You got my attention since you mention Burma. I read through your post and reply. So you and your wife made marriage ceremony just to satisfied your spouse's parents, but you are planning to make Utah online marriage. In my opinion, online marriage probably be acceptance with the US Embassies in other countries, but it is a bad idea for embassy in Burma since the final decision is solely base on embassy. In Myanmar, the marriage can happen in court, church, temple or mosque. All is recognized as legal. But in I-130 case, you have to have civil/authority registered number and the one who solemnized must be licensed (even though mine was not licensed, they accepted it. I think it was because of my location of the marriage took place.). There are a lot of places where you can have registered marriage certificate such as Baptist Church, Assembly of God church etc. Find the pastor who embassy recognized as licensed, there are a bout 4 of them in Yangon as I heard. The certificate will be in Burmese, but it's ok you can have notarized translations which most of the people do. You need your spouse copy of NRC along with translation, police certificate with translation, birth certificate with translation (might need letter from hospital about no record of birth by the time of visa interview since embassy don't trust most birth certificate), marriage certificate with translation, copy passport.
You and your wife should go back to Myanmar and make marriage. I don't know if you can apply I-130 from out side of US or not but I wouldn't do it out side of the US. Best of luck!
