谢谢8老师，那么接下来：
1) NVC会寄地址确认信(即DS3032)， 是直接寄给受益人（我妻），还是寄给petitioner(我)？
-Normally it is sent to you. But this form needed to be completed and signed by your spouse. If you do not hire a lawyer for your case, you can be the agent appointed by your wife in the DS3032. Thus, NVC will contact you conveniently.

2) 在后面某一步会要求受益人（我妻）提交无犯罪记录公证。她是持加拿大枫叶卡的中国公民，这两年大部份时间在加拿大居住，偶尔间或回国一趟。那么，她需要出加拿大的无犯罪记录公证还是中国的，或者两者皆需？
-She needs to get this document from both China and Canada.

3）在受益人提交DS230时，会要求提交收益人的护照扫描页？那么，护照的第一页主信息页就够了吗，还是需要整本都扫描提交？
-She just needs to provide the passport when she is interviewed for the visa in the US Consulate.
