What do you need to move permanently from the uk to the usa?

My friend and I are wanting to move to The USA permanently but we don't know what we need or how easy it is to get there. We are still in school at the moment but we are making future plans as we both have a dream to live out there. I have an American friend out there, would this be in our favour if we wanted to move in with him? This is very important to us and we would really like an answer :) Thank you! :)
