If you TRULY cant pay, find a way. There is no way around the deposit as it helps guarantee your seat...plus that may or may not be applied to your first semester fees (not sure at NOVA).
You stated you live with your parents..asking for $1K is not bad when your taking the other $119K with loans..it is an investment into your education. Get a job for the summer and work to pay them back, go door to door asking for support, talk to friends and family..you maybe surprised with the response you get....
as for loans, everyone is right with no subsidized..so either fill out FAFSA (have you done this?) and be prepared for the whopping 6.8% we unlucky folk are stuck with or go private with a cosigner to get a lower rate. Either way things will be sent to the school and dispersed sometime the first month of school.
