Becoming a exchange student in Spain..?

There are official exchange programs where a lot of the hles are taken care of for you. Your school should have information on exchanges they participate in. I know the agencies that handle these in the U.S., but I don't know if they do European exchanges as well. If your school doesn't have the information, Google "language schools Spain" or "exchange programs Spain". It should be quite easy since you are all EU residents- you don't even really need a student visa.
