Road travel to Toronto, ON- I94

[toobrown]

Greetings

I am traveling to Toronto, ON via Buffalo, NY and will be returning to US, in 4 days. Do I need to surrender my I-94 card while exiting US?

I have been told that, am able to keep my I-94 card.

Any inputs?

Thanks

As far as i know about this then you can keep your card with you .It is a varification of a foreigner which must be with you.
