我是公民，已經申請我的兩個姐姐和弟弟移民，我的問題是：
1，我申請她們的時候是單身，現在已經結婚了， 怎麽樣去通知移民局這個變化？
- 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的問題應當怎麽樣回答？
-What are these questions specifically or what Items in what Part of I-130?
