The fist thing to look at is the most obvious but often overlooked. Find out if the program is taught from an English centered standpoint even though it is in another country. This is not a problem for places like Australia or Britain, but if you want to go to school in France you will be hard pressed to find a program in English. Even if you have a strong second language it is going to be difficult to do a several year long course of study in a language that is not your primary one. This can be part of the charm, so then find one that has these limitations, but note that this is not the most effective way to do this if you are going to primarily do film work in the U.S. This is what is notable about schools like the Film and TV School of the Academy of Performing Arts in Prague, which will do their programs in English for a truly international approach.
