All, Late December Consulate requested us to redo our medicals, update our DS-260, mail our passports and new photos which we did immediately. Using their courier service (Canada post express) we mailed our passport, it was suppose to be delivered on Jan. 3rd and Canada post tacker last update shows package arrived at Montreal on Dec 30th but does not show it was delivered. As of last week, we have been following up with Canada post to see what is the actual status is, first they said they'll look into it and opened a ticket for us, when, we called back the next day to follow-up, we were told since we are not the Sender and this is actually a return label, they are not providing information to us and they closed the ticket . Although these are our passports, we have the receipt of online payment and sender address is our home address, they still consider consulate as the Sender. They said to ask Consulate to follow up with them!!!! Just wondering if anyone heard of a situation like this. One nightmare after the other.
