I found this on the site http://www.info-ghana.com/doing_business.htm that was recommended by another poster I assume as a good site to check for information on repatriation to Ghana:
It reads:

“*Please note, one should not confuse repatriation to the land with investing in the land. Yes, the two go hand in hand, but the governmental agency (Ghana Investment Promotional Center) that was created to facilitate investors do not show any partiality towards humble repatriates, however, they have not made a separate entrance for repatriates, forcing us into the narrow doorway that was created to attract exploiters of the continent rather than sons and daughters of the continent.. It was my very own experience that they rather hold contempt feelings toward repatriates who come without the deep pockets of our foreign counterparts But a learned secret is that when you classify your self as an exporter/importer, you are not required to establish a dollar amount before your application is accepted, otherwise, you are required to show $10,000 minimum investment as indicated”

Well personally I find the Ghanaian Government quite sound in their reasoning if they do not show partiality to those who simply come with their hands swinging and say they wish to repatriate. While many may see African as a Zion paradise where they can go and live out their Rasta colony fantasies of freedom, the truth is that this a country where investment is needed and encouraged, like any other country. If one wanted to migrate to the U.S. or Europe, their governments certainly wants to know what you can offer them by being there and no one takes an issue with that. What Africa needs is strong African sons and daughters who have an honest, contribution to make to the society. To me if people are really serious about contributing to Africa, they should stay where they are and work, build themselves and then go home to establish black-owned business, and invest in the African economy.
