hi! Congratulations to you as well.
i logged in to my CIC account and there is an option there to link your application. I tried searching my application using my UCI and Personal Information. As per the date I became PR I used the date on the letter I received. First try, I didnt found the application so I tried again the next day using the same details and found and linked the application in my CIC Account. I believe the Landing Office filed the application as its our new and first Pr card (i linked my pr card app when my documents (photo and letter) is out for delivery). Until now there is no update and its still in "Submitted" status (which is understandable given the current processing time is 113 days).
I am PNP Inland (Alberta) but I am currently in Ontario. I can't moved yet because Im afraid to travel because of the virus. So I applied my SIN Online here in Toronto since I have a Proof of Address here. I uploaded the letter, passport and bank statement as my documents. Filed last June 2 and still waiting for the mail to come.
I hope I helped. Im no expert and I only get ideas on what to do in this forum.
congrats and good luck!
