我建议他们千万不要申请转身份到B2，留在美国等女儿21岁就行了

1. 完全没有必要，浪费钱。美国公民的配偶、父母、和未婚21岁以下孩子是Immediate Relative类型。无论无身份多少年都不会影响他们Adjustment of Status（就是在美国境内申请绿卡的过程）。无论黑多少年，如果不离开美国就没有ban，不需要豁免或任何其他特殊手续。

2. I-539 instructions要求申请B2身份延期和转身份到B2的都需要附上一个声明，其中要说：

If you are filing for an extension/change, you must file your application with the original Form I-94 for each person included in your application. In addition, you must submit a typed or written statement explaining in detail:
B. The reasons why your extended stay would be temporary, including what arrangements you have made to depart from the United States; and

如同他们打算在这次逗留期递交I-485，那他们就不打算他们的stay是temporary的，也不打算depart。所以如果写这样的声明就是说谎。千万不要跟移民局说谎。

所以申请转身份到B2没有好处，只有坏处
