H1b-TRANSFER-IMPACT-ON-PREVIOUS-INTERVIEW

My H1B visa is refused under 221G and is under review by USCIS. And now, if I go for H1 Transfer with new employer, please clear me the below points.

  1. My old employer will be informed or must needed to be informed?
  2. Will my initial processing/consideration is still under review or it will be cancelled? i.e. after h1 Transfer, do I possess the 2 opportunities for my stamping (i.e 1st from old employer and 2nd from New Employer) or Only 1 i.e by latest employer?
    Please revert.
