H1B transfer

Hello Ram,

I got my H-1B approved this year from company A and now I have a job offer from company B. Company B has received the Receipt Notice from USCIS and have asked me to join ASAP. The problem is that is just the receipt notice, not the approval notice.

  1. What will happen if I join company B and company A revoke the approved H-1B.

  2. If company A has no role after company B gets receipt notice, then what will I do if in case company B’s petition gets rejected. Can I apply for STEM extension then? I have used only 10 months of OPT.

Please, can you help me with this issue? I am really grateful to redbus for helping others.
