Hi there,
Ok, so you have some strengths and weaknesses and unknowns here...
Strengths:
GMAT score
Less-common nationality among applicants
Less traditional background
Teaching/communication skills
Language skills
Weaknesses:
Undergrad GPA (side note-- does that mean '4.0' GPA in masters?? which does help)
Potentially confusing 'story' or path...engineering, to arts, to teaching, to translating, to hedge funds?? Can sound scattered and unsure.
10 years of work experience puts you on the extreme end of years of work experience--i.e. do you truly need an MBA at this point?
Unknowns:
Examples of leadership? Making an impact? Achievements?
Community involvement?
Essays/recommendations/interview
So based on the above, it's hard to give an overall assessment with many unknowns. I'd say the top 20 will be challenging, but WITH strong essays and some kind of compelling case of why your story is so varied and why you really need the MBA and how your next steps will work etc, you could apply to 1-2 as 'reach' schools, then a few outside the top 20.
