H1B amendment Question

My employer gave me new LCA & LCA utilization prior to relocation to client B location B from client A location A and he informed that an amendment is not needed since its just a client/location change not actual change in responsibilities.
Is this Okay or would I need to ask my employer to file an amendment for me.

I think you need to get your petition ammended…by reporting the location change to USCIS.
Just getting a mere LCA from dept of labor, how will USCIS know of the change ?

Talk to your company immigration lawyer, as HR might not know such details.
