Unfortunately I don't know anything more about the intelligence opportunities at MIIS, she had only heard the name of the school and it's reputation for being good.
I know what you mean about MIIS being expencive, but I think for me it is the right choice for several reasons. The location is nice, there are students from all over the world, many internship opportunities and I like being able to combine development studies with Spanish (as I did in my undergrad). Fortunately the Norwegian government has a good loan/scholarship offer for doing a master's abroad, and MIIS also offered me a scholarship, so although I will end up with a big load, to me it is worth it.
So Middlebury has a very good reputation? Equivalent to Ivy League? Can you explain? It sounds great, but being from Norway I have never heard of Middlebury (I have heard of Ivy League!), but of course the status of the school is quite important in finding a job!
Good luck with making a choice! When do you have to decide?
