The Supplemental Security Income (SSI) program is a crucial support system for vulnerable citizens in the U.S. However, beneficiaries must adhere to strict rules, as any breach could lead to suspension of payments.

Social Security's May payment schedule is normal for most recipients. But Supplemental Security Income beneficiaries will get two checks this month.

May’s Supplemental Security Income payment, worth up to $967, will go out to millions of beneficiaries in two days. The next SSI payments are scheduled to be distributed on Thursday, May 1. SSI payments are given to people living with debilitating disabilities that affect their income, according to the Social Security Administration.
