<p>Thanks for your good advices, Fallenchemist and many other CCers. I called Wash.U. last Friday. According to a travel agent from Wash.U., it costs about $1000 these days, and they can reimburse it up to $300. Perhaps, I have to pay the deposit and visit after May 1.
BTW, “There are a few grammatical errors in it for someone so smart”: Not trying to argue, but this is not an English class, and not every smart people (I have never said I am smart on this thread) need to be good at grammar.</p>
