A visit to the different embassies in Lagos and Abuja will give you a fair idea of the number of Nigerians who want to jet out of the country.
Getting the visa for some is like a lifeline. It is either they get it or nothing else. Rejection for them is unacceptable.
1. Forget about all the stories of rejection you have heard
There are lots of stories about the mean consular officers at the embassies and their knack for rejecting visa applications. Do not allow these stories to get to you. Have a positive mental attitude and you will be surprised that if you genuinely respond to interview questions, you will get the visa.
2. Arrive very early
There is no African time in this case. As early as 7 am some embassies have kicked off their screening. If you are late, your chances of even being allowed into the premises are very slim let alone being interviewed.
