Will I be able to work for another company as soon as they file my h1b transfer?

Question

I work for companyA on my h1b. Now companyB is ready for h1b transfer and asking me to start working for companyB as soon as they file my h1b.
Will I be able to do that?

Answer 1

Well, in most cases yes, you should be able to do it

If certain conditions are met, then you can begin working for Company B once that employer's H-1B petition has been received by USCIS. Check with Company B's immigration attorney to ensure you meet the requirements for doing so.
