我的朋友B2现在准备交485，她的女儿刚20岁，在读大学，可以一起申请吗？
-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.
我过去几天问过关于她的事，得到热情的帮助，再次感谢，现在准备寄出所有的材料，包括485，双方的g325，和130，再有就是双方的身份文件象结婚证，出生公证啥的，请帮我们看看还缺啥吗？
-Also need I-864 with support documents of I-864 such as Tax return/W2, etc.
