Thanks Guys. Ok, if I dont put it on Biographic info that asked for all the past works and as saan_dai suggested to submit copy of W-2 and I am sure all tax records (and USCIS might ask that for sure) , wont they find that our the employers that is not listed on biographic info is listed on W-2 or excess income in tax form and will ask for explanaition for lying... man its a mess.
