Supreme Court Asylum Decision: What Mullin v. Al Otro Lado Means

On June 25, 2026, the U.S. Supreme Court issued a major immigration decision in Mullin v. Al Otro Lado, ruling in favor of the Trump administration in a case involving asylum seekers who attempted to seek protection at land ports of entry along the U.S.-Mexico border.

According to the Supreme Court’s official recent decisions listing, the Court held that a person “arrives in the United States” only when crossing the border into the United States, and that the Immigration and Nationality Act does not entitle someone standing in Mexico at the border to apply for asylum or require inspection by an immigration officer. See the Supreme Court’s official recent decisions page for Mullin v. Al Otro Lado.

For asylum seekers, families, advocates, and immigration attorneys, this decision is significant because it addresses access to the asylum process at the border.

What Was the Issue in the Case?

The case involved a policy that allowed border officials to turn away asylum seekers arriving by land at ports of entry along the U.S.-Mexico border. The practice has sometimes been discussed in the context of “metering” or limiting access at ports of entry.

Asylum seekers argued that they should be able to seek protection when they presented themselves at a port of entry. The government argued that the legal right to apply was not triggered for individuals who had not crossed into the United States.

The Supreme Court sided with the government.

What Did the Supreme Court Decide?

In Mullin v. Al Otro Lado, the Court ruled 6-3 in favor of the administration. The decision endorses a policy that permitted border officials to turn away asylum seekers arriving by land at ports of entry along the U.S.-Mexico border.

The Court’s reasoning focuses on when a person is considered to have arrived in the United States for purposes of the asylum statute.

This matters because many asylum seekers try to follow legal procedures by presenting themselves at a port of entry. The decision may make it harder for people outside the United States, but physically near the border, to claim a statutory right to be processed for asylum.

Does This End Asylum?

No.

The decision does not eliminate asylum as a form of protection. Asylum law still exists. People who are physically present in the United States or who otherwise meet the legal requirements may still be able to apply for asylum.

Asylum is governed by federal law, including 8 U.S.C. § 1158. But the Supreme Court’s decision may affect how and when some people can access the asylum process at land ports of entry.

The decision is especially important for people trying to seek protection from outside the United States at the U.S.-Mexico border.

Why This Decision Matters

For people fleeing danger, access to the asylum process can be life-changing. The Supreme Court’s decision may make the process more difficult for certain asylum seekers who are attempting to present at land ports of entry from Mexico.

The ruling may also affect future litigation over border processing, asylum access, and the scope of government authority at ports of entry.

For immigrants already in the United States, the decision does not necessarily change every asylum case. But it is still an important reminder that asylum law is highly fact-specific and can change quickly based on court decisions, agency policy, and border procedures.

What Should Asylum Seekers Do?

If you or a loved one is considering asylum, do not rely on social media summaries or rumors about what the decision means.

Important questions may include:

• Are you physically present in the United States?

• Have you already filed for asylum?

• Are you in immigration court?

• Did you enter through a port of entry or between ports?

• Are there one-year filing deadline issues?

• Do you have a credible fear or reasonable fear claim?

• Are you subject to any prior removal order?

• Are there other immigration options available?

The answers to these questions can change the legal analysis.

The Bottom Line

The Supreme Court’s decision in Mullin v. Al Otro Lado is a major development in asylum law and border processing. It does not end asylum, but it may limit access to the asylum process for people who are outside the United States and attempting to seek protection at land ports of entry.

Anyone affected by asylum policy should get individualized legal advice before making decisions about filing, travel, border presentation, or immigration court strategy.
