H1B petition approved in India, currently on F-1 OPT. Can I use that petition?

[ThibaR]

My H1B petition was approved 3 years back, while I was in India with a reputed MNC and I resigned.  I did not get to the stamping part of the process. I have the petition receipt number only. In the  USCIS website, it has an 'approved' status.

I arrived to US in H4 visa, transferred over to F-1 to study, and am currently on OPT. Can I use the previous petition number to try to get a cap-exempt H1B? If yes, what details should I take note of? (such as validity of the petition etc.)

Possible, but not sure as you did not go for stamping.
