If Miami is your dream school, go for. I think you might have a shot at some even higher ranked schools, though. Having a 3.7 average for your last two years is great. A 166 is a very solid above average score. Your work experience is very unique, I think. It shows that you are a mature person if you were able to be a successful journalist in 3 different foreign countries, and it also gives you a much more worldly perspective that not a lot of other applicants are going to have. It's been 10 years since you got booted from school, and you have clearly matured significantly since then. Miami should be a lock, and honestly if you are willing to spend the money (and want to go to a different school) then apply to a lot of schools in tier 1. You never know where you're going to get in.
