The TL;DR
Most UK nomads start their Europe planning with visas. But some should do one check first.
Post-Brexit, ancestry-based citizenship has become a serious mobility strategy for UK citizens. If you have family roots in an EU country, you may already have a route to EU citizenship that changes your planning entirely. No Schengen clock, no digital nomad visa, no employer-sponsored work permit required.
This edition covers which countries are worth checking, how the different routes work, and what an EU passport can and cannot solve.
Covered in this article
1. 🗺️ Why This Check Comes First
For UK passport holders, Europe now comes with a clock.
GOV.UK is clear: your total stay in the Schengen area must be no more than 90 days in every 180 days. Working there usually requires a work permit or visa on top of that. Employer compliance gets complicated fast.
EU citizenship changes the starting point entirely. EU citizens can live in another member state for up to three months with just a valid passport or ID card, stay longer once they meet conditions around work, study, or self-sufficiency, and after five years of legal residence can acquire permanent residence rights.
The European Commission confirms that EU citizens have the same right to work in another member state as nationals of that country.
That is a materially different position to a tourist visa with a 90-day ceiling.
Ancestry-based citizenship is not a magic shortcut. The rules vary significantly by country, and documents matter more than family stories. But for some UK citizens, it is one of the highest-leverage checks they can make before spending weeks comparing visa routes.
💡 Key Takeaway If an EU country appears anywhere in your family tree, check the official citizenship rules before you build your plans around a temporary visa.
2. 🔑 Three Types of Route
It helps to understand the landscape before you start digging
🌳 Route type 1: Direct parent or grandparent routes
The most common type. A country recognises you as a citizen because a parent or grandparent was born there or held citizenship.
Best example: Ireland.
🔍 Route type 2: Citizenship confirmation routes
Some countries pass citizenship automatically through generations, whether or not anyone ever claimed it. If your parent or grandparent was a citizen and never formally gave that up, you may already be a citizen without ever applying for anything.
The question here is not "can I apply?" It is "do I already qualify?"
Best example: Poland.
⚖️ Route type 3: Restoration routes
These exist where citizenship was stripped, denied, or lost due to persecution or historic injustice. More specialist than the other two types, and usually require professional guidance.
Best example: Germany.
Knowing which type applies shapes everything: the documents you need, the process you follow, and the realistic timeline.
3. 🌍 Countries Worth Checking
This is a starting-point overview, not legal advice. Rules change. Always verify with official sources.
🇮🇪 Ireland: Most relevant for UK readers
Who qualifies
If you or your parent were born on the island of Ireland before 2005, Ireland's Department of Foreign Affairs states you are an Irish citizen and can apply for a passport without first applying for citizenship.
If your grandparent was born on the island of Ireland, you may be able to register Irish citizenship through the Foreign Births Register. Once registered, you are an Irish citizen and can apply for a passport.
Documents needed
Birth certificates, marriage certificates, and death certificates across up to three generations, sometimes from multiple jurisdictions. It is a project, not an afternoon task.
Does it cover your family
Irish citizenship does not automatically pass to a spouse. If your partner wants Irish citizenship, they would need to qualify in their own right through ancestry, or apply for naturalisation after living in Ireland for a qualifying period.
Your children may also be entitled to Irish citizenship if you are an Irish citizen, though the timing of your own registration affects their eligibility, worth checking the rules for children born outside Ireland.
Processing time: Approximately 12 months for Foreign Birth Registration, per Ireland's Passport Service.
⚠️ Watch Out The island of Ireland includes both the Republic and Northern Ireland. This route is not restricted to people with roots in the Republic.
🇮🇹 Italy: Relevant for close ancestry, rules tightened in 2025
Who qualifies
Until 2025, Italy had one of the most generous citizenship-by-descent routes in Europe, with no generational limit in many cases. That changed.
Current consular guidance now requires all of the following:
A parent or grandparent who held exclusively Italian citizenship at the relevant time
That the citizen parent was resident in Italy for a set period
That the Italian ancestor had not naturalised elsewhere before the next generation was born
In practice, the great-great-grandparent routes many people assumed were still available are now significantly restricted or closed.
If your link is through a parent or grandparent who did not naturalise elsewhere before you were born, it is still worth checking. If the link is more distant, the 2025 changes are likely to affect your eligibility.
Documents needed
Birth certificates, marriage certificates, and proof of Italian citizenship and residence for the qualifying ancestor. Requirements can vary by consulate.
Does it cover your family
Italian citizenship can pass to children of Italian citizens born abroad, subject to the same conditions. A non-Italian spouse does not automatically acquire citizenship through marriage, though a naturalisation route may exist after a period of marriage and residence.
Processing time: Historically long. Check current wait times directly with your nearest Italian consulate before planning around this route.
🇵🇱 Poland: Potentially powerful if the chain was not broken
Who qualifies
Poland passes citizenship through generations automatically, unless it was formally given up.
If your parent or grandparent was Polish and never naturalised elsewhere, you may already hold Polish citizenship without realising it.
Polish consular guidance frames this not as a new application but as a confirmation: did citizenship pass down your line, and was it ever lost?
Documents needed
Birth certificates, marriage certificates, and any records relating to naturalisation or loss of citizenship for each generation. Applications go through Polish consulates in Belfast, Edinburgh, London, or Manchester.
Does it cover your family
Polish citizenship can pass to children of Polish citizens. A non-Polish spouse does not acquire citizenship through marriage automatically, but may be able to apply for naturalisation after a period of residence in Poland.
⚠️ Watch Out Polish citizenship may have been lost if an ancestor naturalised as a British citizen, particularly in the decades after World War Two. Whether that broke the chain depends on timing and circumstances.
🇩🇪 Germany: A specialist restoration route
Who qualifies
Germany is not a general "German grandparent = passport" route.
The German Embassy in the UK explains two specific groups may be eligible:
Victims of Nazi persecution who were forcibly deprived of German nationality, and their descendants
Descendants of people who lost or were denied German nationality due to persecution, who may have a legal entitlement to naturalisation under specific provisions
Documents needed
Evidence of the persecution and citizenship deprivation, plus documentation linking you to the affected ancestor.
Does it cover your family
Restored German citizenship can pass to children, depending on the specific provisions under which it is granted. A non-German spouse does not automatically acquire citizenship, but may be eligible to apply for naturalisation after a qualifying period.
⚠️ Watch Out This is a specialist route that requires professional legal guidance. Do not attempt to navigate it without expert help.
🇵🇹 Portugal and 🇭🇷 Croatia: Worth checking given where nomads want to live
Who qualifies (Portugal)
Portugal's official government portal lists having Portuguese parents or grandparents as one of the qualifying conditions. Procedures vary depending on:
Birthplace
Family nationality
Connection with the Portuguese community
This is a case-specific route rather than a straightforward checklist.
Who qualifies (Croatia)
Croatia includes descent from Croatian emigrants among its citizenship categories. Lineage and emigration evidence is required.
Neither route is simple, but both are worth a check because they overlap directly with places many UK nomads want to live.
Does it cover your family
Citizenship acquired through descent can generally pass to your children. A spouse does not automatically acquire citizenship through marriage in either country, but residence-based naturalisation routes typically exist. Check the specific rules for each country through official sources.
⚠️ Watch Out Neither route should be treated as a quick process. Both are document-heavy and case-dependent. Treat them as long-term planning projects rather than near-term solutions.
🇪🇸 Spain: A cautionary example
Spain's Democratic Memory Law created a time-limited route for descendants of people exiled during the Civil War and Franco era. The deadline for applications passed in October 2025. If you missed it, this route is closed.
Spain is included here as a reminder: citizenship-by-descent windows can close. If another country in your family tree has a time-limited scheme, check its status now rather than assuming it will still be available when you get around to it.
4. ✅ Your 30-Minute Family-Tree Audit
Before you do anything else, map the chain. You are looking for EU countries in your family history and any circumstances that might complicate the paper trail.
Questions to answer:
Where were your parents born? What citizenship did they hold at your birth?
Where were your grandparents born? Did they ever naturalise elsewhere?
Did anyone in the chain lose citizenship through marriage, naturalisation, or other means?
Are there adoptions, remarriages, name changes, or spelling differences that could affect documents?
Documents to locate:
Your own full (long-form) birth certificate
Your parents' full birth certificates and marriage certificates
Your grandparents' birth certificates, marriage certificates, and death certificates where required
Any naturalisation records, adoption papers, or official name-change documents
Official translations and apostilles where documents are not in English
Build a simple log, one entry per person:
You Country of birth / Citizenship at birth / Documents: full birth certificate
Parent 1 Country of birth / Citizenship at birth / Naturalised elsewhere? / Documents: birth certificate, marriage certificate
Parent 2 Country of birth / Citizenship at birth / Naturalised elsewhere? / Documents: birth certificate, marriage certificate
Grandparent 1 Country of birth / Citizenship at birth / Naturalised elsewhere? / Documents: birth certificate, marriage certificate, death certificate
Grandparent 2 Country of birth / Citizenship at birth / Naturalised elsewhere? / Documents: birth certificate, marriage certificate, death certificate
Once you have filled this in, flag any EU country that appears and check that country's official citizenship-by-descent rules.
If you have a partner, ask them to do the same. EU citizenship does not transfer to a spouse automatically, but if your partner has EU ancestry in their own right, that changes the picture for your whole household.
Next step: Start the log today. Even incomplete, it tells you where the gaps are.
5. 🚫 What EU Citizenship Does Not Solve
Worth being clear about this.
An EU passport improves your immigration and working rights across member states. It does not automatically resolve:
Tax residency: spending significant time in another EU country can make you tax-resident there. Citizenship does not change when that triggers.
Employer compliance: if your employer is UK-based, their obligations in another country remain. An EU passport is yours; it does not cover your employer.
Local registration: EU citizens staying more than three months in another member state are generally required to register with local authorities.
Healthcare: entitlement varies by country and residency status. An EU passport does not give you automatic access to every system from day one.
Banking, housing, and professional licensing: these depend on local residency rules, not citizenship alone.
💡 Key Takeaway EU citizenship solves the immigration layer. Tax, employer compliance, healthcare, and registration are separate puzzles. We cover those in earlier editions. Links in Resources below.

WHAT WE’RE READING
The Alchemist by Paulo Coelho
Paulo Coelho’s The Alchemist follows a young shepherd travelling from Spain across North Africa after recurring dreams convince him there is a different life waiting for him elsewhere.
The book has sold millions of copies partly because the story itself is simple. Leave what is familiar, pay attention to opportunities as they appear, and accept that most meaningful journeys begin before you fully understand where they are leading.
Read while thinking about visas, ancestry routes and moving abroad, it lands slightly differently. Less self-help, more reminder that geography quietly shapes the direction of people’s lives far more than they initially expect.
Still one of the books that seems to find people at exactly the right moment.
