Hi, I am new to this forum and went through some of the threads trying to find an answer. But I am still not clear so posting a new thread. My I-140 is approved and it have been more than 180 days. My spouse is employed on H4 ead based on my I140 approval. I understand that if I change my job now, and if the current employer does not withdraw my I140, I can port the PD while my new employer files I-140(obviously after perm). My question is, once I change my job if employer withdraws the I-140, will it still be active? Can my spouse still continue being employed with H4 EAD? To renew the H4 ead, should we have the new I-140 approved by then or can we do by the existing I-140 approval(considered withdrawn) and H1/H4 visa extension? Thanks.
