Head to Head

🇮🇪 Ireland vs Italy 🇮🇹

Since Italy's 2025 reform, these two have swapped difficulty. Ireland is now the far easier claim: an Irish-born grandparent gives a clean, DIY, no-language Foreign Births Register case in roughly 8–10 months. Italy's administrative route is closed beyond a grandparent born in Italy, pushing most great-grandparent claims into slow, expensive court cases. If you have both lines, pursue Ireland first.

🇮🇪 Ireland🇮🇹 Italy
Generational limitGrandparent born in Ireland: straightforward. Great-grandparent: available in principle, but only if your parent registered on the FBR before your birth — in practice this stops most great-grandparent claims that weren't planned for in advance. Naturalisation by Irish Association has no fixed generational limit at all, since it runs on a discretionary connection test rather than a statutory descent formula — but it is correspondingly less predictable.Parent or grandparent for applications filed after the 2025 reform (Decree-Law 36/2025, converted into Law 74/2025). Appointments booked before 28 March 2025 are largely grandfathered under the old no-limit rules, and court cases (1948 path) may still proceed under pre-reform rules. Under active legal challenge — treat as unsettled.

Key Differences

  • Ireland: grandparent route open and DIY-friendly; Italy: two-generation limit since Law 74/2025
