I am presently on L1 with company A and have applied for H1 through company B. I have got the H1B approval with COS effective from Oct 1st with Company B. FYI, I do not have a client to work yet with Company B. Meanwhile I have got another oppurtunity and decided to move with Company C. Company C has applied for new H1B (transfer) after 1st Oct and have the receipt number from USCIS. My Question is am I eligible to work with Company C (without working for a single with CompanyB) with this receipt? Am I considered to be H1B postability?
