🇮🇪 Ireland vs Poland 🇵🇱
Ireland is the sprint, Poland is the marathon. An Irish grandparent claim is DIY, needs no archives work, and finishes in under a year. A Polish claim has no generational limit and can reach back further, but hinges on surviving pre-war records and a clean citizenship chain — often 2+ years and a Polish-speaking researcher. Choose Ireland for speed, Poland for reaching a deeper or non-Irish ancestor.
| 🇮🇪 Ireland | 🇵🇱 Poland | |
|---|---|---|
| Generational limit | Grandparent 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. | No fixed generational limit — claims going back to great-great-grandparents are possible if continuity of citizenship can be proven at every step. In practice, the further back you go, the harder continuity is to document, especially across the World War I, World War II and post-1945 border changes. |
| Process type | Registration (Foreign Births Register), or discretionary naturalisation | Confirmation of Polish citizenship |
| Timeline | 9–18 months (FBR); 12–19+ months (Naturalisation by Irish Association) | 1–3 years |
| Cost | $300–$800 DIY / $2,000–$5,000 agency | $1,000–$4,000 DIY / $5,000–$12,000 agency |
| Difficulty | Straightforward to Moderate (FBR); genuinely uncertain (Naturalisation by Irish Association) | Complex |
Ireland: no archives, no translations, ~8–10 months; Poland: archives-first, sworn translations, 1.5–2.5 years
Poland reaches great-grandparents+; Ireland effectively stops at grandparent
