Thanks pyrhuss! I know what you mean but i still have some concerns. IHEID is with no doubt a great school, but for Chinese students, not so much. For one thing, from what I hear there does exist discrimination against non-EU students in the job market. It's not necessarily someone's fault, for we do have disadvantages in terms of languages, etc. So pretty much for sure i have to come back to my home country when i graduate, but i think the reputation of IHEID is kind of confined to Europe. For another, the courses in SAIS are more quant so i might be equipped with some "hard skills".
To be honest the money thing is the only thing that's holding me back from confirming the acceptance at SAIS. i can only hope this will turn out be a fine investment and that i can earn the money back before too long.
