FAFSA deadline: the date you submit it online or the day it is processed?

My state deadline (california) is march 2 and i just submitted it online today. I could not use a pin to sign it online so i printed a signature page and im going to mail it. Its probably not gonna get there and processed by march 2. So my question is will they still count it as on time because it was submitted online on time even though the signature was late?|||Yes it will still receive it even tho the deadline has past as longest your fafsa is I'n record they will accept your signature page
