When my wife went in for her interview they grilled her with questions about her trips to the U.S. and were accusing her of immigration fraud. They said that she attempted to immigrate to the U.S without a visa and that she tried multiple times and then she decided afterwards to do it the right way. According to my wife the lady she got to question her was really bad and had her in tears. She tried to trap her with her questions.
They were annoyed that she didn't change her passport to reflect her name change. They asked her to sign her name on a paper she asked how she should sign it and they told her to sign it with married name. Then they proceeded to yell at her because saying she should've signed it with her maiden name because her passport wasn't changed.
She didn't have an original copy of her marriage certificate and they wouldn't process anything because of that. They told her to come back once she had that and there would be no guarantees of her recieving any visa. She had to arrange for a new marriage certificate sent to vancouver where she was staying (at a relatives) and then go back to the consulate. The consulate kept all her paperwork except passport. I decided to take off and fly up there just in case she had to go through the grilling. I'm better at handling pressure then she is. We didn't end up getting the marriage certificate until the day after they expected her back on Friday morning first thing. Nonetheless we got in handed over the passport and marriage certificate. I proceeded to ask when I would recieve it back, he said that they would mail it out as soon as it was processed probably on Monday. I asked if there was any way to get it back the same day because I would've liked to have my wife home for thanksgiving, he told us that he didn't think that was possible then took all the paperwork and told us to have a seat, 30 minutes later we were called back up and they told us that they now have everything they need and to come back at 2:15pm. So we just walked around vancouver for 5 hours and then headed back at 2:15 on the dot. This time they wouldn't let me in to the building and told us that only she was allowed in. 20 minutes later my wife comes out with a visa
I guess not having the correct paperwork for once was a blessing in disguise because if she did have it right who knows if they would have gave it to her. Thankfully my wife spent thanksgiving with me.
If I had to do it all over again I would've been there with my wife for the interview, instead of coming afterwards. I think if you have any doubt that you will be questioned about your relationship. Then you should be there with your spouse.
