From Pomona’s website: The Admissions Committee takes financial need into consideration at the time of admission.
COA annually at Pomona is $75,000. The average aid given was $57,415. You can earn about $2000 a year with work study. Can you come up with the difference each year?
The competition from other Indian students is fierce. I’m not sure how much impact your research-based ECs will have. For example, having done summer research with an MIT professor isn’t more impressive than a kid who had to work all summer to support his family.
As mentioned, the acceptance rate is 7%. It’s even lower for international kids needing a lot of financial aid. I think you need to do more research and perhaps post all your stats so we can assess your situation a little better. Tell us how much money you need. As mentioned, Pomona is NEED AWARE.
