This has been the case since the 1970 case Goldberg v. Kelly
Yes accurate, it's three months rough turnover with appeals taking up to a year or more.
As for the preparing beforehand? I know almost for a fact Chris is on SSDI as SSI is not often given for disabilities and the SSDI amount would negate his ability to get SSI income.
Chris has a lifetime of hard evidence for disability and 20 years roughly of prompted reviews for his case that he has "rule in favor for". Meaning they deem nothing has changed about his situation. If there is a loophole for preparing for this he would have great precedent for approval. That's about all I know. I'm not even aware if Chris knows that sometimes reviews for disability comes in or that he should be proactive with his only source of income. Bob/Barb might have just filled out all the paperwork for him.
What's more, his income isn't even that much. Bob was moderately successful, but they weren't rich.
Chris income might only be 1.5-2k dollars monthly and they are still paying mortgage on that house.
Assume 500 dollars to mortgage, 300-600 dollars on food. That doesn't leave a lot to work with.
He still has his utilities, he still has his debts, yearly taxes negate an entire months worth of benefits.
and he is still an autistic manchild to boot.
It's very terrifying just how much of Barb's own social security he was stealing from every month.
