The Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996 radically reformed the US public welfare system by replacing federal entitlement programs with Temporary Aid for Needy Families (TANF). Federal TANF regulations emphasized strict new work requirements and time limits on cash assistance. PRWORA also impacted legal immigrant eligibility for public benefits by restricting access and increasing support requirements. The history of US immigration policy reflects conflicting views of humanitarianism versus protectionism/exclusion, with the latter predominating since the late 1800s through discriminatory policies. When constructing PRWORA's Title IV, the perception that immigrants were a "welfare magnet" prevailed, seeking to remove the welfare incentive for immigrants entering the US.
