Also, look at the department’s focus: is it literature, and if so what period? Is it culture and if so how is it incorporated into the classes?
For instance, Dickinson (a LAC that is very “international-minded”) focuses on culture; it has study abroad centers in many countries. Gettysburg (a similarly-ranked LAC) requires several classes in Linguistics and has a stronger traditional language/literature focus. At both, intro classes will be limited to 15-16 students and upper level classes will be seminars with 8-10.
For study abroad: can you spend a year there? Can you take classes in a local university? Are all your classes related to the Spanish major or can you take gen eds and classes that count for other majors (business, science…)? Does your financial aid cover everything beside the plane ticket?
Double majoring: is there a way for you to complement your major with something else, such as business? Spanish+premed is a great choice, how easy is it to do? If interested in a PHD, what’s the support for undergraduate research, undergraduate conferences, publishing papers?
