take on it. 485 is to check if an applicant is admissible, for example, out of status, serious disease, committing crime, and etc. All adjustment applicants need file 485 no matter what basis of their immigration petition, such as EB, FB, asylum, refugee, and etc. 140 is just one of them designed for EB immigration. At 140 stage, CIS check if a sponshor has the ability to pay (NIW, EB11 except), and if the beneficiary meet in capability the requirement of the proposed position. However, two processes are highly related. At 485 stage, CIS also checks the validity of the underneath 140. The elimination of 485 involves not only EB immigration, but the entire immigration policy as a whole
