I have read some applicants got the golden email without seeing any updated on the profile throughout the process. Others got medicals passed, documents provided and BG IP in one update.
From what I have seen on this forum, each case is different. For example, if you are PNP, you have to provide schedule 4. Some applicants know this in advance, so they upload schedule 4 along with the LOE, others don't. For those who do, they would probably not get any updates for long time, those who didn't uplaod will get request for additional docs in which they see the progress. IMO all dec AOR applicants have provided all docs required either in advance or through the request for additinal docs. What I am trying to say, is that at this point in time, we would probably not see any progress on Dec AOR untill PPR start coming...
