I am very curious and excited about this new announcement.
My outland spouse PR application was submitted in August 2022, and I have submitted a TRV in May 11, 2023. So for my application, it meets perfectly with this new policy. I am not sure if only new applications can fit here or the ongoing applications also work.
My status right now (May 28):
PR: The PR application has eligibility completed, and shows "Activity status updated: Background verification" on May 25, 2023. I heard that the process can take months even years if it is security screening. So I really hope to be able to have a visa while waiting.
TRV: has not been reviewed.
