Lithuanian Citizenship by Descent in 2026: The Pre-1940 Restoration Route

At a glance

Lithuania has one of the more accessible ancestry routes into the EU for the right family. If you descend from a person who held Lithuanian citizenship before June 15, 1940 (the start of the Soviet occupation) and who left Lithuania, you and your descendants may be able to restore Lithuanian citizenship. Two features make this stand out: in these restoration cases Lithuania generally lets you keep your existing citizenship, and there’s no language test, unlike Hungary’s route. That combination is rare.

The real catch is documentary, not linguistic. You have to prove your ancestor actually held Lithuanian citizenship in that narrow pre-1940 window, from a region whose borders, record systems, and record survival were shattered by occupation and war. For many families, especially the large Litvak (Lithuanian Jewish) diaspora, the line is real. The work is finding the paper.

The payoff is a full EU passport: the right to live and work across the EU, plus your US citizenship retained.

How it works: restoration, not ordinary naturalization

This route is built on restoration of citizenship to people who held it before the 1940 occupation and their descendants, rather than on ordinary naturalization. That framing matters, because it’s what unlocks two things ordinary naturalization doesn’t give: the descent reach across generations, and the retention of your existing citizenship.

• The reference point is June 15, 1940. The qualifying ancestor must have been a Lithuanian citizen before that date. The Migration Department reinstates citizenship for a person whose parent, grandparent, or great-grandparent (or the person themselves) was a citizen of Lithuania before June 15, 1940. That is the full reach: children, grandchildren, and great-grandchildren of the pre-1940 citizen. You have to prove the direct line back to that ancestor.
• Dual citizenship is retained in these cases, and this survived the 2024 referendum. Here’s the part people get wrong. Lithuania’s Constitution restricts dual citizenship, but there’s a standing exception for people who left or were exiled from occupied Lithuania before March 11, 1990 (the day independence was restored) and their descendants. Restoration cases sit inside that exception, so you keep your existing passport. The failed May 2024 referendum was about a different group entirely: it would have opened dual citizenship to people who emigrated after 1990. It fell short on turnout (about 59 percent turned out and 73.9 percent of them voted yes, but a constitutional change needs a yes from more than half of all registered voters). Because that vote never touched the pre-1990 exception, the restoration route was unaffected. If you qualify through a pre-1940 citizen who left before 1990, your right to hold both passports is the current, in-force rule, not something the referendum changed.
• No language test and no residency requirement for the restoration route, which is the key practical difference from Hungary. Restoration by descent is exempt from the language exam, the Constitution test, and any residency period. (The application form itself is completed in Lithuanian, but that’s paperwork, not a language test.)

What you have to show

• The ancestor’s pre-1940 Lithuanian citizenship. This is the load-bearing document and the hard part. Residence in the region is not enough; you need evidence the ancestor was a Lithuanian citizen before June 15, 1940. The Migration Department accepts pre-1940 Lithuanian internal or foreign passports, personal or identity certificates issued before that date, military or civil service records, and birth certificates or other records that state the ancestor’s citizenship directly. Where no citizenship document survives, records of studies, work, and life in Lithuania before June 15, 1940 can be used to build the case.
• The departure before March 11, 1990. For the dual-citizenship retention specifically, you show the ancestor (or the line) left or was exiled from occupied Lithuania before independence was restored on March 11, 1990. Emigration records, ship manifests, and naturalization abroad all speak to this.
• An unbroken documentary line from that ancestor to you: births, marriages, and name changes across every generation, frequently across languages and archives. Foreign-language documents have to be translated into Lithuanian and legalized or apostilled.

For Litvak families, Lithuanian and international Jewish genealogical archives are often the route to the pre-war records, and specialist researchers are a normal expense.

The honest filter

Strong candidates: anyone who can document an ancestor who was a Lithuanian citizen before mid-1940 and then emigrated. The absence of a language test and the retention of US citizenship make this one of the cleaner ancestry routes once the paper exists.

The wall: the pre-1940 citizenship proof. If the family story is “from Lithuania” but the records show only a village of residence in a border region, or nothing survives, the claim can stall on evidence even when the blood line is genuine. Assess the documents before you invest in the process.

Process, cost, and timeline

You apply to the Lithuanian Migration Department through its MIGRIS system. You submit the documentary line and the proof of the ancestor’s pre-1940 citizenship. If it’s approved, you get a decision reinstating citizenship, and then you can obtain a Lithuanian passport. In practice the Department does a preliminary check of your uploaded documents, then notifies you through MIGRIS to visit a consulate in person within four months to submit the originals.

The state fee for a citizenship application is 120 euros, and the Migration Department’s decision typically takes about 6 to 12 months once a complete file is in. Budget for longer overall: the archival research to find a pre-1940 citizenship record and assemble the generational line is usually the slow part, and specialist genealogists are a normal expense on this route. The dual-citizenship position, the generational reach, and the no-language-test rule are confirmed against the Migration Department (see the claim ledger). The exact fee should still be reconfirmed against the official state-fee schedule, which would not load on this verification pass. It has not been checked by a Lithuanian citizenship lawyer, so confirm that figure before you rely on it.

If a Lithuanian line isn’t your route, that doesn’t take leaving off the table. Our guide to leaving the US walks the wider set of exit paths, and retirement visas are the usual off-ramp when there’s no ancestry claim to lean on. If you’re weighing this against other ancestry options, our citizenship by descent hub compares the national routes side by side, including Poland by descent for the neighbouring line.

FAQ

Do I have to speak Lithuanian? No. The restoration route is exempt from the language exam, the Constitution test, and any residency period. The application form itself is completed in Lithuanian, but that’s paperwork, not a language test. This is the key practical difference from Hungary’s naturalization route.

Can I keep my US passport? Yes, in these restoration cases. Lithuania’s Constitution restricts dual citizenship, but there’s a standing exception for people who left or were exiled from occupied Lithuania before March 11, 1990 and their descendants. Restoration sits inside that exception, so you keep your existing passport. The failed 2024 referendum concerned only people who emigrated after 1990 and did not touch this exception.

My family were Litvaks who left before WWII. Do I qualify? Often yes, if you can document it. The large Litvak diaspora is exactly who this route fits. The test is that your ancestor held Lithuanian citizenship before June 15, 1940 and then left. For many families the blood line is real and the work is finding the pre-war paper, and Lithuanian and international Jewish genealogical archives are the common route to it.

How far back does it go? Great-grandparents? To great-grandchildren. The Migration Department reinstates citizenship for a person whose parent, grandparent, or great-grandparent was a Lithuanian citizen before June 15, 1940. There’s no fixed cap beyond proving the direct line back to that ancestor.

What proof do I need of the ancestor’s citizenship? Evidence that the ancestor was a citizen, not merely a resident, before June 15, 1940. The Migration Department accepts pre-1940 Lithuanian internal or foreign passports, personal or identity certificates issued before that date, military or civil service records, and birth records that state citizenship. Where no citizenship document survives, records of study, work, and life in Lithuania before that date can help build the case.

How long does it take? The Migration Department’s decision typically takes about six to twelve months once a complete file is in. Budget for longer overall, because the archival research to find a pre-1940 citizenship record and assemble the generational line is usually the slow part, and specialist genealogists are a normal expense on this route.
