Dual citizenship

Section 28(1) · 1999 Constitution (2004 edition)

What Constitution says

(1) Subject to the other provisions of this section, a person shall forfeit forthwith his Nigerian citizenship if, not being a citizen of Nigeria by birth, he acquires or retains the citizenship or nationality of a country, other than Nigeria, of which he is not a citizen by birth.

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