H1B approved in 2008 but unused

[raka_stanford]

Hi,

Here is my slightly off-beat case.

- I did my First MS in 2006. Applied for OPT. Did not use it. Went back to India.

- In 2008, a company applied for my H1B. It got approved.

- But the company went bust. They shut down. I never used the H1B.

- I can not contact them to get the EHC# or receipt or other details.

Now

- I am doing my Second MS on an F1 visa.

- I will be done in December, and can find a job in a reputed company easily.

Questions.

--------------

1) I did not use my OPT (I applied and got the card). Can I re-apply?

2) If OPT is not possible, can I apply for H1 now, without the cap, because I was approved once?

3) Will I need my old EHC#? If so, Is there a way to find out the receipt number from 2008 via USCIS (I can not contact anyone in the company) ?

4) {Relevant only if H1 or OPT is not doable} Is it advisible to enroll for a thrid MS in a not so reputable college, and start CPT until the quota opens again? How hard is it to enroll in a new school while I am here?

I deeply appreciate your time and advice.

Thanks

Rakesh
