No Social Security for Illegal Aliens Act of 2023

This bill amends the Social Security Act to exclude wages earned and self-employment income derived from unauthorized employment in the United States from being counted toward Social Security credits. It directly affects undocumented immigrants who work without authorization, preventing those earnings from contributing to their future Social Security benefits. The law changes existing Social Security rules by adding specific exclusions for "service performed by an alien while employed... not authorized to be so employed" and similar self-employment activities. These changes apply to all wages and income earned before, during, or after the bill's enactment, with Social Security recompiling existing benefit calculations to reflect the new rules.
