H1B amendment for new LCA, problem at Port of Entry??

Hi,

My employer filed my H1B with LCA belonging to Location A. I got my visa stamped but now my employer wants to send me to Location B. I heard from them that the new LCA is ready.

I am flying to US in a couple of weeks and I want to know whether the new LCA is enough at the PoE? or do they have to file for H1B amendment?

Location A is on the East coast and Location B is on the west coast.

This is my first visit to US.

Yes, these days it is recommended to file LCA followed w/ H-1 amendment.
