Guys need your suggestion here. Please advise.

My employer (dhoti) is not willing to give me my H1B doc not even the copy of it. I missed some good job opportunities as my employers expectation did not meet the billing rate. However, it was a good rate but you know they are really greedy and wanted more...They are not really supportive and i am sick and tired of them and i really would like to change my employer if possible. But unfortunately i donot have H1B doc on hand.

Is there a WAY OUT and get rid of this employer. btw i do not have pay stub from them?

I would extremenly appreciate your coments and suggestions. THanks
