I'm a Burundian who lives in South Africa and holds a Rwandan refugee passport. Can I use this passport to travel to Kenya? I didn't use it when I came here to South Africa.
It appears that you may be able to use this document to enter Kenya if you are granted a visa, for which the fee is $50 (source: Biometric passport gives Burundian refugees a second chance):
The document gives access in all the countries of the world except that of origin of the refugee. However, Kenya and Tanzania do not readily accept holders of this document and a $50 entry visa fee is charged for users. Rwanda hosts more than 172,000 refugees, more than 53 per cent of whom are Burundian.
Unfortunately, I have no idea whether "Kenya and Tanzania do not readily accept holders of this document" refers only to the $50 visa (which is in contrast to the privilege of Rwandan citizens to enter without a visa) or if it implies that additional difficulties might be in store.
