In both the Supplemental Security Income (SSI) and Retirement, Survivors, and Disability
            Insurance (RSDI) programs, we rely almost exclusively on self-reporting to determine
            when a material absence from the U.S. affects payments.  Depending on length of travel,
            citizenship status, and other factors (including the country of destination), we may
            require claimants, SSI recipients, and RSDI beneficiaries to report certain periods
            of absence from the U.S.  When individuals do not report their absences timely or
            at all, improper payments may occur.
         
         Our Inspector General has long recommended that we improve our controls in this area
            by using travel data instead of relying on individuals' reports. Furthermore, presidential
            budget requests since February 2016 have recommended government-wide use of foreign
            travel data to curb improper payments in Federal programs.
