When I visited Emory, one of my questions was their study abroad opportunities. They seemed very vague, and basically said that you could come up with your own summer plan and they would work with you on it. It didn't sound very organized, like other schools I visited.
ND may have the only year long program, but many schools offer either a semester or an organized summer (usually after 1L) abroad. Most of the schools I researched had more than one program.
