Hi and welcome to the forum.

I take it you're currently in the US. Don't mean to be a nag, but as far as finding some sort of volunteer or other organization that could get you overseas, you may well find you'll have more opportunities with a college degree, or at least with some specific job training under your belt.

However, have you looked into something like the Peace Corps? Or any of the many aid agencies (Red Cross, Doctors without Borders, etc.) where you might be able to get some training and where your language would certainly come in handy. If nothing else, see what skills and background these agencies are looking for and that might give you some further ideas.

I started out with a university degree in German and Theater, but when I decided I didn't really want to do the waiting tables until I got my "big break" routine, I decided to get an MBA. After 15 years of accounting and finance, imagine my surprise when I found that a US-trained accountant with two foreign languages could actually find a job in Europe! The rest, as they say, is history. <g>
Cheers,
Bev
