请教小白兔,mytwocents, radiology等各位好心人，NIW 485Pending 180

My case：NIW, 485pending 180天以上，same or similar job and title, moving from a university to a pharmaceutical company located in a different state

Question:

Since the address is totally changed, do I have to report to USCIS for changing of employment although I was told I would not be required to do so? If yes, what kind of document I need or the new company should prepare?

Thanks a lot in advance!
