Going to Canada, I94 questions.

[shankar]

My parents came from india to visit USA on B2 Multiple entry visa for 10 Years. Their currently authorized stay on I-94 is valid for 6 months, expiring in Nov.

I would like to take them to Canada for visiting and have already received Canadian visiting visa.

I have few questions.

1. Do they need to surrender their I-94 when they leave for Canada?

2. Do they get new I-94 with new date stamped?

3. What are the possiblites for getting the new I-94 for another six months of stay by going to Canada and coming back the US?

Please advice immediately

Thanks.
