Czech citizenship by declaration — a quiet fast lane
If a parent or grandparent held Czech or Czechoslovak citizenship and lost it by emigrating, you may be able to claim Czech citizenship by simple declaration — one of Europe's most underrated routes: no language test, no residency, dual citizenship welcome.

2-minute anonymous interview — no real names or documents needed.
Who qualifies
Under Act 186/2013, children and grandchildren of former Czech or Czechoslovak citizens qualify if the ancestor lost that citizenship by 31 December 2013 — most commonly by emigrating and naturalising abroad in the communist era. The ancestor doesn't need to be living, and you don't need to speak Czech or ever have lived in Czechia.
Who doesn't qualify (yet)
- Great-grandchildren aren't covered — though a broadening amendment has been proposed in the Czech parliament, so this is worth monitoring.
- Descendants of ancestors who lost citizenship under the post-war decrees as persons of German or Hungarian nationality are excluded.
- Current Slovak citizens can't use this route, and it doesn't apply if the ancestor acquired Slovak citizenship after 1 January 1969 — those cases point to the Slovak route.
Documents you'd need
- Your ancestor's Czech/Czechoslovak documents — passports, citizenship certificates, or registry records
- Proof of how and when they lost citizenship (e.g. a U.S. naturalisation certificate)
- Birth and marriage certificates linking each generation down to you
- Certified Czech translations of foreign documents

Frequently asked questions
What does 'citizenship by declaration' mean?
It's a simplified procedure: instead of applying for naturalisation, you declare an existing right based on your ancestry. If the paperwork checks out, the state must recognise it — no discretion, no language exam.
My grandmother left Czechoslovakia in 1968 and became American — do I qualify?
Very likely yes, if she thereby lost Czechoslovak citizenship by the end of 2013 and her line runs to the Czech part of the federation. That's the classic case the law was written for.
My Czech ancestor is my great-grandparent — any options?
Not under the current declaration law, which stops at grandchildren. A parliamentary proposal to extend it to great-grandchildren exists, so it's worth checking back — or examine whether an intermediate generation (your parent) could declare first.
Does Czechia allow dual citizenship?
Yes, fully, since 2014 — you keep your existing nationality when you acquire Czech citizenship.
