太太拿绿卡的时间和孩子不一样，所以不能同时申请条件绿卡condition removal。
太太已经申请得到了收据，现在正在给孩子们办。有几个问题：
1. support materials用什么？用太太申请的全套material就可以吗，还是孩子要自己的material？如果是，哪方面的？
-Proivde the same documents as the onces for your wife including the filing fee, etc., but the child also needs to submit a full explanation as to why he/she are filing I-751 separately, and provide the copy of the child's birth certificate and your marriage certificate with the child's mother.
2. 需要孩子和继父的合影之类 的吗？
-Not need.
继父是不是需要给一个statement之类的，support孩子的申请？-Not need. The child's I-751 approval will depend/rely on your wife's I-751 apprvoal.
