The Social Security Disability Insurance program (SSDI) and the Supplemental Security Income program (SSI) are federal programs intended to help people who are unable to work due to medical disabilities. Most people are initially turned down when they apply for Social Security disability benefits, even though they are disabled and they do qualify for Social Security disability benefits.  Therefore whether you are applying for Social Security disability or SSI, or if you have been denied this benefit you need to consult an attorney who knows the process, paperwork, and detailed rules and regulation on Social Security disability.
