The Nigerian Immigration Officials are bringing shame to Nigerians home and abroad for collecting bribes and creating new scams everytime Nigerian or foreign passengers come in and out of Nigeria.
These officials collect as follows:

1. Money on food items you want to travel with for your own consumption.
2. Demand money from first time Nigerian travellers.
3. Scam foreigners of their money by accusing them of overstaying
their visas.
4. Persons who refuses to bribe them are delayed so they can miss their flight.
5. Other Airport and Airline officials also demand for money as if they expect you to empty all the Naira in your pockets for them.
6. The cart for pushing the bags and boxes should be free and not paid for.
