How to use previous Approved H1B(OCT'2007)

USA H1B Visa
1

I had an approved H1B on 2007. Is it possible we can utilize it somehow? The status is still showing in approved state. I don’t have any document with me. If my employer wants to use it, how they can proceed based on Receipt number.

You have 1 more year to work. 6 years from FY year it was approved for.
