What Is Citizenship by Descent?

This is where citizenship by descent becomes technically demanding, and where working with an expert matters most. The most common disqualifiers across European programs include naturalization (an ancestor who became a citizen of another country, including the United States, typically lost their original citizenship at that moment, and whether children born before or after are affected depends on the exact date and the country's law), pre-independence emigration (Poland, for example, did not exist as an independent nation between 1795 and 1918, so an ancestor who left before 1918 may never have held Polish citizenship), gender-based transmission rules (older laws in many countries only let citizenship pass through the father, with relevant dates such as 1951 in Poland, 1975 in Germany, and 1948 in Italy), and renunciation (a formal renunciation by an ancestor severs the chain at that point). Understanding which apply to your family's history is the first and most important step in any case we take on.

It depends entirely on the country. Austria (in certain circumstances), Germany, Hungary, Poland, Luxembourg, Portugal, and Ireland allow the line to extend well beyond grandparents under the right circumstances. There are other programs which also technically have unlimited generational limits, depending on your own family's situation. Slovakia limits eligibility to parent, grandparent, or great-grandparent (and sometimes great-great grandparent), and Italy's 2025 law change narrowed the scope to parent or grandparent for new applicants, though this new law is being challenged at the European Court of Justice. What matters in every case is not just how far back your ancestor is, but whether citizenship passed cleanly through each generation between that ancestor and you. A break anywhere in the chain, whether caused by a naturalization, a female ancestor having a child before the relevant date, or a renunciation, can end eligibility regardless of how recent the qualifying ancestor is.

The documentary backbone of any application is a complete vital records chain: birth, marriage, and death certificates for every person in the direct line from your ancestor to you. Depending on the country, you may also need naturalization records, census records, church registers, military booklets, passports, or archive confirmations. Many documents require certified translation, and some require apostille authentication. Building this chain, tracking down records that may be a century old, and filling gaps where documents no longer exist is the most time-consuming part of the process, and where most self-guided applicants run into trouble.

No. Citizenship by descent is not an immigration process. You are not asking a foreign government to admit you. You are asserting a legal right that already exists under their law. In most programs, if you qualify, you are already a citizen, and the application is simply the formal recognition of that status. That is why many countries call it “confirmation” or “recognition.” It also means citizenship by descent generally does not require you to move to the country, learn the language, or demonstrate ties to the nation.

The United States allows dual citizenship, and many of the countries we work with do too. Rules differ by country, so we confirm yours during your free review, before you apply.

Timelines vary dramatically by country, filing pathway, and current processing volumes. Luxembourg's Article 7 process, handled entirely by mail, can conclude within a year. Others involve consular waitlists, court proceedings, or government review periods that stretch to two years or more. We provide realistic timeline expectations for your specific case and country during your consultation.

Yes. Canada is not European, but we help clients claim Canadian citizenship by descent along with citizenship in 14 European countries. If you have a Canadian parent or grandparent, a free review will show whether you qualify.
