Do some research and find legal immigration firms that are serious and help African either migrate or find work abroad. By serious I mean that they must have a meaninful operational budget. The one firm I think about is http://www.andela.com. They are not immigration firms but they allow african developers work for US companies.
I am looking for anything that allows Africans to go abroad or to work companies abroad.
