While most information can not be changed on the FAFSA form, some information must be updated if it changes. We have relevant information on the difference and how to update FAFSA information.
In addition, I need to find out about renewing my FASFA form.  In a hypothetic scenario, how would I do a renewal to change information on my form?
No problem. Just Login into your account and select FAFSA renewal once there. It all will develop  automatically.
You mean i just sign in there after that, all i have to do is submit the form?
