Considering a move from the USA to Germany. Got any tips?

Hello,
I'm a college student here in the United States. But I've been wanting to move to Germany, specifically Berlin.
I would like to know what steps are the most important to take and also what type of circumstances I may expect.
My intention is to move to Berlin, study at any university and work my way up. I know it could be challenging, but I'm willing to make changes in my life.

Any advice is very welcomed !
Thanks.
