Although there are some exceptions, generally individuals must reside in one of the 50 states, the District of Columbia, or the Northern Mariana Islands to receive SSI benefits. The Northern Mariana Islands became a U.S. territory in 1976 (after the SSI program began) and the covenant establishing its territorial status included eligibility for SSI. The territories of Guam, Puerto Rico, and the U.S. Virgin Islands are eligible for federal grants to support the "aged, blind, and disabled" but residents are not eligible for SSI. In April 2022, the Supreme Court ruled (in United States v. Vaello Madero) that it is constitutional to exclude residents of Puerto Rico from the SSI program, as the territory does not pay most federal taxes.https://www.supremecourt.gov/opinions/21pdf/20-303_6khn.pdf
