我的朋友B2現在準備交485，她的女兒剛20歲，在讀大學，可以一起申請嗎？
-No. Her mother and her step-father's marriage has to occur before she turned 18 years old so that she can be qualified for the GC application under her step-father's sponsor.
我過去幾天問過關於她的事，得到熱情的幫助，再次感謝，現在準備寄出所有的材料，包括485，雙方的g325，和130，再有就是雙方的身份文件象結婚證，出生公證啥的，請幫我們看看還缺啥嗎？
-Also need I-864 with support documents of I-864 such as Tax return/W2, etc.
