Actually I had taken this deferment decision almost two weeks ago and had also sent an email to the University on August 17, 2022. But till now, I haven't received any replies from them. Actually my plan is to raise a webform latest by September 1, 2022 to inform IRCC about my deferral to Winter 2023. Let me tell you something. I had spoken to the International Center at my University about this deferment long back and they gave me two email ids : one was of some recruiter and one generic email id of the international admissions department. They told me to speak to any one of these or both. So what I did was on August 17, I had sent the deferment final decision email to the recruiter, but I haven't received any replies. I am planning to send the same email once again tomorrow, but this time to the international admissions department. At least once I get a confirmation email from them, I can quickly raise a webform and attach this email reply in that. What would you suggest?
By the way, I have already dropped the courses I had registered for previously and registered for new fresh courses for Winter 23.
I would definitely contact the International Admissions Department of your respective Faculty (Arts, Science, Medicine, Law, Engineering) as it is usually they who can provide you with an official email answer with regards to your deferral. Yes, it is necessary to drop all the courses for September 2022 as early as possible and register for the new once in Winter 2023 as early as possible as well. I have done the same thing.
