Summary

A short, plain-English overview of Mullin v. Al Otro Lado.

The Supreme Court reviewed whether an alien standing in Mexico at the U.S. border is considered to have 'arrived in the United States' under the Immigration and Nationality Act (INA) for asylum purposes. The Court determined that an alien only 'arrives' when they physically cross the border. The decision reversed the Ninth Circuit's ruling, which had affirmed that encountering a U.S. official at the border constituted arrival.
