I don't really know much about the subject. But I have been telling my D to get herself a license to teach english. This really isn't what "she's always dreamed of", but she does some tutoring on the side from school and also works as a traslator/interpreter. So, although perhaps she doesn't think of this as a career to pursuit, it could land her nice jobs (lately I see many vacancies por english/foreign language teachers). She is about to finish her UG degree (not in education).
What options could she have for teaching ESL or a foreign language to english speakers?
