Thank you all!!
I didn't make a decision yet... because all the options look good to me. Lots of professors recommended me to go NYU because of the high reputation(especially in this country). However, the curriculums in CMU attract me as well...(I am interested in management and advertising and actually, I worked as a junior copywriter at popular ad agency for 6months)
I think I have to plan out my future first so that I can choose the best school for me.
Anyway, I will send my letter to one of these universities in this week!
