I’m a U.S. citizen who just got married to a woman from Mexico. She has three Mexican-born young children from a past husband. They all came to the U.S. a few years ago, on tourist visas. I want to help my new family get green cards, but I don’t have enough for the adjustment of status application fees – it adds up to hundreds of dollars! (Her parents are rich, but they don’t approve of me.) I’m working toward my G.E.D., but neither of us have jobs right now. Can we get a fee waiver so we don’t have to pay?
