My student visa application was rejected because I was lacking police clearance. However, I did not receive any notice that I needed additional documents. I applied using the IRCC portal. And also, on the Background check section of the application it stated that my background check was still ongoing however when I received their decision on July 16... it suddenly changed to completed on May 11. Is it possible that my IRCC portal isn't receiving messages on time? do I need to update anything on my account?
