Nevada,
Thank you very much for your reply and for all the reliable information.
I wish everything goes fine.

In case, (God forbid, if lay off happens),
I need to find a new job(in same/similar) category, I believe I will. However, while transferring h1b to new employer for new job, USICS may notice about it and if they issue RFE for
EVL(employment verification letter), what should be the better approach as that time I would not have EVL from petitioner employer.
I think in that case I have to submit EVL from new employer and termination letter from petitioner employer.
Just my understanding!!
