h1b transfer question (please help)

[vssundeep1986]

Hi ALL,

i am presently working with company A I have Got H1b valid till oct-2013 and i got an offer from company B and Company B applied for transfer in may 2012 and I checked the Status of my h1b transfer on oct 23 2012 and it says the case is approved and still i havent got my h1b Transfer receipt.

At present still i am working with Company A and my pay checks are getting run there.

1)Till when can i work with company A and what is the Time Frame to join company B?

2)If the Company B decides not to give job then can i still work with company A as i have not yet joined Company B?

3) Is the day on which i receive the Transfer Recipt of approval the day of My h1b Approval ?

4) if my company A has chanced its location and the new location is 5 miles away from my previous do i need to file lca ?

Thanks,

Sandy
