H1B transfer to new employer without the Visa

Hi Saurabh,

I got my H1B approved last week and i haven’t done the stamping yet. I have few questions

  1. Is it possible for me to change the employer before going to Visa Stamping. As im getting good oppurtunities .

  2. If my visa gets denied or i get 221g is it possible for me to use H1B approval and go to visa stamping with new employer…?

I applied H1B from India itself.
