Pijiang, Thanks a lot for your reply.
We are clear on the second and the third question, for the first question, sorry that we did NOT make it clear at the first time. Let me rephrase the question once again:
My hu*****and is going to change job (I140 approved, I 485 pending over 180 days, H1B second term), he still works in the IT field (programmer/analyst), similar job type and similiar job responsibility.
But company wise, he used to work for a Semiconductor company, the new job is offered by a Health Insurance company (non-profit). These two companies seem to belong to different industries.
Our concerns are: Whether changing job from one industry to another industry will cause any trouble for our I485 approval, although the job type/job responsibility is same (still in IT field).
Thanks a lot in advance for your answer.
