Can I get my H1B transferred before Oct 1st?

[nineballs]

I am on a H4 Visa and got approved of H1 visa from 'A' in May 2012. The h1 visa is valid from Oct 1st 2012 to Sep 30th 2015. I am interested in joining another employer 'B'.

1. Can I get my H1B transferred to 'B' before it starts on Oct 1st?

2. If 'B' goes for regular processing, Can I start working for 'B' based on H1B receipt on oct 1st?

3. While the transfer is going on, If 'A' withdraws my original petition, will I be legal to work for 'B' till the time, approval for 'B' arrives?

Thanks..

1. Can I get my H1B transferred to 'B' before it starts on Oct 1st?

=> Yes.

2. If 'B' goes for regular processing, Can I start working for 'B' based on H1B receipt on oct 1st?

=> No. Because your case of COS (fresh H1b), you need to wait till approval.

3. While the transfer is going on, If 'A' withdraws my original petition, will I be legal to work for 'B' till the time, approval for 'B' arrives?

=> You can start working with B only after approval.

1. B can file a H1 petition for you based on the fact that you have been cap counted. Nothing gets transferred.

2. No.\

3. You cannot work for B without approval with COS. You can start work with A and then if B files your H1 petition you can leave A and join on receipt.

Why did B not file if you were interested in the first instance?
