I will suggest that you check out the admissions web pages of
the various institutions you are interested in to see what is
required for application.
You will be pleased to learn of the new tuition charges @
Harvard and some other Ivy League schools for undergraduate
students. Should you parents earn <US$120K annually,
tuition is 100% free. Between US$120-180K, you pay 10% of
their annual income. I am unsure if this applies to
international students but I would not be surprised if it does.
In regard your particular question, I have provided you a
response via private mail.
