I am currenlty in OPT.  I am working currently as contractor at one of companies in US. My opt will expire within next 10 days.I applied for new extension  and it's in pending status. I don't think i will get new opt extension before the expiration of old opt card. In this situation, Can i continue to work while it is in pending status or do i have to quit the job?  Please advise me for the solution of this situation.
