Have you ever applied to overseas volunteers program?

I have respected people who serve the community. I have done some volunteer works at nursing homes and orphanages and I always feel worth doing it. Yesterday, I watched a program about oversea volunteer working of KOICA(a volunteer organization). They have done voluntary work for people who live in a bad environment in Africa and South America, Asia. Including medical and education service, construction, they have offered them a diverse of services. I was quite expressed that they were trying to communicate with them and join them sincerely.
