what are my moms options? her status is "overstayed" she's been in us for more than 10 years. her master calendar hearing (3rd) is in one month.

If I understand your fact situation clearly, you are her only relative and you have four children of which three were born in the US. Although your mother has been here for more than 10 years, she would not appear to be eligible for the relief of cancellation of removal as none of the US-born children are hers. She also does not appear eligible for the President's 11/20/14 executive action relief for parents of US citizens or permanent residents as she does not appear to have any. I suggest that if she has not already tried it, her attorney should send in a request to the government attorney who has her case for prosecutorial discretion. In such a request, she should list all of her unfavorable as well as favorable factors as those will be the basis upon which the government attorney will make a decision.
