CSU financial aid acceptance deadline?

<p>Hey everyone, is there an actual deadline to accept financial aid at CSU's/UC's? Specifically CSULB/CPP/UCI. I got my financial aid pack at CSULB but I didn't get an acceptance from CPP yet (they're taking forever). So is there an actual deadline to accept the financial aid (Pell/Sub. stafford loan only) or can I just accept it later after I submit my admissions deposit?</p>
