Eligibility is based on income and a lot of places are only open one or two days a month. Around here I am pretty sure they are open one day a month.
If you live with your mother/father/boyfriend, whatever, it goes by the combined income (and rightfully so). A friend of mine made like $8.00/hr and her boyfriend made $10/hr and they weren't eligible. So if your parents make pretty good money and you live with them then you probably won't be able to get it. But all areas are different and it is hard to tell.
If you need help then it is definately worth signing up for as that program was designed for women who need help.
