Is there financial aid for ex felon who is 64 yo, does not qualify for SSI, does have some work skills, who is clean and sober with no convictions or arrests
For 11 years?

There are education loans for felons, that's about it, but any money is tight for all people.
Some felons get jobs at halfway houses, rehab centers, and non-profit help groups for other felons, after volunteering for a while.
Does that sound possible for you?
