This bill, titled the "No Social Security for Illegal Aliens Act of 2025," seeks to amend the Social Security Act by preventing certain earnings from being creditable for Social Security benefits. Its primary purpose is to exclude wages earned for services and self-employment income derived from a trade or business by aliens who are not authorized to be employed or conduct business in the United States. The legislation modifies Section 210(a)(19) to specifically exclude service performed by an unauthorized alien from creditable wages. It also amends Section 211(c) to exclude self-employment income derived from functions or services performed by an unauthorized alien. These amendments are designed to apply to all relevant earnings, whether accrued before, on, or after the bill's enactment date, and mandate the Commissioner of Social Security to recompute primary insurance amounts accordingly for benefits paid in months after enactment.
