Arrival

On arrival at Jomo Kenyatta International Airport Nairobi, you are shown where you will fill the immigration form and pay the $50 If you have not done so in Nigeria, 

Even if you have done so in Nigeria, it is at the airport the Visa sticker would be stamped. on arrival at the airport, with the Ebola issue you can conveniently say you are staying 2 weeks in Kenya as tourist though you are entitled to 90days. Make sure you have your yellow card with you before you see yourself being arranged for return journey to Nigeria!

They will write 2 weeks on your visa, all you have to do is before the expiring date, go and have your visa extension and you get will get the remaining 10 weeks for $23 and also make sure you go to the office of the airline you flew in with to change your return date, l know Ethiopian Airline charges $25.

After your initial 90days has expired you can extend your stay for another 90days with $23

Once your total stay has accumulated to 6 months (180days) the immigration law demands you leave Kenya. Which means you have to go out of Kenya and re-enter, so you will be issued a new Visa, so you can be issued a new 3 months stay after this expires, you extend for another 3 months and at the end of the 6 months you are expected to exit Kenya and re-enter to start the process all over again.

l know Nigerians here do not exit to re-enter but please do not ask me how they go about it until you enter Kenya and use your own mouth and ask them, lol! l know a Nigerian who imports cars from Japan to Kenya and has lived in Nairobi for over 16yrs and married to a Kenyan woman, he is still extending his Visa every 3 months!

If you have the resident permit (for workers) or the Kenyan Student Pass issued to foreign students who qualify you have no business with visa extensions nor the exit and re-enter policy.
