Supporting Documents for B1/B2

[Alekssssss]

Hi,
I have an appointment in 2 weeks in Toronto, Canada. I've already got all documents mentioned in Visa Application Confirmation. However, since it's my first appointment ever, can anyone please provide with some tips of having extra documents that will be benficial to take with me to the embassy. For example, I've seen that in some countries they are asking for an envelope to send passport back, but nothing is said officially about it.
Thank you for any kind of help!

For any visa interview, keep as many documents as you can. You never know what they'll ask for & you dont want to risk your visa just because you didn't carry certain documentation.
