I'm not from the US, so forgive me for what is probably a dumb question, but how is an illegal receiving money for food, rent, and healthcare? Don't you need documents (aka be legal in the country) for that?
There are food banks and stuff like that, but that's usually from charities.
That’s how most undocumented people in the country survive: by working for employers who are breaking the law.
In terms of undocumented individuals benefits, that’s a common and almost entirely false claim.
While it is a complicated space (because of State vs Federal), the vast majority of “Illegals” are not eligible for the vast majority of benefits in the United States, with the exception of some emergency services.
There are some exceptions for victims of human trafficking and there like.
