LCA wages changed from Level 4 wages to Level 3


I am working for a service based company as a Computer Analyst under Wage 4 category and apparently I got transfered to a new location and the new LCA has procured under Wage 3 category and reduced my annual income. Can you please let me know if this is a legal thing to do? I believe my company has done that becuase Wage 4 salary was too high compared to what I am currently getting and hence they would have applied for Wage 3.

Thanks for your time.
