MohanB, The lawyer must provide you the receipt number. Just don't fight with them now, losing your temper. I know how you might be feeling in this situation. Ask the lawyer nicely first. If nothing works, then report USCIS. Once it's approved, find some ways to get a "copy" of H1B. Tell him that you need a copy because you have to renew driving license or something.. Consult with an experienced lawyer, who can transfer your H1B to another company. There must be some ways to transfer H1B without joinning that company. Legally they can, but the USCIS may ask you for paystubs.. stuffs like that to transfer.
