it is going to take a lot and I really mean a lot of time if you are above 21. I think you will have already completed your college education way and way before a visa becomes available.
Currently, only 26,000 visa becomes available each year for all the people around the world in your category. So even I 130 gets approved way earlier, you have to wait in the queue to become a visa available for you so that your I 485 gets approved.
