UCI, LEHIGH, PURDUE, RPI, OR PSU?

I got accepted from the schools I listed on the title, most of them were CS program, except lehigh is computer science and business. I have hard time deciding between UCI and LEHIGH. I always want to be part of silicon valley, as a matter of fact, this is one of the reason for me to study in the states.(I’m from China)
I’ve heard that IT companies do looking for students at UCI. But I am worried about the study environment, since there are lots of asians, chinese at UCI.
Lehigh, in the opposite, has very few Chinese each year, about 80. The CSB program is great, but I saw some graduates stated that most CSB students there end up on the east coast, like big 4 accounting on the wall street, for the best. I dont think the study environment will be the issue there.
Could you guys help me decide? Thanks a ton!!!
BTW, 2015 is a bad year for me. Having 2040 SAT/ 105 Toefl along with solid extracurricular activities, I only got accepted from 5 schools out of 22. I am pretty disappointed. -.-
