Ethiopian embassies abroad charge up to US$63 for visas, and usually require an onward air ticket (or a visa for the next country you’re visiting), a yellow-fever vaccination certificate and proof of sufficient funds. African Ethiopian embassies are less strict.
Visas can be extended to a maximum of three months in Addis Ababa at the Department of Immigration (0111 553899). It takes 24 hours and costs US$20.
The embassy requires US$30 and two photos. It’s usually a same day service.
Visas require US$40 and one passport photo. It takes 24 hours to process. You must call ahead. While Somaliland is proving accessible to intrepid travellers, the recent outbreak of war between Ethiopia and the Islamic militia in Somalia makes Somalia a strict no-go area.
Obtaining a visa can take ages (or simply prove impossible). A letter of introduction from your embassy may help. Visas cost US$61 and require one photo.
