Just answering the original posters question by placing all the information in 1 post, including the first link in my post, that I authored years ago.
I guess I should reference who the sources were, but this forum is about sharing information, not about publishing rights

Having already been through the process, I thought I wold provide my take on it.
Outside the required forms and affidavits required, here is a list of everything else you SHOULD TAKE TO THE INTERVIEW:
Evidence - KEEP EVERYTHING

Credit Card receipt for Airline tickets Airline ticket stubs Chat logs (print them out) (She took 3000 pages..hehehe) Phone bills showing showing you called Hotel receipts in VN If you buy her jewelry, keep the receipts receipts for the engagement ceremony and party (dress rental, food, beer, cake, facility or restaraunt,car rental, band or dj, etc) Tax returns / transcripts - take 3 years pictures (you and her/him together / engagement ceremony (make sure they take pictures of all the guests) A list of ALL relatives your fiance has currently living in the US (brothers, sisters, aunts, uncles, cousins. Atleast have the STATE they live in, we provided addresses and phone numbers. IF your fiance happens to be pregnant - take copies of the ultrasounds A timeline of your relationship (this is VERY IMPORTANT - they will give you a BLUE SLIP without one) (send me an IM if you would like a copy) MAKE SURE YOUR EVIDENCE IS SORTED IN CHRONOLOGICAL ORDER.

I am putting together a VIETNAM EMBASSY GUIDE for K1 filers. I have collected much information from VJ, but need some more information.
If anyone has any information they would like to provide such as:
Embassy Diagram Timeline from Packet 3 to Interview
Tips (Interview, Organizing Evidence, Waiting Room)
Hotels close to Embassy
Medical Exam Info
Organizing Evidence for Interview
What to bring & Not to bring
About the many pnadlers outside embassy

Here are two versions of the timeline.
1 is a US version you should take and get notarized.
The other is the VN version that has questions in english and vietnamese that the embassy is likely to ask.
