SSI recipients may have difficulty contacting SSA, reporting changes or understanding
                  and responding to our notices and requests because of mental and physical conditions
                  and difficulty communicating. They may also go in and out of temporary living arrangements
                  and homelessness without having a way for us to contact them. Indications of recipients’
                  difficulties may be known to employees and found in field office (FO) files and systems
                  records.
