I got a letter from USCIS stating that additonal infomation is required for my I485 application.

1) "A photocopy of the Household or Village Registry reflecting the entry of the marriage" and
2) a photocopy of booklet issued by .....which contains the proper marriage certificate management stamp"

I know info2 is refered "Jie(2)Hun(1)Zheng(4)". but I donot understand the infomation 1. does anybody know what it means? I have to submit it ASAP. otherwise it will be denied. but I have to know first what they want. my lawyer does not know what it is. if anyone knows, let me know. I appreciate it
