The Supreme Court agreed to review the policy of Donald Trump's first administration in a case that will determine when a person who "arrives" in the United States and requests asylum can enter the country.

Federal law requires the government to process asylum seekers who arrive at ports of entry, but during his first term, President Donald Trump implemented a policy that accepted immigrants' requests but prevented them from entering the United States until they had a court date in immigration court. Most of these people had to wait in Mexico under the policy known as "Remain in Mexico," which faced several legal challenges and was suspended during Joe Biden's administration. The Al Otro Lado, one of the most prominent in defending asylum organization seekers, led the cases of several immigrants in California in a legal battle that reached the appeals court in San Francisco, where the ruling was in favor of the migrants, prompting the Trump administration to appeal to the Supreme Court last July.
