I am currently working for employer A in India and have an H1B which was stamped in Nov. Recently i got a better offer from employer B who are ready to do a premium transfer of my visa. But if i resign before my visa gets transferred from A emp A will cancel my visa and petition. So i have submitted my docs to emp. B for premium processing. Now my questions are :
Will A get 2 know that my visa is transferred ?
Can i resign from A once the petition filed by B is approved by USCIS ?
