Visa Stamping in Vancouver

[ShriSwami]

Hello All,

I've Visa stamping in last week of August 2012. I've below questions.

1. What is PIMS and how do I make sure that my details are available in it?

2. As we have to do in India, is it required to submit hard copied of any documents prior to the Visa interview?

3. Is there anything else I should be cautious about?

Thanks! Responses are highly appreciated.
