Hello, I am applying for a visitor visa from the U.S. I got the "passport request letter" and sent my passport along with all the required stuff to the CPC in Ottawa (the option 1 on the list). My USPS tracker shows that it was delivered on 11/30, last Friday. I haven't got any emails or messages from them notifying me that they received my passport, so I am a bit worried. Am I supposed to receive such a message? How do I know the status of my passport and when it is being sent back? Thank you!
