeker be inspected by a federal officer before a claim could be considered.
According to The Guardian, the Supreme Court’s ruling “fundamentally reshapes the U.S. asylum system” by removing the statutory bar that had previously required a migrant to cross the border before filing a claim. The majority stressed that the phrase “arrives in the United States” carries an ordinary meaning and that the INA’s text supports that interpretation.
In her dissent, Justice Sotomayor warned that the decision would effectively deny asylum seekers the opportunity to present their cases before an immigration judge. She criticized the majority for overlooking the policy’s impact on vulnerable migrants and for eroding a core element of U.S. humanitarian practice.
The Trump administration had long maintained that the INA permits officials to deny asylum to people who have not yet entered the country. The Department of Homeland Security supported that position, arguing that the policy “helps manage the flow of migrants and protects national security.” The Court’s ruling now provides a legal basis for the administration to continue the practice.
The ruling is expected to have immediate effects on immigration courts and border operations. Immigration judges will no longer be required to hear asylum claims from individuals still in Mexico, potentially easing the federal immigration system’s caseload. However, the decision also raises concerns about migrants who are turned back without the chance to seek legal protection.
Legal scholars note that the ruling could influence future asylum policy debates. An analysis by SCOTUSblog highlighted that the decision clarifies the standard for reviewing asylum claims and may shift the balance of power toward the executive branch in determining who can seek protection.
The Supreme Court’s decision arrives amid heightened political debate over immigration. Advocacy groups such as the American Civil Liberties Union and the National Immigration Law Center have described the ruling as a setback for migrant rights, while supporters of the Trump administration praised the court for upholding the rule of law.
The Court has not yet set a schedule for implementation. The Department of Homeland Security is expected to issue guidance on how the policy will be applied at the border, and the decision may spur additional litigation as affected parties challenge its application.
In sum, the Supreme Court’s 6‑to‑3 ruling in Mullin v. Al Otro Lado allows U.S. immigration officials to deny entry to migrants who arrive at the U.S.–Mexico border and seek asylum, based on the interpretation that asylum claims can only be filed after a person has “arrived in the United States.” The decision reverses a lower court ruling and is poised to reshape asylum seekers’ experience, immigration courts’ workloads, and the broader debate over U.S. immigration policy.
