Yes, I have a problem too. Foxrac, thanks for this!
Well... Before I got my first job, I didn't apply for SSI or SSDI or anyhting. I depended on my mom's money for a while cos I didn't want SSI or anything. When I got my job in 2005, I never asked for SSI or SSDI and I prefered my own paycheck that I worked for. Last summer, I quitted my job and I still had my money in paycheck until it was almost out of money. Now I applied SSDI last Fall and while I am still seeking a new job... I didn't know until I got a mail from SSI. They claimed that I owned them more than five thousands dollars from 2006 to present. That is so bull!! I never apply it for that until Fall 2008.

At the first thing on my thought, I thought it's a spam or something. So I talked with my mom and told me she will ask for some help. We hoped it is just a spam so I keep it as in case... until I saw this... I guess my mail is not a spam by then...
But but but why I have to pay over $5,000 to SSI place from 2006 to present WHEN I don't apply it until Fall 2008??? I don't understand.

Next week, I will try to meet in person at the place... to find out what it is. Sighs.
