mali visa at border
there was information of possibility to get Mali visa on the border somewhere there. I just returned from Mali, and, arriving from Mauri at Nera border post, we didnt had a visa. We were told, yes, its possible to get visa at the border, but they didnt had the visas as such to issue! But without problems, and for a small fee we got our entry stamp, and were allowed to proceed, and from now on nobody seemed to care. But, once in Bamako, we headed to 'securite', where without probs we got our visas for 15000 CFA (20 EUR), 2 photos required, 24 hours.
Hope it helps.
