In that case, you need to fill your fafsa form anyway and get in contact immediately with the financial aid office at the college or career school you plan to attend and then know what to do next.
You've got it. Selected Service is another concern I have. Is it necessary for me to register for Selective Service?
Yes, most male students need to be registered with Selective Service to receive any kind of federal student aid.
I'd like to know on what should I do with my FAFSA form if I don't have any communication with my parents for a long time?
