Well canadian cars are pretty easy and in retrospect very inexpensive to import. In order to get a right hand drive ITR imported into the us that's not a chop, it'll cost you very close to ten grand . There is a whole slew of different proceedures and hassles you need to go through, and for the most part, most of it you can't do yourself, and would need to pay a company like Motorwreck or evolution imports, who has experience in it.
Don't get me wrong, it's possible, but do you really want to pay close to $30K for a 2 year old ITR???
Try and find one that's alreay here, it'll be a lot cheaper, and a hell of a lot less hassle.
