Reinstatement, Not Naturalisation
This is the distinction the whole page turns on, and it's the reason citizenship by descent is such a different proposition from ordinary immigration.
Lithuania doesn't grant you citizenship because your grandmother was Lithuanian. The legal position is that you already have a right to it, and you are asking for it to be reinstated. That framing has real consequences: no residency requirement, no language exam, no Constitution test, and โ critically โ no requirement to give up your existing nationality, provided you meet the conditions below.
The core rule, in the state's own words
Persons who were citizens of the Republic of Lithuania until 15 June 1940, and their descendants who have not already acquired Lithuanian citizenship, have an indefinite right to reinstate it โ irrespective of the country in which they reside.
Two words in there matter enormously. "Indefinite" means there is no deadline and, notably, no stated generational cut-off โ unlike several other European ancestry programmes that stop at grandparents. "Irrespective of the country" means you never have to live in Lithuania, or even visit beyond one consular appointment.
The Dates That Decide Everything
Three dates govern almost every case. Get these straight and you'll immediately know whether it's worth pursuing.
Too early
Lithuania restored its statehood on 16 February 1918. Before that date there was no Lithuanian citizenship to hold. If your ancestors emigrated in, say, 1905 โ as very many did โ they most probably never held Lithuanian citizenship, and there is nothing to reinstate.
The qualifying window
Your ancestor must have been a citizen of the Republic of Lithuania at some point in this period. 15 June 1940 is the date of Soviet occupation. This is the window everything hinges on.
The dual citizenship test
To keep your current nationality alongside Lithuanian, your ancestor must have been deported before 11 March 1990, or have left Lithuania before 11 March 1990 โ meaning their permanent residence on that date was not in Lithuania. 11 March 1990 is the date Lithuania declared independence restored.
The single most common disappointment. Enormous numbers of people emigrated from what is now Lithuania during the late 1800s and early 1900s โ to the US, South Africa, the UK and elsewhere. Those departures predate the existence of Lithuanian citizenship. Ancestry alone isn't the test; your ancestor's legal citizenship status between 1918 and 1940 is. Establish this before spending money on anything else.
Are You Eligible?
Work through these in order. A "no" at any stage generally ends the reinstatement route.
Was your ancestor a citizen of Lithuania between 16 Feb 1918 and 15 June 1940?
Not merely born there. Not merely resident there. A citizen. This is the threshold question.
Can you prove it with documents?
The burden is on you, and it must be documentary. Family knowledge isn't enough.
Can you prove the chain of descent to yourself?
Birth and marriage certificates linking each generation, with name changes accounted for.
Have you already acquired Lithuanian citizenship?
The right applies to descendants who have not already acquired it.
If you want to keep your current nationality โ does your case meet the 11 March 1990 test?
Deported before that date, or permanently resident outside Lithuania on it.
Dual Citizenship
Lithuania is generally restrictive about dual nationality. Reinstatement is the significant exception.
Dual citizenship is permitted for people seeking reinstatement who:
- were deported from occupied Lithuania before 11 March 1990, or
- left Lithuania before 11 March 1990 โ that is, their permanent place of residence on 11 March 1990 was not in Lithuania
and/or their descendants.
โ Typically qualifies
- Fled or deported during the Soviet occupation
- Emigrated in the interwar period, 1918โ1940
- Displaced by the Second World War
- Descendants of any of the above
โ Needs careful advice
- Ancestor still resident in Lithuania on 11 March 1990
- Emigration date genuinely unclear
- Ancestor moved elsewhere within the former USSR
- Your own country restricts dual nationality
Check your other country too. Lithuania permitting dual citizenship doesn't mean your existing country does. Some nationalities are lost automatically on voluntarily acquiring another. Confirm the position on both sides before you file โ this is not a question Lithuania will answer for you.
What Actually Proves Citizenship
This is where most applications founder, so it's worth being precise.
The state's requirement is that you produce documentation directly indicating, or implicitly proving, your ancestor's Lithuanian citizenship. Documents showing only that they were born in, or lived in, the territory are not sufficient.
| Document | Proves citizenship? |
|---|---|
| Interwar Lithuanian passport | โ Strongest evidence |
| Lithuanian internal ID / citizen's card | โ Strong |
| Lithuanian military service records | โ Strong โ implies citizenship |
| Interwar census or population register entries | โ Often accepted |
| Lithuanian-issued civil records, 1918โ1940 | Can help build the case |
| Emigration or naturalisation papers naming Lithuania as prior nationality | Can help build the case |
| Birth certificate showing birth in the territory | โ Not on its own |
| Family tree, oral history, DNA test | โ No evidential value here |
Foreign records can be the key that unlocks it
If Lithuanian records were lost โ and many were, through war and occupation โ documents held in your own country may still establish citizenship. US naturalisation petitions, ship manifests, alien registration files and interwar visa applications frequently record the applicant's nationality as Lithuanian. That's exactly the kind of implicit proof the Migration Department will consider. Don't give up because a Lithuanian archive came back empty.
Finding the Documents
- Lithuanian State Historical Archives hold interwar civil, military and population records. Records survive unevenly by region and period.
- Your own country's national archives โ immigration, naturalisation and alien registration files are often the richest source, and easier to access.
- Ship manifests and passenger lists, which routinely record nationality.
- Jewish genealogical archives if relevant โ see below.
- Professional researchers in Lithuania. If archives are proving difficult, a specialist who knows the record systems is often cheaper than months of your own failed searching.
Expect this stage to take months, and to be the bulk of the work. The application itself is administrative; the research is the project.
The Application Process
Applications for reinstatement are submitted electronically through MIGRIS, the Lithuanian Migration Information System, personally by the applicant โ not by a representative.
Establish citizenship and gather documents first
Don't open an application until you have the evidence. This stage is the real work.
Legalise and translate
Foreign documents generally need an apostille and certified translation into Lithuanian.
Submit through MIGRIS yourself
Personally โ the system requires the applicant to file. Upload your documents and indicate that you'll present the originals at a consulate.
Wait for the preliminary assessment
The Migration Department reviews the uploaded documents first. This is genuinely useful: deficiencies surface before you travel anywhere.
Receive the MIGRIS notification โ then book
If there are no deficiencies, you'll be messaged through MIGRIS telling you to attend a consulate within 4 months with the originals. Only after this notification can you register for the appointment โ don't try to book earlier.
Attend the consulate with originals
The consular officer verifies your original documents and returns them to you. They aren't retained.
Wait for the decision
Then, if granted, apply for your passport or ID card.
The four-month window is the bit people miss
You cannot book a consular appointment whenever you like. The sequence is: submit via MIGRIS โ preliminary assessment โ notification โ then you have four months to attend with originals. If your nearest consulate has long waits, start looking at availability the moment that notification arrives.
โ Still to confirm. Current processing times (secondary sources suggest 6โ12 months, which is plausible but unverified), the state fee for reinstatement, and whether requirements differ by consulate. Confirm with the Migration Department or your nearest Lithuanian consulate.
Lithuanian Jewish Ancestry
Lithuania โ Lita in Yiddish โ was one of the great centres of European Jewish life, and Vilnius was known as the Jerusalem of the North. A very large number of people worldwide have Litvak ancestry, and the same reinstatement route applies.
The practical considerations are distinctive:
- The 1918โ1940 citizenship test applies identically. Jewish residents of interwar Lithuania were Lithuanian citizens, and interwar documentation often survives.
- Emigration timing matters as much as anywhere. Families who left in the great wave before 1918 generally fall outside the window; those who left in the 1920s and 1930s generally don't.
- Holocaust-era displacement raises specific evidential questions. Records may exist in Israeli, German, Russian or international archives rather than Lithuanian ones.
- Jewish genealogical resources โ LitvakSIG, JewishGen and the Lithuanian State Historical Archives โ have indexed substantial holdings.
Given the evidential complexity, this is an area where specialist help tends to pay for itself.
Is It Worth It?
Lithuanian citizenship is EU citizenship. That's the substance of it.
What you gain
- โ Live, work and study anywhere in the EU/EEA
- โ No visa or permit needed across 27 countries
- โ EU passport and freedom of movement
- โ Passes to your children
- โ Access to EU healthcare and education systems
- โ You can keep your current nationality, if eligible
What to weigh
- โ Research can take months and cost money
- โ Records may simply not survive
- โ Possible tax and military service implications
- โ Your other country may object to dual nationality
- โ No guarantee of success
Take tax advice before you file, not after. Acquiring an additional citizenship can have tax consequences depending on your circumstances and your other nationality โ US citizens in particular should understand their position first. It rarely changes the answer, but it's much better known in advance.
One immediate practical benefit
Even before citizenship is granted, people who have submitted documents proving Lithuanian origin โ or the right to restore citizenship โ are exempt from the state fee for residence permit administration. If you're moving to Lithuania while your reinstatement case runs, that's worth knowing. See our residence permit guide.

Why Applications Fail
Proving residence instead of citizenship
By far the most common failure. A birth certificate showing birth in Kaunas proves birth in Kaunas. It does not prove citizenship.
Ancestors who left before 1918
There was no Lithuanian citizenship to hold. Check the emigration date before anything else.
Gaps in the chain of descent
Every generation between the ancestor and you needs documenting. Name changes on emigration are a frequent complication โ Lithuanian surnames were often altered at the border.
Assuming the dual citizenship rule is automatic
It depends on the 11 March 1990 test. Not every eligible applicant qualifies to keep their existing nationality.
Trying to book a consulate appointment too early
You can only register after MIGRIS notifies you. Attempting it earlier wastes time.
Missing the four-month window
Once notified, you have four months to present originals. Diarise it immediately.
Filing through a representative
The application must be submitted personally by the applicant through MIGRIS.
Frequently Asked Questions
How far back can I claim?
The law describes an indefinite right for descendants, with no stated generational cut-off โ unlike several other European ancestry programmes. What limits most cases in practice is evidence, not generations: the further back you go, the harder it is to document citizenship and the chain of descent.
Do I have to live in Lithuania?
No. The right applies irrespective of where you reside. Most applicants never live in Lithuania, and the only in-person step is a consular appointment to present original documents.
Do I need to speak Lithuanian?
No. Reinstatement has no language requirement โ that's a naturalisation requirement, and this isn't naturalisation. Your documents will need certified translation into Lithuanian.
Can I keep my current citizenship?
Yes, if your case meets the 11 March 1990 condition โ deported before that date, or permanently resident outside Lithuania on it โ or you're a descendant of someone who was. Also check whether your other country permits dual nationality.
My ancestor was born in Lithuania. Is that enough?
No โ and this is the most important point on the page. You must prove they were a citizen of the Republic of Lithuania between 16 February 1918 and 15 June 1940. Birth or residence in the territory alone is not sufficient.
What if the Lithuanian records were destroyed?
Look in your own country. Naturalisation petitions, alien registration files, ship manifests and visa applications frequently record Lithuanian nationality, and can serve as implicit proof.
How long does it take?
The research usually takes far longer than the application. Secondary sources suggest 6โ12 months for processing once filed, though we haven't confirmed that officially โ check with the Migration Department.
Does my child get citizenship too?
Descendants of Lithuanian citizens hold the same right, so children can generally be included or apply separately.
Is this the same as the Karta Polaka or similar cards?
No. This is full citizenship โ an EU passport with complete rights โ not an ancestry card conferring limited privileges.
What if my ancestor was Jewish?
The same rules apply. Jewish residents of interwar Lithuania were Lithuanian citizens. The evidential picture differs because of wartime destruction and displacement.
