Hi,
My wife and children are in Canada and they got PR last month. With the eligibility letter, they asked me as an outside dependent to send my application to Cairo VO. I mailed it to the office but they refused to receive the application because there are a submission fee (small amount) that I did not realize. I resent it to a friend in Cairo who picked it up, paid the fees at the VO, submitted the application and got an acknowledgment receipt with a tracking number. The tracking number shows the file has been forwarded to IRCC.
