H1B Extension / Transfer

Hi,

I have H1B petition which is valid from Nov 2019 to Sep 2020. I did stamping recently which is also valid till Sep 2020, but never traveled to US, and currently in India only. Now my questions are.

  1. If I didn’t travel to US till Sep 2020, and if my petition get expired by Sep 2020, my current employer apply for Extension after expiry?
  2. If I didn’t travel to US till Sep 2020, and if my petition get expired by Sep 2020. Can another employer initiate H1 Transfer after expiry?
  3. Can my current employer apply for Extension before expiry even if I didn’t travel once to US with my current stamping/ petition?

Regards
