Gov. Andrew Cuomo said on Wednesday the state may sue the Trump administration if it moves forward with a reported plan to limit legal status for immigrants who have used public welfare programs or purchased health insurance.

The proposal, as reported by NBC News, would make it harder for immigrants to obtain green cards or legal status in the United States if they have purchased health insurance under Obamacare or used children’s health insurance, food stamps or other benefits. It’s an expansion of current rules that already consider some public benefits, like Social Security insurance, into decisions about legal status, NBC reported.
