我是公民，已经申请我的两个姐姐和弟弟移民，我的问题是：
1，我申请她们的时候是单身，现在已经结婚了， 怎么样去通知移民局这个变化？
- You or your sister/brother can add their family members to the list in their NVC account online after you create it when NVC contact you in the future. See "How do I add a derivative family member to my case?" at this link:
2， 在I-130 表格中，D1， D2的问题应当怎么样回答？
-What are these questions specifically or what Items in what Part of I-130?
