This is not so easily circumvented. If an employee on H-1B transfers to another location, the employer is required to file an amendment to the H-1B petition and go through the prevailing wage determination again. From USCIS website [1]:<p><pre><code>  You must file an amended H-1B petition if your H-1B
  employee changed or is going to change his or her place of
  employment to a worksite location outside of the 
  metropolitan statistical area (MSA) or an “area of intended 
  employment” (as defined at 20 CFR 655.715) covered by the 
  existing approved H-1B petition
