请教关于公民面试要求带的文件

很快要去公民面试了，收到通知让我带很多文件。其中有三项我不太明白它的要求：

（1）Proof of marital union as well as proof of residence.

我的疑问：这是让我带有我和老公名字的 utility bills?

(2) Certified copies of birth certificates of all your children born in the United States.

我的疑问：带原件和复印件可以吗？还是要去银行办个 notarized copy?

(3)An original Internal Revenue Service form 1722 listing tax information for the past three years (call IRS toll free ar 1-800-829-1040), or copies of the income tax forms you filed for the past three years.

我的疑问：带会计师给我们的copy 可以吗？没有签名的。

多谢了！
