i-864 添表问题

8老师，我看见你已前的一个回复。是回答为父母申请绿卡的。

i-864 是否要给父母分别准备一份？
-Yes.

如果是，那么在填父亲作为 principal immigrant的864时，在part 3还要不要填母亲作为family member 1？
-No.

我们家有我，我老公，一个孩子，我父母，我的问题是：Part5 Sponsor’s Household Size

1. Provide the number you entered in part 3, 我填 1 （这张表是为父亲填的，part3 里母亲 not counted as family member as you suggested above)

Person not sponsored in this affidavit 

2. Yourself,我填 1 

3. If you are currently married, 我填 1 

4. If you have dependent children, 我填 1 

5. If you have any other dependents, enter the number here. 在这我需要填 1 吗？母亲 was not counted as family member is part 3, 她需要counted as my dependent 吗？

谢谢你。
