Compare and contrast the law programs of each school you want to go to, and compare and contrast the countries they reside in. When studying abroad, you have to not only take into account the school you'll be attending, but the surrounding cities as well.
Gather the forms that the college you want to apply to requests for your application process. Each school will have its own application, and may also request additional forms like teacher evaluations, academic recommendations, application fees, and test scores or essays.
Send your application material to the school(s) of your choice, and wait for a response. Once accepted, you will have to set up your own transportation and living situation to attend the school. Many schools will provide on-campus housing.
