NYU, NU, Cornell, UCLA, GTown you would stand a chance. Chicago will be difficult.

Try for Columbia also. You could stand a better chance there also.

I think Columbia accepts applicants from different backgrounds with a variety of work experience. You said that you have done some internships in different firms that might help if you can demonstrate the type of work you have done there. Additionally, I think as you are from Belgium that might give you an edge over other applicants who are mostly from the US. My opinion is that you should give it a try.

The rest of the list seems fine to me.
