When file I 130 and I 485 concurrently, shall I put a copy of all the documents for I 130 into I 485 package and vice versa, or it\'s not necessary?
I currently have a copy ( 副本of my marriage license, the one that the witnesses and administraor signed on the day of wedding.) and the other one was sent to be filed with the county. Is this copy considered as Proof of Marriage? or I need to get something back from the county? Does either one need to be notarized in order to act as a proof?

Thanks a lot!
