I was at NCAT early this year to make enquiries and i was shocked to find out taht the cost is higher than what you can get in SA or USA especially considering the fact that alot of your time will be wasted.I m not really sure but the amount quoted was between 5-7M NAIRA for the spl.
I think that is one of the reasons that discourages young Nigerians.
I was lucky to have gotten the US visa recently without much stress and maybe others dont get because they dont meet the criteria, TSA ,etc.
