Ireland allows dual citizenship, meaning you can become an Irish citizen while keeping your original nationality in most cases. This makes Irish citizenship highly attractive for people with Irish ancestry, foreign residents, and UK citizens after Brexit.
Today, over 70 million people worldwide claim Irish ancestry, despite Ireland having a population of just over 5 million. This explains why Irish citizenship by descent is one of the most searched nationality topics globally.
Understanding Ireland’s citizenship rules helps you plan for travel, work, and long-term residency rights.
Ireland is an independent country with clear legal rules for citizenship. You can become an Irish citizen through:
Birth
Descent
Naturalisation
Before 1 January 2005
Anyone born in Ireland was automatically an Irish citizen
After 1 January 2005
Birth alone is not enough for citizenship
Citizenship depends on parents’ citizenship or residency status
After a constitutional change, birth in Ireland is no longer an automatic right to citizenship
You may qualify if:
A parent was born in Ireland
A grandparent was born in Ireland and you register in the Foreign Births Register
Your parent is already an Irish citizen through descent or naturalisation
Foreign residents can apply to become Irish citizens through naturalisation if they:
Live legally in Ireland for a required period
Meet residency and good character requirements
Complete the citizenship application process
Irish citizens are also EU citizens, which means they can:
Live in any EU country
Work in EU member states
Study across Europe
Travel with an Irish passport
Irish citizenship law is based on:
Constitution of Ireland (1937)

Before the 1937 Constitution, Irish citizenship was based on the Irish Free State Constitution.
