Id say it won't be a problem. Iv seen graduate courses that would have relevancy to langauge and culture. Usually though you would be focusing in on somthing more specific rather than a broad general view. Somthing like focusing in on Translation, Interpreting, Sociology, Intercultural studies etc. Basically branching off from the broad general cirriculum you once had and focusing and improving in on one or two specific areas. The types of courses offered depends on the college so researching more on the colleges/universities that offer such courses would have to be looked at.
