In an interesting new twist, it suddenly isn't clear if the expulsion is only for the North (i.e. Darfur, Khartoum, Kordofan and the Eastern States) or if it is for all of Sudan including Southern Sudan. Meaning all those organisations could ALSO be kicked out down here, but just not know it yet.
We are, you see, technically one country even though de facto we are two. For example, I don't have a visa from Khartoum, mine is from Juba (hence it is a funny little rubber stamp instead of a fancy sticker) and I am not registered with a work permit from the north (good thing since I was firmly encouraged to leave last time and I doubt I'd be let back). Organizations generally run two country offices, one in Khartoum and one in Juba and the programs are rarely linked (I couldn't tell you the name of a single staff who works for my organization in the North nor could I tell you what programs they run).
All this, however, is down to practice. If they suddenly start practicing the letter of the law, which Bashir (the now indicted president of all Sudan) would be completely within his rights to tell Salva Kir (the President of the SPLA/M, leader of Southern Sudan and First Vice President of all Sudan) to do, then trouble will come a'nockin. And I'll be chilin' in Nairobi for three months, minimum, I'm sure.
