1- you can contact ircc thr webform by filling your Last name, first name, UCI, Passport in the box, and ask them, they can answer whether
a. We look thr the system and have not found any application like yours, it might be delivered but we have not processed them yet, so, wait more.
b. We look thr the system and can confirm that we receive your application, we will inform you soon (i received this message, and then got AOR within a week or 2)
3- you should only do upfront medical when your process is less than 12 months, or you can wait until you get AOR, you can link your application to GCkey account and it will tell you how many months left to wait. For example, if it's 11months to go, then go for upfront medical, but if it's 13months, i'd wait, because medical exam result only last 12month.
4- you can send them thr Webform ircc, with your UCI, application number and all the information they might need.
