H1B Transfer question

[Navan]

Hi,
Please help with my questions

Currently I am working with company A
I have applied for H1B transfer through company B.
Is it necessary that I should join Company B ?

Can I continue working for company A ?

Can I apply for transfer through company C sometime later.

Thanks
Nava

Is it necessary that I should join Company B ? No, it's not

Can I continue working for company A ? - Yes, but make sure that both companies know that you have H1 petition. What if one company revoked your petition to USCIS then you won't be able to work for that company into future if you'll decide your mind again.

Can I apply for transfer through company C sometime later- YES, you can transfter as many company as you want. But all the time its the same process, documents and fees (190 + 1500 (or 750, depends on employee size)+ 500 and lawyer fees).
