What is the difference between Social Security disability (SSDI) and Supplemental Security Income (SSI)?
Social Security disability requires that the injured person pay into the system for 40 quarters, or 10 years. If you haven’t paid into the system for 40 quarters, then you may be entitled to Social Security Supplemental income. For example, consider a housewife who becomes disabled, a student who hasn’t yet paid into the system that much, or a young employee who hasn’t paid into the system for 10 years. When they become disabled, they’re eligible for SSI benefits.
