First of all - strong profile!
As far as I am with reading for what these schools are looking for I see you chances on the strong side with Haas.
Columbia seems to be overfed with finance and accounting and booth is starting a very intensive search for more internationality. You certainly have a chance at all three, which highly depends on interviews.
Let's start with the GMAT. In my opinion usually better to score higher in math. Concerning the points your at or above average for these schools, so no reason to worry.
University you attended before should give you a nice plus. Also the work experience adds up to a great amount. The essential part is, that you are able to tell good stories about the different times. Challenges, experiences...
Extracurriculars sound fine.
Limited international experience is certainly your weak spot (seems to be the only). Try to think of situations where you had an exposure to other cultures. This might even be teams where you were engaged that included a good mix. You need stories to tell here, because they will certainly ask you about his.
Overall: Don't be afraid. Good essays will get you the interview and I start to think this way: They're not looking to reject you - they try to find a good reason to accept you!
All the best
