Ireland dual citizenship rules

Who Can Claim Irish Citizenship

Ireland allows dual citizenship, which means you can hold Irish citizenship alongside another country's citizenship. This makes it easier for people with Irish heritage to connect with their roots.

You may be eligible for Irish citizenship if:

• You were born in Ireland
• One or both of your parents were Irish citizens
• One or both of your grandparents were Irish citizens
• You were adopted by an Irish citizen
• You've lived in Ireland for a required period and meet residency conditions

Irish Citizenship by Descent

Many people qualify through their family tree. If your parent, grandparent, or even great-grandparent was an Irish citizen, you might be eligible.

Important points about descent:

• Your ancestor must have been an Irish citizen at the time of your parent's birth (if claiming through a grandparent)
• The line of descent must be unbroken — there's a specific generation where the chain can break
• You'll need official birth, marriage, and death certificates
• Foreign adoption may affect eligibility in certain cases

The Application Process

To apply for Irish citizenship by descent, you'll typically need to:

• Gather original birth, marriage, and death certificates for everyone in your ancestry line
• Complete the official application form
• Provide proof of identity
• Pay an application fee
• Wait for processing — this can take several months to over a year

The exact process and required documents depend on your specific circumstances. Some people can apply online, while others must apply in person or by post.

What You'll Need to Prepare

Before starting, collect:

• Original or certified copies of birth certificates
• Marriage certificates
• Death certificates
• Divorce decrees (if applicable)
• Adoption papers (if applicable)
• Your current passport
• Proof of residence

Many of these documents need to be official certificates with raised seals, not photocopies.
