Thanks a lot for sharing the details. It helps in understanding the overall process and congrats!!!I agree it was confusing and both letters were issued within 4 days and was supposed to complete in 30 days. Both letter also had a note that this is to finalize PR application.
I had contacted CIC and wrote them a letter to confirm if have to go through both processes, no response on emails. CIC call center was also not sure but one of the agent suggested to inform LVO that we are opting out for Inland interview. Agent also told us that IRCC is trying out this New Inland process and officer must have missed interview letter and have issued PPR request.
Then COVID happened and interview got cancelled 3 days prior to interview date. Month letter got a call from Inland office that they are issuing PR. I was quite surprised and asked what else we have to do .. She said nothing else is required from PR point of view. All we have to do is start applying for SIN/Health and send them 2 Photos and they will send us PR Card.
