When applying to an ACA academic year program that requires a student visa, make sure you accommodate the time for the visa process into your summer plans. The ACA office will notify you and provide instructions/documents for the student visa. Some visas can take as long as 2 months (e.g. Spain). Apply as early as possible!
Note: Before applying for the academic year programs in Argentina or Spain, students must have completed either 2 years of Spanish language in high school or 1 year of Spanish in college. ALL other programs (first quarter of academic year + summer) accept students who are total beginners in the target language. There is NO language pre-requisite for the summer program in Spain.
