Citizenship by naturalisation

Section 27(2)(g) · 1999 Constitution (2004 edition)

What Constitution says

(g) he has, immediately preceding the date of his application, either- (i) resided in Nigeria for a continuous period of fifteen years; or (ii) resided in Nigeria continuously for a period of twelve months, and during the period of twenty years immediately preceding that period of twelve months has resided in Nigeria for periods amounting in the aggregate to not less than fifteen years.

This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
