In Nigeria, the categories of citizens that cannot be declared as non-citizens under any circumstance are those who are citizens by birth and parentage. This means that individuals who acquire Nigerian citizenship either by being born in Nigeria or through their Nigerian parents cannot be stripped of their citizenship status.

Citizenship by birth is granted to individuals born in Nigeria, regardless of the nationality or citizenship status of their parents. This principle is enshrined in the Nigerian Constitution, which recognizes jus soli (right of the soil) as a basis for acquiring citizenship.

On the other hand, citizenship by parentage refers to individuals who derive their Nigerian citizenship from their parents. This can include situations where one or both parents are Nigerian citizens, thereby passing on their citizenship to their children.

Both birthright citizenship and citizenship by descent are fundamental aspects of Nigerian nationality law and are protected to ensure that certain categories of citizens cannot be declared as non-citizens under any circumstances.

In other words, these two categories of citizenship, by birth and parentage, are fundamental and irrevocable under Nigerian law. Regardless of any subsequent actions such as naturalization or registration, individuals who are citizens by birth or parentage cannot be declared non-citizens.
