Hello Immigration Gurus, I need a suggestion. Here is the senario. I am working as a consultant for a staffing company (say  AAA ). They filed my H1B on April and it got approved. My OPT got auto extended till the end of September because my H1B was approved. I was working with a company ( say BBB ) and my contract is up now. Currently I am looking for other position. Here are the things I need information on. My Current OPT ( 29 month extension already taken ) expries on 2 week of July. My question is  If a new company ( say CCC ) offered me a fulltime position and ready to sponser my H1B, can I file a new H1B under CCC ? Or do I have to wait till November ( after 2 pay period)  to transfer my H1B from AAA to CCC. If there are any other ways please suggest me. Thank you for your help
