Dear Mayeka, I know Africa is not a country but a continent. By free visa I mean, its really easy to get visa approval for African nationals.
I think you should read news papers too rather than only Gooooooooogling... Crime rates in Qatar increased after the arrival of Africans and the culprits caught here in criminal cases are mainly African nationals. I am not against Africans and I also have many Friends from Kenya. But we have to accept the fact and you have to read news paper rather than goooooooogling....
