I was working with employer A, H1B valid till Dec 2017. Employer B filed H1B transfer petition on 04/18/2017 and received receipt notice after a week. employer C filed H1B transfer petition on 05/03/2017. i left employer A on 05/05 and joined employer B on 05/08. I received receipt notice from employer C on 05/12. So can i leave employer B in one month and join employer C?
