I just keep waiting for them to do the work. As you mentioned, they do seem to start working, which is good, but still too slow.
But I have an interesting finding I would like to share from the newest IRCC notes I received. There is nothing new on the notes since the last CBSA notes I received one month ago. There is a note labeled integrity which should be exempt from the Acess of Information Act. I was only able to see that label and the time but everything else was blanked in the previous CBSA notes. But this time, I guess the staff is a bit careless so there is one line left on the notes sent to me. It says " Officer: Please review large deposits, found on xxx bank statements". I guess this might be the reason why my case was sent to RROC. RROC is initially used to process general EE cases that require international knowledge. Maybe the banking statement in the US I provided is hard for the CIO to confirm and thus they sent it to RROC so that someone there who is familiar with the US can review it. This also reminds me that there were several people from the same country who got approved on the same day. If this is true, I guess being sent to RROC is not fully random.
It would make sense that RROC is both random and not random. My application and a lot of other applications get assigned from CIO directly to RROC, while others are transferred from CIO to a Visa Office and then to RROC. Even if RROC is a specialized office for handling applications requiring international knowledge, it could be that such cases are few hence they are mandated to also process normal cases.
I got an ADR while my application was with CIO to submit a passport with 6 months validity so that could also be why my application was moved to RROC,
@Mickey55555 once suggested that if an officer has doubt about an application they send it to RROC, I would say maybe it is not really doubt maybe it is if an officer thinks an application requires extra attention. In the WhatsApp group we see a lot of people with RROC as their PVO getting PPR without a single ADR so I think it is safe to say that most applications in RROC do not have issues and I think if your gcms notes confirms eligibility is passed, all is complete on tracker and you have called IRCC and they verified security is passed you have nothing to worry.
@legalfalcon once said that a notes labelled integrity are random checks to verify the officers are doing the right thing but yours is quite specific, I think a quality assurance officer picked your file at random looked at your bank statements and asked a VO to review it further. I might be wrong. Like I said before if eligibility and security is passed I do not think you have any thing to worry about.
