My PD date is Dec 2007 EB2. I got I-140 approved in 2008. My salary was above prevailing wages from 2006-2008. But due to some economic and personal reasons in the last two years my salary was below prevailing wages (2009-35K and 2010-45K). This year (2011) it is now back upto the prevailing wages. Everything else is fine. Now what are my chances just because of salary reduction my I-485 getting rejected. can I show that I was on unpaid leave?? really nervous about this. any guidance would be highly appreciated.
