Allows people who could not file for Social Security between January 20, 2025 and January 19, 2029 because of an "undue hardship" to be treated as if they had applied earlier, waives certain disability waiting‑period rules for that period, and directs the Social Security Administration (SSA) to identify affected individuals and set up a way for them to notify the agency. It also requires the Comptroller General to report to Congress on what SSA did from January 20, 2025 through January 20, 2029, how beneficiaries and customer service were affected, and recommendations to repair any harm.
