Wilman Rosario was the guy who sued USCIS since they were not deciding EAD applications in reasonable time, he won the case, hence the rule came into effect to decide all 1st time EAD applications within 30 days and new EAD applicants are called "Rosario Class Members"
In Rosario class , asylum applicants with initial (1st Time) applications for employment authorization documents (EADs) are to be adjudicated (decided) within the 30-day period by USCIS. By default nearly everyone falls into Rosario Class
But On June 22, 2020, the government (Trump Administration) published a new rule eliminating (removing) the 30-day processing deadline for initial asylum EAD applications.
However, a different federal court (in the the state of Maryland) held that this new rule could not be applied to members of Casa de Maryland (CASA) and Asylum Seekers Advocacy Project (ASAP). Casa de Maryland Inc. et. al. v. Chad Wolf et. al., No. 8:20-cv-02118-PX (D.D.C. Sept. 11, 2020).
Therefore, members of ASAP and CASA who file initial asylum EAD applications remain Rosario class members entitled to adjudication with 30 days.
