Maria Elena Estamilla, 62, left, and her daughter Esmeralda Triquiz pose for a photo June 30, 2021, in Chicago's Pilsen neighborhood. Estamilla's last full medical exam was in 2015, and she sees no options for care as a Mexican immigrant without legal permission to live in the U.S. She's not eligible for Medicare, Medicaid or Affordable Care Act coverage. As a child care worker, she didn't have employer coverage. She can't afford private insurance.
