Personally, I would not go for a master's in Speech Pathology unless it were a field I was strongly interested in. Such a specific degree limits one's career options, I imagine. Not a problem for people who really want to work in the field, of course, but perhaps not ideal for someone who just wants to do something other than teaching. Since your goal is to work internationally, I would say either business school or law school would be good options. Law school is the better choice, I think, given that once you get your degree and pass the bar, you'll have a specific skill that few non-US nationals will have. That will make it easier to get a job and a work visa just about anywhere. My understanding is that American lawyers working abroad are seldom on the bar in the country they work; they are legal "consultants", officially, and focus solely on the aspects of cases pertaining to American law. I recommend narrowing your focus beyond "something other than teaching". What interests you about business? Do you want to work in management, logistics, marketing, finance? It may be beneficial to hone in on a field, and figure out the educational requirements from there.
