actually i am confused because i wanna study MBA but my major study t bachelor degree is Computer information systems and minor is business administration , so i am in between of computer science and an MBA what subject should i choose ?!!!In my embassy guidelines they were very clear about this point:
(4) Major Field of Study:
The field of study must be in the area in which the applicant has studied (or is now studying) or is related. An applicant must choose maximum 3 universities where s/he can study and research the field of her/his choice.
I suggest you read the application guidelines thoroughly as they can vary slightly between embassies. In general it is not possible to apply for a subject you have no related degree in, however passionate you are about it.
