I found out that the eligibility status changes to 'We are reviewing..' on GC key when it's completed. My PA pr tracker was updated eligibility completed on the same date my GCkey was updated to reviewing.Eligibility just updated!
Applied on 12th, sponsor PR tracker now shows "eligibility completed" on Feb 28th, and PA GCkey tracker shows eligibility is being reviewed since March 1st.
We received no emails, no SA, no "we started reviewing...". But this means sponsor was approved and they are examining PA now right?
I've been researching if eligibility completed means AIP or SA, and some people get a separate email notifying AIP or SA so I'm confused too. If your GCkey says reviewing then it looks like it's done or almost done, it will show on the pr tracker soon. Also as long as my researching is correct lol most likely PAL is sent out when both PA and Sponsor eligibility completed. It's just background check left for us just hoping it gets done soon!!
Btw, have you tried ECAS? Some ppl see their status update there as Decision made when their eligibility completed, but I never have been able to find my application there..
