In other words, when a USC marries a VN National after obtaining a K-1 Visa would the VN Government recognize the marriage. I think they do but I'm having trouble locating the proof on the net.
In you case, must do it before you wife give brith in Vietnam
1. Take your marriage's license to your County, ask them certify the signature on license
2. Then take it to your Capital's State, ask the Secertary's State to certify the County's Signature.
3. Then send it to Vietnam Embassy in DC to verify, and translate to Vietnamese that this document is true.
Make sure you call the Embassy ask for the fee.
When everything is done, your wife take those papers to Vietnam and she will be fine with local government office.
Hope it helps.
