Hello! I applied for TRV(temporary resident visa) online within Canada, so i get the letter requesting my passport to be sent to Ottawa, i sent it the week after(september 23) my status changed in my IRCC account the next couple of days, i received an email on October 8th from them asking me to confirm my mail address i replied the same day, but its been almost 2 weeks from that and i haven't heard back from them(i have sent 2 more emails but no response), I am really concerned because it's been a month since i sent my passport, any advice?
