Not just diversity, most immigrant visas can be obtained through consular processing (CP). You don't need to be in the US for any employment or family based immigrant visa. I am not a lawyer but I imagine only asylees need to actually be in the US for their greencards but they don't need a non-immigrant visa as well.
