really? the person got aproved for SSDI recently, Last September '06, has worked for 3 yrs. And nothing changed amount moving out/in different state. SERIOUS! 
I assume every office or coworkers are different. Like happened to me with my older daughter who is hard of hearing I applied for her, got declined. Later on, in same building but different co-workers, I applied for my younger daughter, she is deaf, I got approved, then they review my family and said my older daughter is eligible for SSI. I told her I tried and got declined-she was like HUH?! offered me to do again as appeal, then I got approved both daughters
Then guess what, they deposited into my bank acount, Direct Deposit, the amount of 9 months they owed, then in the letter said I have to owe them for that month cuz I got much amount for that month, huh, they gave me 9 months amount, just doesn't make sense, so after I spent all money to pay off 2 payments I told them I dont have money for next month they waived me.
