I am transferring H1 to employer B from A on a permanent hire. I have approved I-140 with employer A for more that 5 years.
Should I ask new employer B to initiate PERM and apply I-140 again?
Is it a must if new Position name and job descriptions are different compared to what was approved in previous I-140?
Will there be any issue in future if employer B says that they will help in adjustment of status instead of filing new PERM and I-140?
