If you are interested in volunteering
There are many volunteer organisations offering similar opportunities, but I went with International Volunteer HQ, who are based in New Zealand and offer programs in developing countries in Africa, Asia and Central and South America. Volunteers can work as teachers, in orphanages, or in medical placements.
