H1B transfer denied, I94 expired, Is it possible to file extension with old employer?


My H1B transfer in premium got denied today after responding to RFE and I94 was expired on Nov 11th, 2018 (visa expired Oct 31,2018), Now is it possible to file H1B extension with old employer when visa was expired? or what are the possibilities to stay within current? Can I convert to F1?

Appreciate any quick responses.

Thank you!
