Of course. I am just trying to give you a bit of support for how to talk to your parents. If they were able to go to school in their home country, that would have been a lot cheaper (even free in many countries because they only take the very best students).
One thing that we are doing for my son, to decrease costs, is having him take credits locally at a community college for classes not important to his major. That will let him graduate early so we will save a lot of money doing that. There are ways to save money even attending and graduating from an elite school.
But if your parents will not start a dialogue about the money, I am not sure where to start. They will have to give you financial information or do the financial aid forms themselves, or you will get no financial aid at all. Even merit aid sometimes requires financial aid forms to be filed.
