Mailing process unclear, sending passport to Buffalo for a TRV

[prateek_sikka]

Hello,
I want to get a multiple-entry visa and in order to do so I need to send my passport to Buffalo. I am currently in Canada. I am kind of confused in the mailing process.
 
1. I buy an Xpressspost-USA envelope and fill in my address in "From" field and Consulate's address in the "To" field.

2. Now in this envelope, I put inside the filled forms, my passport and an Xpresspost National envelope(not USA). In the xpresspost national envelope, I fill my address in the "To" field, but I don't know what to fill in the "From" field.  
Kindly reply me as soon as possible.
THANKS!!

- This means you know the Consulate's address. Use this address in the "From" field in the other envelop.

2. Now in this envelope, I put inside the filled forms, my passport and an Xpresspost National envelope(not USA). In the xpresspost national envelope, I fill my address in the "To" field, but I don't know what to fill in the "From" field.

-Use the Consulate's address or keep it blank. Usually they put a stamp (seal) in the "From" field when they will send it to you.
In addition, are you sure that Xpresspost National service is an International service by Canada post? Ask the post office which one is internationa Xpresspost and which one is domestic (within Canada) post.
Thank you.

thx for the reply.
this is wht the website says:
-Buy 24x32cm National Xpresspost (not USA)
-Complete the mailing label showing your full mailing address in both the "Deliver To" and the "Return Address" field. Make a note of the tracking number.
-Taking advantage of our proximity to the Canadian border, we can make arrangements to have your passports mailed from Canada.
