Non-South African Citizen applying or BoAML's South African Off Cycle Internship. Any chance?

Hi!
I am Oscar, a Chinese student studying in Hong Kong. I am wondering usually when one applying for a location where he does not holds a citizenship, does he have possibility to be offered a place? and how much probability?

And I suppose that situation may be different when non-citizen applying intern in US, Europe and South African. I mean, yes, it is very competitive in US markets where famous school students, native speaker of English are anywhere. But for Africa, will the bank only recruit the local student?

Thank you all for your advise and comments.
