Asking on behalf of a friend
My friend works in company A whose H1B is gonna max out in couple of months but he got a i140 filed from company B. Now after the i140 approval can company A apply for H1B extension using the i140 raised by company
Also if he has to travel back to India after the H1B max out date and if wants to come back to USA after 2 years with a different employer other than company B who filed his i140,it should be fine right.
Note: He never switched to company B who filed his i140 and so didn’t work for them for 180 days.
