H1 Transfer and joining date

[sheel1994]

Hi All,

I am in the following situation:

I am working for company A on a H1 visa and got a offer from Comany B. They transferred my H1, but now they want me to continue with company A for some more time. So my question is how long I can work with company A after H1 Transferred to company B?

Thanks in advance for any pointer or help.

you can work for A as long as A's approval is valid.
