If it's changing so much my first instinct would be that I'm not standing in the right lane and look for another one. E.g. aren't you supposed to get a green card if you overcome a certain amount of US local investment? As an experienced businessman maybe that's a better way. Or maybe a politician could grand you a green card if you do enough favours for him (that's how I assume it works in some countries). The most obvious way often is not the right way.
