Do the faculty in business schools take students for research purpose? Most of the science students are supported by research grants secured by faculty.

If you have already short listed your schools, you may want to contact the department of those schools and ask them if they support international students (assuming you are an international in US) financially. If you need financial support, you don't want to send your application to the school that doesn't give you a cent.

If I were you, I would ask some questions to myself like:

• Do I need financial support or not?
• Does the school provide financial support to international students?
• How many international students does the department take every year?
• If that particular school interests you, it would be nice to communicate with the current student (Nepali or Asian) who can give you better perspective..
• Does the department offer what I want to pursue academically?
• Is my GRE/GMAT score competitive enough? (You can always look at the statistics of their accepted students. The score does matter when there will be many applicants with 4.0 GPA competing for limited spots. Last year, when I was traveling around for admissions interviews, I met some applicants with 5-10 years work experience but now going back to school. Blame current economic situation).
• Does location of school matter?
• How good is alumni network? (It helps when you enter into job market)
• Does the school ask you to come for the interview with the faculty?....

Anyhow, it really depends what you want in a graduate school. You seem to have good GPA. I know it is long and painful process, but it will worth at the end.
