I applied online for my study permit recently and my application has been approved. However, I realized I wrote the wrong postal code in my application form so I most likely won't be able to receive my study permit in the mail. What can I do other than waiting? I've tried calling IRCC too but they kept putting me on hold. Does anyone know if anything can actually be done? Further more, I need my study permit to apply for my visa which I need really urgently since I'm leaving Canada soon and I want to be able to re-enter. I do have the letter of approval already. Is that any good? Thanks!
