I've completed 6 years in USA (H1-B) in 2016 and my i-140 was approved last year and i got my new extension for another 3 years until 2019 under I-140. But due to family commitments I got a job in India and I came back. I left my job in USA 10 days ago. Is it still possible to go back to USA with the H1B of my old employer. If I find a new employer, should they transfer it or does it still hold good? or they can still use my i-140 to get the H1-B extension? Please advise me on what is the process to get back to USA with my stamped visa until 2019?
