According to the UTD Top 100 Business School Research Ranking, there are some Asian (Hong Kongese) universities that rank higher than many US and Canadian universities. What are important factors to consider for international students in case of Ph.D admission especially with respect to funding, region and ranking of the university?
And with respect to future career, networking with academics, publication, shouldn't international students aiming for a Ph.D prefer the US first?
One of the most important factors is in which country you plan to work after getting your diploma. E.g., if you plan to work in France, some French diplomas are just as valuable as "top" US schools.
