A 30 day visa can now be applied for on landing at Freetown International Airport for £25 or $40. This is an interesting development and will no doubt be convenient from countries where there is no Sierra Leone diplomatic representation. I wonder why its cheaper than applying through our foreign missions though.. This is being dicsussed here
Edit to add: This is still subject to approval from govt. So don’t be heading out to Sierra Leone without a visa just yet!
