My parent accidentally added a middle initial when he didn’t have one, and he didn’t capitalize his name. And the wrong mailing address (we just moved). He got matched with the SSA though, so his ID works for now… If I submit the FAFSA with his FSA ID signature, can he change his FSA ID info after? Would it even match with my info? We can’t change it now since it disables us from using the ID for 1-3 days.
He got matched with SSA, so his FSA ID is good. You should submit the FAFSA with his ID signature, and it should match just fine. Mailing addresses change a lot, so that is not an issue. Just complete the FAFSA (tomorrow or after), sign it with the FSA ID, and submit. You can change info later on the FSA ID, if you need to do that.
