Ryan1234,
I'm not sure. I'm new at this like you. Although, I'm pretty sure during training they frown on bring your family or wife to training. If you go on the CBP websites, I believe it address that very question.

The paper work is a hassle. I'm trying to think back 10 years of my living history. As a poor flight instructor and airline pilot (at the time), a crash pad was home. Address and dates....? Got me... I spent a whole day writing an outline on paper first, before doing the on line questions.
