A federal appeals court said Friday that the Trump administration could temporarily continue to force migrants seeking asylum in the United States to wait in Mexico while their cases are decided.

A three-judge panel of the United States Court of Appeals for the Ninth Circuit issued a stay of a lower-court ruling four days earlier that blocked the administration’s protocol. The appeals court will consider next week whether to extend that stay — and allow the Trump administration policy to remain in effect for longer.

The administration in December announced its new policy, called the migration protection protocols, arguing that it would help stop people from using the asylum process to enter the country and remain there illegally. President Trump has long been angered by so-called catch and release policies, under which asylum seekers are temporarily allowed in the United States while they wait for their court hearings.

On Monday, Judge Richard Seeborg of the United States District Court for the Northern District of California issued an injunction against Mr. Trump’s new protocols, saying that the president did not have the power to enforce them and that they violated immigration laws.
