I130，妻子在国内，怎样的材料证明婚姻真实性？

结婚证，公证书都办了，结婚请客照片可以算一个。看130要求以下：

(1) Documentation showing joint ownership of property;
(2) A lease showing joint tenancy of a common residence, meaning you both live at the same address together;
(3) Documentation showing that you and your spouse have combined your financial resources;
(4) Birth certificates of children born to you and your spouse together;
(5) Affidavits sworn to or affirmed by third parties having personal knowledge of the bona fides of the marital
relationship. Each affidavit must contain the full name and address of the person making the affidavit; date
and place of birth of the person making the affidavit; and complete information and details explaining how the
person acquired his or her knowledge of your marriage; or
(6) Any other relevant documentation to establish that there is an ongoing marital union.

因为人没有签证过不来，小孩也还没有，1），2），3），4）都没有。结婚照片可以算一个6）。5）的话当然可以找人写，需要专业翻译还是自己翻译 就可以了？这边的人写的话，因为不太可能认识我太太怕是没有说服力。谢谢！
