According to Tourism Update, the Kenyan government has introduced a new e-visa service for UK and Irish travellers, which comes into effect today (2 July).
There is a two-month transition position, until the end of August, where visitors can still purchase their visa in person at the Kenya High Commission in London, at the Kenyan Embassy in Dublin, or on arrival at Jomo Kenyatta International Airport in Nairobi.
The e-visa will be compulsory from 1 September, and travellers are advised to register for their e-visa application in advance. Approval for the e-visa can take up to seven days.
