LCA Address & I129 Address

[Opt2h1]

Hi - I work fulltime with a mid size American Employer and working on one of their implementation project(No EVC). In my LCA - the place where the employee intend to work is my employer's address and in I 129 - it is my Project's location where I actually work. My H1B was approved with such details.

My question is - will there be a problem related to this scenario ? My employer and their attorney says that I do not need to change my LCA to my work location as they are in same Metropolitan Area and couple of miles apart. Is it true?

Also what location should i fill in my DS -160 for taking VIsa Appoinment.

Any views and suggestions will be really appreciate.
