Do they ask for something ? a secret number included in the packet 3? the packet 3 checklist or anything ?
Because i want to go asap in order to have it asap too!

and i know i need for AOS but it's valid for a year so no problem

I had a letter in my packet that I had to present for the medical. They asked for it. I would wait until you receive your packet before you book the medical. I was able to get my RCMP police check without any documentation from the Consulate, though, so you can probably get that done, along with ensuring you have your passport and your long form birth certificate.

you can do your medical as soon as you get your packet 3 from Montreal...it will have your case number...

while your waiting you can also make sure you have your vaccinations up to date, and make sure you have your LONG form birth certificate..

I'm french (from france) well... and canadian
but my certificate come from france and i have the translation etc
i have everything rdy !

I was able to book and have my medical appointment before packet 3 came to me, because the doctor I went to didn't require anything from said packet.

I had booked my appointment a month in advance (at the time, TSC was processing things in 2-3 months) because I wasn't sure how fast his schedule booked up and I wanted to make sure I had a time slot close to when I thought the I-129f would get approved. The receptionist gave me a list of things to bring, but nothing from packet 3. I was ready to call them back if it looked like I wasn't close to approval, but a week before the medical my petition was at NVC, so I took a copy of the notice (which had my Montreal case #) with me -- turns out I got packet 3 a couple of days after the medical.

Check with the doctor where you plan on having the medical -- they will tell you what you need to bring.

yep, like the above stated! All depends on the Dr!! Some want the letter stating you require the medical, some do not care!! Simple phone call solves that!!

just did, they wanted it (also added what they asked in the embassy section)
