Attach my chat history here with the customer service in case this could help:
me: Hello, I believe my passport has been delivered to your office on 02/17 Thursday. It was mailed to you by FedEx (Tracking number: XXXXXXXXXXXX, signed by E.RODRIGUEZ). Should I expect an acknowledgment email and a tracking number?
Pamela: Thank you for contacting the Canada Visa Application Centre, I hope you are having an excellent day!
Pamela: Please kindly wait until Canadian Visa Application Center contacts you regarding the process of your application, Canadian Visa Application Center will give you the tracking ID and tracking status, the notification can take from
8 to 10 business days after the Center received the passport and documents (the notification will be sent to your e-mail).
me: The original passport request letter says my passport needs to arrive at IRCC within 30 days from 02/04, so it should be arrived on or before 03/06. I hope there is plenty of time for you to deliver it on time for me.
Pamela:
Once that the package arrives to the CVAC the processing time to submit the passport stops counting.
