Even the Peace Corps is probably not an option. They expect degrees or years of experience in a field. I'm sure you have to be 21, and they are trying to get older people, not younger people, to volunteer.

I'm with gopher.

People have this romantic idea of going off to live the simple life in some developing country. The simple life is nice as long as it is an option, as long as you can decide to pack it in and go home. For most people, the simple life means struggling to house, feed, and clothe their children. It can mean working dawn to dusk, hard, just to survive.

Sometimes what people mean by leading a simple life includes running water that is drinkable, flush toilets, electricity, air-conditioning, and only having basic cable. I'm not saying you are like that, but it isn't unusual.

I recently met someone who did a volunteer stint in a small village in Africa. Whoever she volunteered with didn't put her in a reasonably comfortable place, but in a village where the nearest water (not clean, safe, water, just water) was over a mile away and had to be hauled by hand in buckets.

In addition, you would have to be self-supporting. With no skills to offer, you are going to be competing with people who will work for a lot less than you will be able to live on.

And again, you have to find a country that will let you move in and stay, when you aren't offering anything they don't already have.

If you have some money saved up, you could go traveling and volunteer as you go, serving as a native speaker in schools, for instance, so students can practice their English.

If you might want a career working for NGOs, you might contact them and ask what sort of skills they are looking for now and expect to need in the future, and consider that when choosing a major. Just don't make the mistake of thinking that knowing a foreign language makes you unique. In the rest of the world, second and even third (and in the Netherlands, fourth) languages are just adjuncts to your real specialty.
