I would start out saying you are just visiting, then if they ask visiting who say family, then if he continues to ask yes I would recommend say wife. The reason why I would use this approach is you are not lying and you are also not giving way too much info out. The officer may just let you go once you say visiting so it is worth being vague. In my case the guy did press until I said wife. He didn't seem to care though that I was visiting. He did ask who is moving where I said I'm going to move to Canada and have outbound paperwork. He asked where I work I said in the states. I had a few of my last checks in case but I never had to show any proof it was all verbal and quick. I didn't even go to secondary. I flew porter air and there were only 3 officers who seemed to be all decent. I think on his screen he knows we have applied, but I am not sure as he didn't tell me what was on his screen. Perhaps he was testing me and already knew I applied already and since I told him he then figured i wasn't hiding anything. Anyways, never lie but you can be vague. Good luck! I was definitely nervous but it was one of the smoothest crossings I've had. Bring any proof of ties just in case
