I have used Give Foundation to donate to Amar Seva Sangam, which is a non-profit based in Tamil Nadu. They do not have a front-end in the U.S to raise funds and Give Foundation allows me to donate to them, and receive tax deduction in the U.S. They essential serve as a pass-through. I had a very good experience very time. My donation reached the end-organization. They also sent me feedback obtained directly from the organization that indicated how the funds were used.
