Hi Ron, I am currently working for employer A on H1-B(expiring Sep'17) and i am past the 6th year of H1-B. My original I-140 was filed by employer A with priority date for Jan'14. Since then i was promoted to managerial position and have refiled the PERM as a "manager". I now have the LCA approval for the same but I-140 has not been filed as yet. I am looking to change job to company B and wanted to know if Company B can file for new I-140 immediately or will they have to refile a new LCA. Incase a new LCA has to be file, Can Company B ask for visa extension if the LCA hasnt been approved by then?
