Are you from NYC at all? I’m volunteering to help the migrant families that have been assigned to my child’s public school and after they got their NYC ID they are eligible for free healthcare for which they have signed up (both kids and adults), just like any destitute person in NYC, you don’t need to be a permanent legal resident or citizen to be covered if you’re destitute, just a NYC resident which you can prove with your NYC ID which in turn only needs proof of address. I’m not passing judgement for or against, but while the country may not provide Medicare or benefits the city certainly does.
