hello, I am a canadian who will be soon flying to california to drive with my wife back to canada. I have the marrage certificate, the recipt from the PR application and a letter from my employer to show I can support us, so they will let us in giveing my wife a visitor status. My question is do I need to buy a two way ticket or can I just be up front at customs on the way down, and just show them the paperwork I will show them on the way back in, Thanks
