H1B Transfer timelines after coming to US

Hi All, @Kalpesh_Dalwadi

I have 2 questions on the H1 stamping & transfer

  1. If the Employer A who had filed petition is not sharing the copy of it (for transfer to Employer B), is there an alternate option to get this information?

  2. Assuming that a person travels to US for same employer A who had filed the petition, how soon we can initiate transfer of H1 visa to Employer B after arriving in US?

Thank you.

You can file FOIA request with USCIS and get a copy of your petition.

There is no rule around this, you may initiate the transfer very next day.
