I called an operator up yesterday to see if our case has been shipped to the US Consulate in Montreal. According to John, it had been sent on March 28th, the day I called. When I called the AVR this morning, it confirmed: "NVC has completed the processing of this application and has forwarded it to the embassy or consulate in Montreal on March 28th, 2011. Please contact the embassy or consulate for further questions."
Now, a couple of months ago, I found this thread with instructions on how you can track your case from NVC to the US Embassy or Consulate. You go to DHL.com and select 'Track by Reference' under the Track option. You then put in "EXP 28 MAR 2011A" as the reference number (changing the dates according to your case). Hit 'Track', and a bunch of shipments should appear, going to numerous countries. Now the thread I found said to use the day before the case was sent out as the reference number, but the day before for our case was a Sunday. I tried using Friday's date, but there were no cases sent to Canada. But when I used Monday's date, there was a shipment heading to Montreal, Canada.
If for whatever reason you want to track my case along with me, just use tracking number: 8768131783 and put it in the box here. I'm not 100% positive of course that my case is included in that shipment, but I'd say it's a very good chance. I also have signed up for email notifications on the shipment, but I'm crazy, so :D
I think I'll call up DOS a day after I see the shipment has been delivered to see if my case was received by Montreal, just to be sure.
