No, undocumented immigrants (often called "illegals") are not eligible for federal SNAP (food stamp) benefits; federal law prohibits them from receiving these benefits, though their U.S. citizen children may qualify for assistance within mixed-status households, and recent legislation (OBBBA) further restricted lawful immigrants' access too. SNAP eligibility focuses on U.S. citizens, nationals, and qualified legal permanent residents, with strict rules and waiting periods for many non-citizens, while state-funded programs or other benefits (like emergency Medicaid for health) might cover some ineligible groups.
