How competitive is the admission process for an LLM at University of Chicago/Northwestern? I know they only accept about 50 applicants - are these mainly foreign students, or do you have a better chance if you are an Illinois licensed attorney?

What about DePaul/Loyola/Chicago-Kent?

I went to a 4th tier school, graduated in the top 15% of my class. I know I realistically don't have a chance at University of Chicago, but would I have a chance at DePaul or Chicago-Kent?
