South African wanting to adopt...

I'm a South African wanting to adopt internationally. We haven't decided on a country yet, only finding out how things work for us at the moment, but we're leaning towards China, Vietnam and Russia. It's very hard to find info online, as all the agencies only mention U.S. requirements. Can anyone help me with info and guide me in the right direction please? Feel free to send me a pm as well. :grouphug:
