You already answered your own question since you already stated you know someone collecting SSI who has autism/aspergers.
Suggest that you speak with an attorney who deals only
in Social Security Disability cases to determine what your options are.
If you do, ask what the backlog status is in your state. Some states have a backlog from months to years from the initial filing>denials>appeals>reconsideration>h earing>final approval>$$$$ & that is if you win your case.
So, if you even consider filing for SSI, I would HIGHLY RECOMMEND
that you file immedialy.
Are you a high functioning asperger person (high IQ)?
