I am so excited for you "incanada2016". Police Certificate Clearance in Abuja is very easy. Did mine there. Go to "The Nigerian Police Force (Force Headquarters)
Louis Edet House, Shehu Shagari Way, Abuja - Central Business District, tell them at the gate that you want to do Police clearance, they will ask you to off your phones and drop the phones with them, search you and direct you to the man in charge. Shine ya eye o, they will first tell you to bring 15k-20k but use sweet mouth tell them say na 7k you get, then the bargain fit fall for 8 or 10K. The guy will give you a form to fill, go with your passport photos and you will wait for about 1 to 2 hrs and pick your PCC. Then it is done. They are some ladies there that will want to do bone face for you, no send then, put 100 100 naira change for your hand make you take do "eshe goorn" for them. Wish you all the best, God be with you.
