When is the employer bound to pay the prevailing wages as determined for an LCA and if the applicant is already working in the sponsored position. I have an H1B which was renewed recently, but my LCA was filed in March of 2008. Hence there were three wage determinations that were done for me - First one at the time of the initial H1B filing, second one at the time of the Labor for PERM and third one for the renewal. So at what dates does the prevailing wage come into effect as they happen to be different every time.
The employer is obliged to pay you the H-1 renewal wage now and the PERM wage after you get the GC approval.
