Where can I volunteer or work abroad and learn spanish?

I’m going to be graduating in December, hopefully, and I want to volunteer or work abroad and learn spanish while doing it. I understand a lot of spanish, but can hardly speak it. I was thinking of the peace corps, but that is a very long commitment. I want to go for about a year [...]

If you were study abroad to learn to speak Spanish, where would you go?

It’s a dream of mine to learn Spanish in a Spanish speaking country! I don’t want to hear any info on learning to speak Spanish here, I want to go out of country for about 6 months to a year if it takes that long.
Where would you go?
