she has like 10 days to report changes in her income though. but if she's SELLING her WIC then yeah she could be in a lot of trouble for that. I think it's like 1-3 yrs of denial if she could qualify again for it.
That's terrible and she should let them know she doesn't need it so that money can go to someone else who really needs it. That is shady and I would report it too. That's messed up that she is selling them, she is in a mess of trouble.
