This bill seeks to significantly expand access to federal public benefits and services for lawfully present noncitizens. It achieves this primarily by repealing several restrictive provisions from the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) that currently limit noncitizen eligibility for various federal programs. Additionally, the bill reverses recent changes made by Public Law 119-21, restoring eligibility for programs such as the Supplemental Nutrition Assistance Program (SNAP) , Medicaid , the Children's Health Insurance Program (CHIP) , and Medicare for noncitizens. The legislation broadens the definition of a "qualified noncitizen" to include a wider range of individuals, such as those granted Deferred Action for Childhood Arrivals (DACA), special immigrant juveniles, and individuals with pending U-visa applications. It also ensures that states cannot deny participation in child nutrition programs based on an individual's citizenship or immigration status. Furthermore, the bill makes conforming amendments across various acts, including those governing housing assistance and Medicaid, to align with the expanded eligibility criteria and replace the term "alien" with "noncitizen." A key provision restores and expands the allowance of the premium tax credit for certain lawfully present noncitizens. Specifically, it creates a special rule for low-income, lawfully present noncitizens who are ineligible for Medicaid due to their immigration status, treating them as having an income equal to 100 percent of the poverty line for tax credit purposes. Federal agencies are mandated to issue guidance within 180 days of enactment to implement these changes, with the amendments applying to services furnished 180 days after such guidance is issued.
