Hi sidceg,

U.S. and Canada are two likely countries you may consider, with Canada being faster and easier from emigration perspective. However, if you're looking at jobs in tech companies, you'll have a better shot from U.S. schools.

Since you're from a competitive applicant pool, your target schools shouldn't be off in terms of median GMAT score. Another thing you can keep in mind while evaluating schools is to look at their recruitment reports and see which of them have high recruitment % in tech industry and within the industry do top companies recruit there. Amazon, for example, recruits in large numbers at several campuses in U.S.
