Some foreign-born Californians are canceling their Medi-Cal coverage or declining to enroll in the first place, citing fears of a Trump administration crackdown on immigrants. Among those dropping coverage are people in the country legally but concerned about jeopardizing family members who lack permanent legal status, according to government officials, immigration attorneys and health care advocates. Others worry they will be penalized in the future for using public benefits such as Medi-Cal, the state’s version of the federal Medicaid program that provides health coverage to low-income residents.
