please i need info,i cant seem to find anything on the internet. maybe wen i return,i will post my experience for others to benefit.

That's a bit confusing. If you travel to the U.K with your America passport, all good, but if you use your Nigerian Passport to leave the U.K, how will the U.K immigration know you left? there will be nothing on their system to indicate the "American" that came visa free actually left they will only have a departure for a Nigerian. I guess you need to find out more from the experts.

Pretty simple:
US - UK - US passport
UK - NIG On UK side when leaving use US passport, upon arriving in Nigeria use Nigerian Passport. When leaving Nigeria use Nigerian and US passport.
