United Kingdom - flag United Kingdom - Passport & Nationality - Irish Citizenship by Double Descent (GP born in Ireland)

If you were born outside Ireland to a mother or father who were themselves born outside Ireland and if any of your grandparents was born in Ireland, then you are entitled to register as an Irish citizen. However before you can claim Irish citizenship, you must have your birth registered in the Irish Foreign Births Register.

The Irish citizenship of successive generations may be maintained by each generation ensuring their registration in the Foreign Births Register before the birth of the next generation. Children born to that generation before its date of entry in the Register are not entitled to citizenship. Unless at least one parent or grandparent was an Irish citizen at the time of your birth, you cannot claim Irish citizenship on the basis of extended previous ancestry or wider family ties such as the Irish citizenship of cousins aunts, uncles etc.

Irish nationality can ONLY pass down by descent if the birth is legitimate.

Finally, an Irish passport will allow you to live and work in the UK. This right pre-dates the UK's entry into the EU, and is therefore not affected by the UK's recent exit from the UK.


Ask Philip Gamble whether you (or your children) have a claim to British nationality.

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.
