Finally some movement it seems, but it's dependent on the Visa office handling your file, and that can be a bit random.
I'm a FSW inland applicant with French and Canadian degrees, more than 5 years of work experience in my NOC and actually I'm even working in Canada right now. Got my AOR May 1st, Medical passed about a week after that. Background Check has been running for like 4 months now, in-between I was asked for the RCMP Criminal Record Check (which is normal given I was in Canada for the last 2 years doing my Masters), submitted that within 10 days, after that radio silence. Review of submitted documents still reads as "Provided", it's like they didn't even check what I uploaded this whole time.
I don't even know what they're looking for at this point but there's still a month left before I hit the 6 month deadline so let's see. Other colleagues of mine got their PR around the 6-month mark as well so it's just about managing the waiting game. Being a French-English bilingual doesn't speed up the process haha.
