EB-2 with salary less than Prevailing Wages

[qgc123]

Hi All,
My green is filed under EB-2 category. My current salary is around 6000$ less than Prevailing Wage from Department of Labor.
My Labor(PERM) and I-140 is approved.
Priority date is in second half of 2010.
What will happen to I-485 / GC stage as my salary is around 6k low than Prevailing Wage? When should be Prevailing Wage applied? Should it be now or at the time of PERM or at I-485 stage? What if my company denied to pay me required Prevailing Wages? What are my options?

You must be paid at least the prevailing wage when you get the green card. Otherwise, you can't get green card.
