I am gonna make you happy
( I am assuming you plan to Land in Niamey )
You CAN get the Visa for Niger on Arrival !!!!. No wait , no queues . Just 15.000 FCA (30 Euro / 20 quid )
and ITs not a exception . At least 10-20% of the passangers don't have the visa , and hence expect to get it on the Airport
Procedure is as follows :
1 Upon Landing , get to the inmigration Queue. (preferable at the end of the queue)
2 State that you don't have a Visa /. Ask for a Visa
3 The clerk in the inmigration booth will take your Passport , and give you some kind of receipt for it
4 This receipt allows you to go throught Inmigration and collect your baggage
5 With your baggage , Go to the Police station in the very same Airport (Its actually inside the Terminal)
6 Wait your turn , enter the office , and write down your name , address , etc.. etc.. , pay 15000 CFA (they take Euros or CFAs ,. they DONT take anything else )
7 stay outside again .
8 in 5 minutes , a good-looking lady calls your name , and gives you the Passport with the VISA . !!!! Enjoy the taxi-driver marabunta.
If the flight happens to arrive in the night , the procedure is a bit different . After writing down your name , details , etc.. (point "6") you are asked to go to your hotel /etc.. . Don't worry , the receipt you are given is as good as a passport to book a hotel , etc.
Then , next day grab a cabby to "DGT" (Direction Generale Territoriele -or something like that -) ... and there , you trade your receipt for your Passport (with visa on it )
Any need for info about Niamey .. just ask .
Thanks a lot
