It appears that wording is present for almost everyone whether they provided actual additional documents or not. That's what my profile said the last time I checked and I did not get an additional document request from IRCC. It went from "documents not needed" to "we are reviewing additional docs", not sure what it says now.I dont think so, this clearly says "Additional" documents which are what IRCC asks for after the application. Initially my status was "We do not require any additional documents, we will let you if this changes". Later along with Medical Passed, they requested for Additional Document (Singapore Police Clearance Certificate) and after I uploaded the same on 14 Sep, the status is now changed to "We are reviewing your additional documents", which has been the case for last 2 weeks
