Because your wife is a citizen, you may file i130 and I -485 together at the same time. Although it is recommended that you maintain your current status , once you get the receipt of I -485 you don't need to maintain that. Even if you lose your status, it does not really matter. About employment , check ma kam gareko bhaye it is better not to lie , it will be forgiven for adjustment applicants in case like yours. About processing times, 5 months jati lagcha . Just near the completion of my case . Good luck .
