Your background is compelling, especially residing in three different countries. The kind of cultural experience you would bring to any school could not be matched.
You have a decent GMAT score and an average GPA. Your undergraduate background is unique. The brand name of the school may help you in making a good first impression.
Your work experience sounds really good. Please explain the results achieved at workplace. Did you have a lot of leadership experience? Were you felicitated with awards from your employers?
Your extracurricular activities are outstanding. You seem to have displayed significant leadership ability here especially as you broke records in donation collection, and the event with such large number of attendees.
Your long term goal post MBA is clearly aligned to your past work experience. This would certainly help.
You should apply to HBS, MIT, Chicago and Kellog.
As you have significant international experience, I would suggest you to apply to INSEAD and LBS. These schools are ranked among the top, and value international experience.
