state sponsored health care that you used before the public charge rule effective date has no impact at all. it could be an issue if you continue to use it after the effective date (which was on 2/17 or so not sure). this wont solely deny your green card. IO will evaluate a lot of things like your age, employment, education, income etc. if these over weighs, you can still be granted a greencard despite having state sponsored health insurance.

but to be on a safe side and if you are a healthy person, you can give up any sarkari insurance. but if you dont for whatever reason its not gonna impact much as long as you have good income, good education at the time of your GC interview.
