Be real careful, though. If you say you're staying for a week and then overstay that, I have no idea what would happen. When I said I was staying for ~5 months I got grilled but I had all my documents in order and he let me in for the full 6 months. I had our marriage certificate, a letter of invitation from my wife, photos of us together with stuff in the background that proved timeline, my FBI cert, passport with previous visas for long stays, bank statement, RETURN TICKET (super important), and I'm pretty sure some other stuff too. There are certain things they can turn you down for, and if you prove all those are non-issues it's much harder for them to say no. It's called "Dual Intent" and I'd look it up if I were you. They normally have to give you a specific reason on that list and give you a letter about it. If they pull it off it'll also make moving to Canada MUCH harder. Best to have all those bases covered so they grudgingly let you in. At least, that's been my strategy. Bury them in paperwork and documents shutting off every normal avenue they have for denying me.
