It is essential that the person concerned should have held Commonwealth citizenship or British subject status on 31 December 1982 and has not voluntarily or involuntarily ceased to be a Commonwealth citizen (even temporarily) after that date. For this reason, citizens of Pakistan and South Africa are generally not entitled to the right of abode in the UK as these countries were not Commonwealth members on 1 January 1983, unless they have citizenship in another Commonwealth country. However, citizens of Fiji (left the Commonwealth in 1987, rejoined in 1997) and Zimbabwe (left in 2003) are still continuously considered to be Commonwealth citizens for nationality purposes even after the two countries' withdrawal the Commonwealth because the UK has not amended Schedule 3 to the British Nationality Act 1981 to that effect. Since 1983, the only two countries that withdrew their Commonwealth membership and were subsequently removed from Schedule 3 are The Gambia (removed in 2013, re-added in 2018 but has no effect reviving the right of abode) and Maldives (removed in 2017), and, consequently, their citizens would have lost their right of abode on the day these countries were removed from Schedule 3 unless also holding British citizenship or citizenship of another country listed in Schedule 3 (which now includes South Africa and Pakistan).
