Canadian student lost I-797 - does it matter?

Question

I'm going to be studying in the US in the fall and about a month ago I paid the SEVIS pee and printed off a copy of the receipt. The I-797 arrived the day I was leaving, but in the rush of packing, I forgot to take it. I have all the rest of my paperwork (I-20, etc). I'm getting conflicting information from online sources -- some say that as a Canadian student, the I-797 is only proof of payment of the SEVIS fee, and that the official online receipt is fine too. I'm having a hard time getting in touch with the DHS, so I was wondering if anybody out there has an info they can share.

Answer 1

Perhaps you can ask someone at home to mail it to you?  

Answer 2

Ask if you could just request for another copy of the receipt.
