Hi Tsmarket,
Thanks for writing in and sharing those details. You have some really interesting international exposure and work experience which should play well with in your applications. I do think being from Mexico gives you some leeway on your GMAT score, as scores from that region -- by reputation -- tend to be lower, but that doesn't give you an automatic "pass" on your GMAT either.
I would rate HBS and Stanford as reach, Columbia and Berkeley as near-reach, and the rest as competitive.
Best of luck,
Daniel Richards
