I have hundreds of Nigerian born friends myself. Some of them are in the US and some are in Nigeria. I hope to go there some day and see the country.
MOST folks go for money though. They are hired for oil exploration, drilling, refinery engineering or refinery construcion and make good money.
I only have one...he wrote me an e-mail. Seriously though, I will never step foot on Africa. More power to you for going. Islam will get worse and worse.
