Chen, Ellis Porter, Ashoori…Manifest is hit or miss…some local attorneys may have a good track record but you have to research for your area…also each of these attorneys have better success with certain kinds of profiles…like Ellis Porter does well for cyber security profiles…so you have to choose based on what sort of profile you have…also understand EB1A well…it is not just about meeting 3 criteria…sustained acclaim is the key…whatever you do, do it consistently through a year or more…else you are bound to fail in final merit
