Entry level jobs for FEMA, the red cross or an ESL position in South America?

It is very expensive for Red Cross to send volunteers/staff overseas, and tends not to be a wise use of donor dollars when there are local experts who could do the work better and cheaper, so - sorry to say - but I wouldn't pin hopes on that path. I've worked in disaster management with Red Cross, and what we tell our new volunteers is that international deployments are rare but possible, but only after years of experience with the organization, and generally only for people with very specialized skills: counsellors, doctors/nurses, logisticians, ex-military, ex-police, etc. Basically, we will only send a volunteer (or staff) internationally if there are no locals who are able and qualified to do the job. A few members on my team have deployed from Canada to the US (there's a special relationship between those two RCs that makes this easier) but no one that I know of has deployed further than that.

I have a friend who works for FEMA and I did a ton of work with the phone company in disaster recovery after Katrina. Working in this environment is pretty much the WORST way to travel and see the world. It's absolutely miserable work. It takes a very strong person with lots of real world experience to really be effective. I second the Teaching ESL overseas. Another option is to get a teaching certificate and get a job with Abu Dhabi teaching English. I looked into it and it's incredibly lucrative. As a Jewish person, it turns out I'm not all that keen to go to the Middle East, but man, if I was single, fresh out of school, I would certainly consider it. I saw a House Hunters International where a teacher from Canada was given a stipend that allowed her to get a 3 bedroom apartment in a luxury high rise.

Wait, so Peace Corps isn't an option?

The Peace Corps acceptance rate is less than 25%, and the process takes at least six months, so that's not a viable short term solution. (Peace Corps is an incredible experience; do it if you possibly can!)

Rereading your question - teaching ESL might be the best way to go. I have plenty of friends who have taught ESL in countries where they initially spoke none of the local language, and they got along just fine. You'll learn as you go.

@arcticwoman, any programs in particular you can remember? As for FEMA and red cross responders, there are no specialized positions available? Nothing I can learn along the way? No training?

Nothing I can learn along the way? No training? Well, you could enter into a program to learn these skills, but in general, there's no OJT for recent grads. You could try contacting the FEMA office in your area to find out what they need in http://www.fema.gov/about/career/terms.shtm#Jobs

I do know two people who went from the US to international Red Cross disaster area deployments; they both pursued training and work as EMTs (one got an additional certificate in phlebotomy) and had done significant volunteer work within the US with the Red Cross before even applying. As Ideefixe says, they don't do OJT for recent grads, because they have so many more experienced folks who want to work for them, even in entry-level positions, that they don't need to.

I recommend googling "Teaching Assistants in [spanish-speaking country]." I lived and taught English in France for 8 months last year (and did a LOT of traveling during vacations) through the Teaching Assistant program (I knew very little French at the outset). I'm pretty sure the same program exists in Spanish-speaking countries. It was run through the French Embassy website.
