I got iTA on April 5th, now collecting documents (PCC, medical etc), one of my friend confused me by saying that I have to accept the invitation or it will be auto declined. But I see no button for accept, I see one button for 'decline' an done button for 'complete application', my understanding was that I do not need to do anything other than completing the application and attaching docs and I can well do that even on the 89th Day and still be good. I have been logging into the CIC, just collecting documents, did I do something wrong? is there some other process than what I understand it to be? . Again. my plan is to do nothing for now, just start the application when I have docs with me and my understanding is - i can even do that on 89th day and keep the application as it is till 89th day, without losing ITA. Plz advise urgently, thanks a lot.
