Since the UK’s departure from the European Union, a record surge in Irish passport applications has been seen, with more than 20,000 applications lodged every month since January 2023. This rising trend indicates that the UK is on track to set a new annual record for Irish passport requests. Data from the Department of Foreign Affairs reveals that nearly 82,000 applications have already been submitted from the UK this year, in addition to 87,500 from Northern Ireland. This combined total has already surpassed pre-Brexit figures, more than doubling the typical annual demand for Irish passports.

For UK citizens, the surge is driven by a variety of factors, particularly Brexit-related travel and residency restrictions, as well as the growing desire to ensure future access to EU benefits, such as freedom of movement for family members and children.

Why the Surge?

A significant factor behind the surge is the desire of UK citizens to secure EU citizenship through their Irish ancestry. Many individuals are seeking a backdoor route to EU membership, especially parents who wish to ensure that their children will have access to live, work, and study in the EU in the future without facing the restrictions imposed on UK nationals after Brexit.

The Irish passport has long been regarded as one of the most powerful in the world, consistently ranking among the top countries in the Henley Passport Index. With visa-free access to 192 countries, the Irish passport provides dual nationality, which is highly sought after by those looking for greater international mobility. This has contributed to an increase in applications, with many turning to the Foreign Births Register to prove their Irish ancestry.

Growing Trend and Economic Factors

While Brexit remains the central cause, other factors are also at play. Economic pressures in the UK, such as high living costs and changing property regulations, are motivating people to explore alternative citizenship options. For example, Spain recently introduced a 100% super tax on non-EU property buyers and ended its golden visa programme, which had previously attracted wealthy non-EU investors. Similarly, Ireland has made moves to attract high-net-worth individuals, which may further increase interest in Irish passports.

Furthermore, as a result of these economic shifts, many individuals from the UK are viewing Irish nationality not just as a travel or lifestyle advantage, but as a valuable asset for future generations. The ability to pass Irish citizenship down the line, particularly to children, is a major driving force behind the surge.

The Role of the Foreign Births Register

Many of the Irish passport applications have come through the Foreign Births Register, where individuals can prove descent from Irish parents or grandparents. This process allows people with Irish heritage to gain Irish citizenship, even if they were born outside of Ireland.

According to official data, the Foreign Births Register saw a 15% rise in applications in 2022, with more than 23,000 applications processed—the highest level since digital records began in 2013. It is estimated that approximately six million people in the UK have at least one Irish grandparent, making this route a particularly viable option for many seeking to regain or acquire Irish nationality.

The Impact of Brexit on British Citizens

Brexit has created uncertainty regarding travel and residency rights within the EU for UK citizens. Prior to Brexit, UK nationals enjoyed the freedom of movement that allowed them to travel and settle anywhere in the EU. However, with the UK’s exit from the EU, this freedom was revoked, prompting many to seek alternative solutions to ensure they can continue accessing EU benefits.

By securing an Irish passport, UK citizens are not only gaining the ability to live, work, and study in EU countries, but they are also circumventing restrictions on things like healthcare, pensions, and education that now apply to UK citizens post-Brexit.

A Look at the Numbers

  • 82,000 applications have been lodged from the UK this year alone, alongside 87,500 from Northern Ireland.
  • The surge in applications is more than double the pre-Brexit annual volume, with demand now consistently exceeding 20,000 per month.
  • The Foreign Births Register saw a 15% rise in applications, with over 23,000 processed in 2022 alone.
  • An estimated six million people in the UK have an Irish grandparent, making them eligible for an Irish passport.

Key Economic Impacts

The rise in passport applications from UK citizens is having a significant impact on both businesses and the tourism sector. As more people acquire Irish passports, cross-border travel between the UK and Ireland is expected to become more fluid, boosting tourism and trade between the two nations.

Moreover, the broader EU market benefits from this increased connectivity, with more UK nationals able to access jobs, healthcare, and educational opportunities within the EU. This is a key benefit not only for individuals seeking more freedom but also for the broader EU economy.

For those working in business and finance, an Irish passport also opens up access to the EU’s single market, providing greater opportunities for individuals and companies seeking to operate across the European Union.

What Does This Mean for Tourists?

For tourists, securing an Irish passport can be an important step toward making travel easier and more accessible. Irish passport holders enjoy visa-free access to nearly 200 countries worldwide, making it a valuable asset for international travel. Additionally, those with Irish ancestry can take advantage of this by securing their Irish citizenship now before their children are born, ensuring future generations have greater mobility and fewer travel restrictions.

Steps to Apply for an Irish Passport

  1. Confirm Eligibility: Check if you qualify for an Irish passport through ancestry via the Foreign Births Register.
  2. Submit Application: Gather your documentation and apply for citizenship through the Department of Foreign Affairs or local consulates.
  3. Process: Wait for your application to be processed, which may take several months, particularly during high-demand periods.
  4. Complete Documentation: Make sure all birth certificates, proof of Irish descent, and other documents are in order.

Looking Ahead

The trend of Irish passport applications from UK citizens is expected to continue as Brexit-related concerns persist and as individuals seek to secure EU benefits for themselves and future generations. The growing demand for Irish nationality highlights the enduring appeal of dual citizenship, especially in uncertain times.
