As for visas in general, have a crack at obtaining a Schengen one! It's quite a demeaning and expensive route if you want to come up to Europe from South Africa, for example. As for the USA'ers being a trifle ticklish about entry visas to their country, who can blame them with, at least by all accounts, all of the English wanting to leave their own wonderful land because they themselves are being pushed out by the eastern hordes, a by product of their own mismanaged policies?
