SSA looks at two categories of eligibility criteria for SSI and the individual must meet both categories to qualify. SSA will first determine if an individual meets the nonmedical eligibility. SSI is a means tested program so a person must qualify based on limited income, assets, and resources. Once a person meets the nonmedical eligibility criteria, SSA will review the application to determine if an individual meets their definition of medical eligibility. The medical evidence has to show that the person is unable to work and earn $1090.00 per month or $1820.00 per month for individuals who are blind in 2015.
