She already qualifies as an independent student for FAFSA filing so no need for parental info (foster parent info is never required anyway). She will file FAFSA with only her own income/asset info and should follow the instructions for independent students. If she has little/none, she will qualify for maximum federal/state aid and may also be awarded some institutional grants. She will also qualify for Stafford loans in her own name and may be offered some Perkins loan money too. Beyond that, who pays the difference is up to her and her family to figure out. Hopefully she has applied to some schools that will be affordable!
