SC is not moving forward with Medicaid Expansion.
This means no Medicaid if you are not disabled, have no children.
SC does not have a General Assistance program, cash assistance for single individuals.
Housing help for single individuals is extremely difficult, I doubt it is available in SC, if it is, expect a multiple year wait.
There are many welfare programs, but not available for those without children, elderly or disabled.
States have no money for work programs for people without their children in their home.
Food stamps it is.
If there is something you "heard about", I can look it up for SC, and tell you why you are not eligible.
I have been a welfare eligibility worker in two states, and am well versed in researching specific programs in specific states.
The vast majority of welfare money goes to the chronic users of the system and those with children where the adults do not want to work, although certainly some of the adults do want to work, but they are a minority.
The rule of thumb is 'no children - no welfare', although there are many exceptions, food stamps being the big one.
