Yes, my new job is related to my NIW field. But people keep talking that once change job, in my case, I'm in Parole status, that means I have to use EAD with new employer, and I couldn't swith to H-1 non-immgrant status. The H-1 new company applied for me is useless. I did lots of research, but INS just mentioned in its 2000 memo that it's legal to keep/extend H-1 with the same employer if you use AP enters, but didn't provide the clear address on the job change issue. I'm so unsure.
--> Again, you can extend/use your H1B even if you enter on AP. Also, the consensus says that even if you use EAD, you can still apply to transfer/extend your H1 status. But as I said, to avoid any problems, use H1 to enter US and don't use EAD. If you need to switch jobs, ask your new employer to initiate "transfer" of your H1 status. Tell them that you really need to be in H1 as NIW petitions are so subjective. It is not a straight forward case like labor cert based 140.
The worse secenario, if I have to use EAD (by NIW) for working at new company, can I cocurrently apply for Labor Certificate GC for my backup? I am not sure how this dual intent works? Thanks for any info.
--> Your new company or any company can initiate labor cert for you while your NIW is pending. Again, if you let your H1 status lapse, if NIW gets denied, you will be without any status until you file 485 (or get any other status). Depending on NIW with no backup status if not recommended. Have you already filed 485?
