Supplemental Security Income Equality Act This bill extends the Supplemental Security Income (SSI) program to Puerto Rico, the Virgin Islands, and Guam. (When Congress created the SSI program in 1972, it excluded these territories.) This bill also eliminates a limit on payments from various Department of Health and Human Services programs to the territories. The Social Security Administration may waive or modify statutory requirements relating to the provision of benefits as necessary to adapt the program to each territory.
