Mine was sent July 27th too and received by July 31st.. Then Sept.28 we called the IRCC to ask what was the status of my app cuz it's been 2months. So we found out that they sent our package back and I received it on Oct.7 then resubmitted yesterday Oct.8Hi everyone, I sent in my application on the 27th of July but did not receive acknowledgement of receipt till the 3rd of September. Has this happened to anyone else, or does anyone know why this happens?
