This bill seeks to significantly restrict eligibility for federal public benefits by prohibiting all aliens from receiving them. It achieves this by amending the Personal Responsibility and Work Opportunity Reconciliation Act of 1996, specifically Section 401, to state that any alien is ineligible for any Federal public benefit. The legislation expands the definition of "Federal public benefit" to explicitly include cash assistance and repeals existing provisions that previously allowed for limited eligibility of certain "qualified aliens" for federal programs. Furthermore, it eliminates the statutory definitions of "qualified alien" and other related terms, effectively removing any distinction for benefit eligibility among alien populations.
