Well, as you implied, your numbers are pretty good. As you also suggested, your internationalism probably isn't in your favor. That said, several folks from across the pond(s) snag spots every year, so it's in your best interest to apply broadly in the US match... for example, folks I know with scores like yours at my research-based institution applied to between 30-60 places and all matched. With that said, if I were you I'd probably aim for the high side of 100 (of the 150 or so places each year), and your chances are better if you can make ANY personal connection with someone at any one of those departments, and bonus points if you could actually take a month(s) to spend over here rotating. The connection is probably your strongest asset, as many programs are inundated with 240 board scores from local chaps, and so they probably wouldn't make too much effort supposing that you'd fly over for an interview, if you know what I mean...
