Maybe IRCC really likes you I guess . You don't think that perhaps your letter made IRCC to give your file preferential treatment? They may have thought you requested for urgent processing because that's one of the few reasons an applicant would attach a letter.I did not give any reason for needing the citizenship early at all. I only explained the application I have filed. I did not need it urgently processed either. Thanks!
Congrats on getting your file processed before others lol
