You can do it through the exchange program at IESE!
About 65 people out of 210 (MBA2007) did exchange programs, so I think it is not too difficult with nearly 1/3 of the class going...(merits of a small MBA, less competition in jobs and things like this)
So
1) IESE is relatively easier (for Taiwanese) to get in compare to US top 15 MBAs
(refer to http://www.formosamba.com/phpBB3/viewtopic.php?t=23781)
2) IESE offers excellent career opportunities to Taiwanese
(refer to http://www.formosamba.com/phpBB3/viewtopic.php?t=23781)
3) You can still get to study in US top MBAs (see below)!
I. Wharton(1)/Kellogg(6)/Columbia(6)/MIT(2)/Chicago(4)
II. Berkeley(4), Duke(5), Cornell(4), UCLA, Tuck(5), Michigan(4), NYU(5), Virginia(4)
Number in brackets are the spaces available for IESE students this year. 55 spaces for 216 students.
Of course the reverse is also true, for example I am sharing my flat with an exchange girl from Columbia atm.
Attached is the full list of exchange MBA programs, you can also confirm from web site.
