Ireland is preparing its biggest overhaul of citizenship by naturalization rules in years, with the government backing plans to increase the general residence requirement from five years to eight and introduce language and civic knowledge tests.

On September 9, 2026, the Irish government approved priority drafting of the Irish Nationality and Citizenship (Amendment) Bill 2026. The proposed legislation would change several of the conditions applicants must satisfy before obtaining Irish citizenship through naturalization. 

The changes have not yet entered into force. Ireland’s existing citizenship rules continue to apply until new legislation is enacted and commenced.

Residence Requirement Would Rise From Five to Eight Years

The most significant proposed change is an increase in the qualifying period of reckonable residence from five years to eight years for most applicants.

Under Ireland’s current rules, an adult applying for naturalization generally needs five years of reckonable residence. This normally consists of one year of continuous residence immediately before the application and four additional years of reckonable residence during the preceding eight years. 

Under the proposed system, applicants would instead need eight years of qualifying residence.

The Irish Times has reported that the planned structure would require two years of continuous residence immediately before an application, together with six years of residence during the preceding 10 years. 

This would substantially lengthen the route to naturalization for foreign residents who currently qualify under Ireland’s five-year framework.

People Already Living in Ireland Could Be Affected

The proposed increase is also expected to affect people who are already accumulating residence toward citizenship but have not applied before the new legislation takes effect.

Justice Minister Jim O’Callaghan addressed the issue directly when asked about applicants approaching the existing five-year threshold. He said that a person who had accumulated four years and 10 months of residence when the new legislation commenced would be affected by the change. 

However, residence already accumulated would not simply disappear. Reporting on the proposal indicates that existing qualifying residence would count toward the new eight-year requirement. 

The exact commencement date and final transitional provisions will depend on the legislation ultimately enacted.

Language Testing Would Become a New Requirement

Ireland also plans to introduce a language requirement for citizenship by naturalization.

Under the proposed changes, applicants would be required to demonstrate proficiency in English, Irish or Irish Sign Language.

Ireland currently has no general language proficiency test for naturalization. In June 2026, the Department of Justice confirmed that no such requirement applied to citizenship applications at that time.

The government has not yet published the required proficiency level or the detailed format of the proposed assessment.

Justice Minister Jim O’Callaghan has described the planned language requirement as relatively straightforward, with the aim of ensuring applicants can communicate effectively and participate in Irish society. 

Economic Self-Sufficiency Would Form Part of the New Rules

The proposed reforms would also introduce an economic self-sufficiency requirement for citizenship by naturalization.

According to The Irish Times, applicants would be expected to show that they are financially self-sufficient, with certain social welfare payments potentially taken into account when eligibility is assessed.

Some payments, including child benefit and maternity benefit, are not expected to prevent an applicant from qualifying. Other forms of social assistance may be considered, particularly where they indicate longer-term dependence on State support.

The government has not yet published the complete list of affected payments or the final financial criteria.

The precise requirements will therefore depend on the final legislation and any accompanying regulations.

Other Changes Are Also Planned

The proposed legislation would also make several other changes to Ireland’s naturalization system.

Applicants who breach immigration law could be barred from obtaining citizenship, while the Minister for Justice would gain clearer powers to revoke naturalized citizenship on public order and national security grounds.

The government also plans to change the naturalization rules for foreign spouses and civil partners of Irish citizens, including increasing the period they must reside in Ireland before becoming eligible to apply. The exact new residence period has not yet been publicly confirmed.

Time spent in Ireland under the EU Temporary Protection Directive would also not count toward the residence period required for citizenship under the proposed rules.

What Does This Mean for Former Immigrant Investor Programme Participants?

The changes could also be relevant to investors and family members who obtained Irish residence through the country’s former Immigrant Investor Programme, or IIP.

Ireland closed the IIP to new applications on February 15, 2023, while applications already in the system continued to be considered. Successful applicants and qualifying family members receive Stamp 4 residence permission.

Stamp 4 is reckonable for citizenship by naturalization. However, the IIP itself does not provide a preferential route to Irish citizenship.

Ireland’s official IIP guidelines state that investors seeking naturalization must meet the ordinary citizenship requirements. They also make clear that only periods during which an investor is physically resident in Ireland count toward the residence requirement for naturalization.

The IIP allowed investors to maintain their residence permission without living in Ireland full time, but that flexibility does not automatically count toward the residence period required for citizenship.

Former IIP participants seeking Irish citizenship would therefore need to meet the naturalization requirements applicable to them at the time of their application. 

The Changes Are Approved for Drafting, Not Yet in Force

The distinction between the government’s proposal and current law is important.

As of September 14, 2026, the government has approved priority drafting of the Irish Nationality and Citizenship (Amendment) Bill 2026. The proposed changes have not yet replaced the existing five-year naturalization rule.

The legislation must still move through the legislative process before the new requirements can take effect.

If enacted in their proposed form, the reforms would materially change Ireland’s pathway from residence to citizenship. For most applicants, the qualifying residence period would rise from five years to eight years, while language proficiency and economic self-sufficiency would become new elements of the naturalization process.
