I am the principal applicant, and submitted the application package in May 2nd. It's going to be 8 weeks on two days. No news on my end. How long has been taking to receive the letter of acknowledgement this year? Can I call someone to have more information about this? I try to call the IRCC call center but it's impossible to get someone on the phone. The automated system requires a case number to access my file, which I don't have yet. Any advice?
