File I140 in PP. Sathi, yeti tada aisakyau, 1235 ko anhuar nahera.. khurukka PP gara. Benefi: You would know early about what is going to happen to your entire process. I140 approval means, u can't switch employer after six months of I485 receival. Nowadays it takes more than 8 months for regular processing of I140. Do u really want to wait that long yo know your fait? PP gara . Approval Liu, dhukka house. I have followed these cycles for many years. I have seldom heard of I485 getting denied after I140 is approved. But I know numerous case where I140 was denied.
