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.)
