Registered Migration Agents can still lodge Decision Ready application for RSMS and ENS.
The ability for RMAs to indicate an application is decision ready has been built into the new online system for RSMS (subclass 187) and ENS (subclass 186).
Decision ready applications usually receive superior processing times from DIAC compared to non-decision ready applications.
