I am a US resident.

I was wondering, is it possible to open up a Full Tilt Poker account using a PO Box? I wanted to open up an account under a business name and have a seperate PO Box just for this account.

Does anyone forsee any complications, if for example, I want to cash out and request a check? Would this cause any problems with cashout?

I don't think it would cause any problems if I used Epassporte to send/recv funds.
