I have a Master's in Applied Linguistics, and I teach English to International Students. I've known people with similar education who have worked as communications and marketing professionals, language test developers, text-book publishing consultants or writers, language test raters, academic tutors in writing centers, copy editors, and more. One of my major professors has been studying the pragmatics of online reviews on travel websites. The field opens up many possibilities. You become an expert on how languages work, which is pretty applicable in many contexts!
