You need to figure out whether you will be considered an independent or a dependent student for financial aid purposes. Your personal assets will be treated more favorably if you are an independent student. If you are a dependent student, expect most of the 30K to go towards your Expected Family Contribution (EFC.)
You can start by visiting
FAFSA - Free Application for Federal Student Aid and clicking on the "Determine Your Dependency Status" link to figure out if you will be considered Independent, or if there is anything you can do to become one (which is usually very hard to do.)
