As stated above, there are many, many possibilities with French or any other foreign language. And given the increasing globalization of our world, international relations would be well worth considering as a major and career. I would suggest that you try and narrow things down to what you like to do and/or are good at besides French - perhaps that way you can select a few major and career options, and then incorporate French with those. Private sector, government, and NGO paths are open to those with language skills. You may even want to consider volunteering at some point, perhaps doing some translating, mentoring/tutoring of Francophone refugees or immigrants, etc. In doing so, you'll gain actual experience that you can use to market yourself. Whatever you decide, go for it! I'm a fellow Francophone and have used my French in many, rewarding ways. Enjoy and bonne chance!
