(CNN) — The labor union representing U.S. asylum and refugee officers has asked a federal appeals court to reverse a policy that limits the ability of Central American migrants to claim asylum in the U.S.
The National Citizenship and Immigration Services Council 119 filed the brief on Tuesday.
It calls the policy a “newly created basis for denying asylum is fundamentally contrary to our immigration laws.”
The union, which has publicly split with the administration over other asylum policies, represents over 13,500 USCIS employees, including hundreds of asylum and refugee officers.
In July, the departments of Justice and Homeland Security issued a rule that blocks the pathway to asylum for most people who cross into the U.S. through the southern border without first having applied for and been denied asylum in a transit country.
