I was approved for SSI and SSDI following a hearing with an ALJ on Feb 25,2008. I had to go into the office on March 13th and answer alot of questions and was told I would receive SSI and that it would pay faster because it took awhile to figure up my SSDI benefits. I was also told that the backpay due from SSI was almost $22,000.00, but I would recieve it in 3 installments over the course of a year. I got a letter in APril stating that they had calculated my SSDI monthly benefit amount and it was low enough that I am still going to qualify for SSI(my SSDI is going to be $555.03 and my SSI was going to be $637.00, I know that will be refigured due to the new SSDI income) and will recieve both monthly, but that they may have to withhold my SSDI backpay if I receive SSI for the backpay period. My question is since I haven't actually recieved my SSI backpay are they going to withhold it from my SSDI? Or will they go back and recalulate my SSI and find out what they actually have to pay since SSDI is now saying they owe for that period as well and reduce my SSI benefit due to that. I know this is lengthy, but all of this is so confusing for me and I didn't have an attorney so I have no idea what i going on at this point.
