I spent a month in Puerto Escondido Oaxaca Mexico. Oaxaca is the
poorest state in Mexico. You can check out my trip blog

and my experiences.

CFHI Application Fee: $65

Program Fee 2007/2008: $1935 + airfare but each site is different cost.
CFHI has 12 rotation sites around the world.

I recieved a grant from my school because I am spanish speaking so part
of my trip was paid for.

You fill out you application for whichever rotation you want and
request a date and CFHI takes it from there. They are very organized
and prepare you well for spending time abroad. The webiste is very
helpful and has all the information about the rotations.
