H1b transfer query

[rogerhill]

Hi,

I am in the process of transferring my H1B from company A to company B.
Could you please let me know when I can give a notice to company A - current employer?
Can I give the notice as soon as company B receives the initial receipt or would I have to wait until company B receives the H1b notice?

Thanks.

Can I give the notice as soon as company B receives the initial receipt .

This is the earliest notice you can give to A.
