Thank you for the reply, from what I have gathered I have to put home country as country of education and {by correspondence} is only for online and distance learning.On my new application I put Brazil as country of education, not USA. And added an LOE explaining the misunderstanding of the cancelled application.
At what stage is your application now? Was your MBA a full time one? Do you think we should provide any evidence from local institutions of study as well, in addition to the university in USA in your case?
