If you got linked and created the application #, I don't think the AOR is mandatory. Good for you!I linked on august 13 and medical passed on august 20 but no AOR so far. I am glad I linked because there was PCC request letter and if I had waited for AOR I wouldn’t have seen it. The deadline to upload PCC was yesterday September 13.
Although I feel a little nervous too, making me feel unsafe about my application. Most people get AOR or emails after linking, but I guess we just have to hope for the best.
