As long as your initial entry into United States was with a visa, it is important that you do not leave the US but instead, have your daughter file the Form I-130 petition immediately she turns 21 years old. If you are eligible to adjust status in every other respect, you should be ok. However, it is strongly suggested that you hire an experienced attorney to assist you in this regard.
