H1B stamping at Toronto

Registered Users (C)
The date on my H1B stamping in the passport and I-94(WHITE CARD RECEIVED AT THE TIME OF ENTRY INTO US)had expired on July 2000. I was never out of status and my I-797 has time till December 2003. I have an appointment at Toronto on March 21st for H1B stamping on my passport. If the VISA is denied,Can I come back to US based on the date in I-797 form? Did any one have experience of travelling on the Greyhound bus to Canada?
Any information is highly appreciated.
Thanks-SSV
