  • The applicant's mother born in a territory that was (or became) a former British Protectorate, Protected State, Mandated or Trust Territory or Colony; AND
  • The applicant's maternal grandfather was born in Ireland before 31 March 1922.

A further requirement is that the applicant must not have suffered from the Automatic Loss of citizenship that was enacted upon the independence of their mother's country of birth.

WhatPassport.com is a specialist UK Nationality and British Citizenship site offering an online search and assessment. Claims to hold a British Passport can be complex and the site offers a quick, simple search to give you the answers. While many people qualify for the UK Ancestry Visa based on holding a Commonwealth passport with a UK born grandmother or grandfather, we have found that if you have a grandparent born in the UK, or if your mother is British or your father is British, then there are several scenarios where you can claim British Nationality and the right to hold a British Passport. This stems from Britain’s collection of British Colonies, British Protectorates and British Protected States in the middle of last century and the Nationality rules concerning what are now the countries of the Commonwealth.
