I'm not 100% sure, but your 4th year you have some rotations that you have to do at VCOM approved sites. You also have 4-5 medical/surgical electives/selectives that you can do at any site as long as you get previous approval. The current advice is to use these electives to visit places you are interested in for residency to see if you like the hospital, people, etc, and so that the program directors and such can meet you. So I'm pretty sure you are able to go anywhere you like. I would look at the website under 3rd and 4th year tab for more information.
