Am aint sure about it, however I have been checking up some posts on this forum and the majority have got the so called golden mail when they reached out their 22M. I do hope am wrong thu. My application was received in Feb 2019 followed by the AOR in April and I was expecting the process to be much faster or something, as my agent was saying its about 15-17 months to get the PR.Its still the average processing time, some can bet their PPRs earlier. It all depends on the profile!
I wish you all the best.
