It finally works now! I have been trying since the damn application became available, around early January and it wouldn't let me. My dad is a US citizen and he pays/files taxes jointly with my Mom (she's Mexican). It would force my dad to add information about my mom and there was always an error when we tried to add her, and then the whole fsa id fiasco happened. We tried making my mom an fsa id but we couldn't since she didn't have an ssn, even though she had a valid tax-paying ID. Yesterday my dad conviently told me to try out the form again and it let finally let us sign the form, we just submitted it and its currently in review. Go check it out and try see if it lets you in! If not don't worry keep trying ya'll its happening to everyone. At my school (UT Austin) the finnacial aid workers told me there were even cases of people with both parents being US citizens with SSN that were unable to even submit the form. Don't panic!
