先谢谢8老师！
我是US公民，想为父母申请绿卡，父母现在人在美国。我打算给他们分别提交一份材料。 有如下几个问题：
I-130:
If you are also submitting separate petition for other relatives, provide the names and relationship to each relative ? 是不是应该填 Yes, 然后填对方配偶的姓名。
-Correct.
relationship 就是 father or monther ?
-Put "My father" ("My mother").
Beneficiary's Employment (if applicable) 一栏，他们都退休17年了，我是空着，还是填"Unemployed", or "Retired" ?
-Just put "Retired".
I-864:
number of immigrants you are sponsoring: 我给他们一人一份，在每一份上是填1 or 2 ?
-Put "1" on each I-864.
Household size ?? 同样，在每一份上是填 2 还是 3？
-Also put "1" in Item 6 of Part 5. Thus, your total household size will include both your parents.
I-485:
Info about your Marital History: Is your current spouse applying with you ? 同样，在每一份上是填 Yes 还是 No？
-Say "No" becuase these two I-485 are not related to each other.
最后一个问题，在这些表格上，那些 "if applicable", "if any" 的问题，如果不适用, 是不是可以空着不填。还是必须要注上 N/A. 我的理解是可以空着。
-Leave it blank.
抱歉问了这么多问题，万分感激你的回复。
