Yolibeth’s 4-year-old daughter scrambled headfirst onto a cushy leather love seat at their home near New Orleans and pushed a hairbrush into the hands of Miriam Romero, a health coordinator who works with the family. Romero placed the girl in her lap and started brushing her dark hair.

Yolibeth, a 38-year-old single mother who moved to South Louisiana from Honduras 15 years ago, watched them, smiling. The daughter is the youngest of five children living in this mixed-status household. Yolibeth and her two oldest kids don’t have legal immigration status, but the other three — ages 4, 9, and 13 — were born in the U.S. and are citizens.

All of her U.S.-born kids were enrolled in Medicaid at birth, which made it affordable for her to take them to the doctor for regular checkups when they were little. Her oldest two, ages 15 and 17, have never had health insurance, so Yolibeth relies on low-cost community clinics when she can afford it.

But now she worries that healthcare access for all of her children is slipping away. Yolibeth has been waiting for months to hear whether any of her children’s Medicaid renewal applications has been approved. She fears they will be denied because of a new Louisiana law targeting noncitizen Medicaid enrollees, even though she isn’t applying for herself. She worries particularly about her 4-year-old’s access to routine care and required childhood vaccines.
