Yes, I am also at least preferring to go with LCA posting, but my company's HR team is saying that it's not needed as I moved within the same MSA.
Byt my worries is if an audit happens, it would happen on my old address which is mentioned on both LCA and my H-1B petition. In that case, how DHS folks would come to know that I actually moved to a new address.
Though I have already filled AR-11 (address change) form for me and my dependents, but that information is only shared with USCIS, not flows to DHS.
