Same employer name on your pay checks?
If so, and all you did was change the physical job-assignment-location, you should be fine ... just carry recent paystubs from the employer who's name appears on the unexpired visa in your passport.

If your employer did not file a new LCA before you start to work for the new end-client and an amendment petition, the U.S. Consulate might deny your visa application.

Mr. Murray's response is NOT legal advice and does NOT create an attorney-client relationship. You should NOT rely on this response. Mr. Murray's response was generated without conducting a full inquiry as would occur during a face to face attorney-client consultation. It is likely that the response above may be made less accurate, or become entirely inaccurate, as you, i.e. the questioner, disclose additional facts that should only be discussed during a private consultation with an attorney. I strongly recommend that you consult an attorney who is licensed to practice law in your state (or, in the case of immigration law, and attorney in ANY state), whereupon all relevant facts will be discussed. All responses posted by Mr. Murray on Avvo.com are intended as general information for the education of the public, and not for any specific individual.
I agree with Gen. Whenever there are major changes to the terms and conditions of your employment, your employer should seek an amendment to their petition. If the work location is not temporary, it may affect pay, requiring filing a new LCA, and has been considered by some Consulates to be major change in employment.
It is not uncommon for a Consulate to deny your visa based on these facts.
This response is general in nature and cannot be construed as legal advice, given that not enough facts are known. Any comments offered on Avvo are of a general nature only, and are not meant to create an attorney-client relationship.
