I think a few more details need to be put forward before any of your questions can be answered.
Are you currently attending a college or university in Illinois?
Do you intend on staying at the University of Hawaii at Manoa for a long period of time? Will you receive your degree from here?
There is also Housing available for the winter vacation at UH. If you want to have housing at UH for the summer, you will have to attend summer school.
I also live in a house that has rented rooms. It is a 10 minute walk to UH - Manoa. There is a possibilty a room might open up at the time you need it.
Roguevalley mentioned a possible reciprocity agreement between Hawaii and Illinois. There are special relationships between the University of Hawaii and other Western US State Universities. This network falls under the acronym of
WUE, or Western Undergraduate Exchange. Many students who take advantage of the WUE program have their tuitions slashed up to 150 percent. Unfortunately, Illinois is not listed as a participant in the WUE program. Call the University of Hawaii to see if there is a similar program for Illinois.
Yorkiemommie mentioned the
East-West Center. If you are studying Asian culture, politics, and history, this is one of the the best places to be (this is where the parents of Barack Obama met).
The Church of the Crossroads is definetly a huge Democratic Hangout. It was a refuge for those who resisted the draft during the Vietnam war. I also cooked food for the homeless here when I was a participant with Amnesty International.
One other thing - if you are accepted to the University of Hawaii, make sure to turn in your Housing application on time or well ahead of time. If not, you will definetly be in one hell of a shitstorm. Housing is extremely tight at UH and if your application is late, you will automatically be put on the waiting list (meaning you will NEVER get housing). Being that you are from Chicago, you will most likely get housing at UH (granted you turn in your housing application in on time).
There is a large variety of Japanese exchange programs from which you can choose at the University of Hawaii. No problem about that.
