H1-B transfer

USA H1B Visa
1

Hi,

I am on H1-B visa and working for Company-A.

I want to join a new employer Company-B.

The immigration team in Company-B says that as soon as they file the H1-B petition (Form I-129), I can start working for the new employer (Company-B).

Is it true? Is there any problem in this approach?

Thanks in advance

P.S.: I am from India

They have emailed me the FedEx shipping delivery to USCIS (not the receipt I-797C)

Thats almost correct but here is the correction.

They said: as soon as they file the H1-B petition (Form I-129), I can start working for the new employer (Company-B).

The correction is : as soon as they file the H1-B petition (Form I-129) AND ITS RECEIPT IS RECEIVED, I can start working for the new employer (Company-B).

Are you sure? The immigration specialist in the Company-B says: “Its legal to start working for Company-B once the H1-B petition reaches USCIS”. They ask me to give my notice to my Company-A, where I will serve 2 weeks.

Please let me know your thoughts.

Thank you
