I want to drop a line to my #1 residency choice and let them know I'd like to go there. Is it too early to do this and should I wait until closer to when the rank order list is due? I'm also debating whether I tell them they area "a top choice" or "my top choice". Also, just what can/can't I tell them. I don't think I'd be violating any NRMP matching rules by telling them this.
