Hi

I am currently in US on L1 , but I am also having a H1 B petition which was approved in sep 2006.

I have never used my H1B,but now I am planning to shift to H1 status at the same time I am planning to change my employer, I only have the EAD no and no documents apart from that
Is it possible to change my employer and change my status from L1 to H1.

H-1 visa if not fill the quota in certain amount of time, the visa will be revoked. I don't think your H-1 is still valid... contact your attorney.
