The whole process to my fiancee nine hours which all but about 5 minutes was waiting she said. The only asked her two questions, when did you two first meet and how many times did he come to visit you. They didn't ask for anything else she brought....pictures, chatlogs, I-134,....nothing. After she answered the questions they just told her to wait about three weeks for the visa. She wasn't told congrats, or welcome to the U.S. as others said and also didn't get any 2go paper. It seems all went well and her biggest complaint was it was extremely cold and and the amount waiting she had to do.
