If you apply for federal financial aid and you aren't an "independent" student...?

Nope. Just because they won't give you their info, does not make you an independent student. I went through the same exact thing with my fiance. His mom would not give her info and he was not over 23 at the time so he could not get financial aid. The ONLY factors that make you a dependent student are if you are married, over 23 or have a child have provide for over 50% of that childs needs. Your parents not wanting to pay for your college or giving you their info does NOT make you a dependent student therefor you application will not go through with out their information if you do not meet the above qualifications.
