Nationality rules differ enormously between countries, and this is not a page that can tell you whether you qualify. Some countries pass citizenship down indefinitely; others stop at one generation born abroad, require registration before a deadline, or do not permit dual nationality at all. What follows is how to find out for Lithuania, and what to settle before you spend anything.
Quick facts
Lithuania has six consular offices, in Chicago, Los Angeles, New York, Palm Beach, St Petersburg and Washington, D.C. That is enough offices for the kind of office to matter as much as the distance to it.

View details โThe questions that decide your case
- How far down does descent run? Through a parent is common; through a grandparent is much rarer; through a great-grandparent is unusual anywhere.
- Is there a deadline? Several countries require a child born abroad to be registered within a set period, after which the claim is lost.
- Does Lithuania permit dual nationality? As a rule, no. A Lithuanian who acquires another citizenship loses the Lithuanian one on the day of acquisition, whether they are Lithuanian by birth or not. The exceptions are narrow and mostly historical โ check whether one applies to you before you do anything else.
- Does the line pass through either parent? Some nationality laws were paternal for decades and were reformed later, sometimes with retroactive effect.
- What obligations come with it? Military service and tax residence attach to nationality in some countries regardless of where you live.
Documents a claim by descent normally rests on
- Birth certificates establishing the unbroken line, each certified for use abroad.
- Marriage certificates covering every change of surname in that line.
- The ancestor’s Lithuanian passport, identity card or other proof of nationality.
- Evidence of whether and when an ancestor naturalised elsewhere, which in some countries breaks the line.
- Translations into Lithuanian where required.
Before spending money on this
Ask the consular office what Lithuanian law actually allows in your circumstances before engaging anyone to help with it. Genealogists and specialist firms exist and can be useful where records are old or scattered, but they are not a substitute for knowing whether the claim exists at all โ and that answer is free.
If your own immigration position in the United States is unresolved, take advice from an immigration lawyer before approaching any foreign authority.
Lithuania: loss is automatic, and dated to the day
Article 26(1) of the Law on Citizenship states that a citizen of the Republic of Lithuania who has acquired the citizenship of another state loses Lithuanian citizenship from the date of that acquisition, except for the persons listed in Article 7. The law entered into force on 1 April 2011. There is no distinction between citizens by birth and by naturalisation: the carve-outs are about circumstances, not about how you became Lithuanian.
The exceptions that are carved out of the loss rule are Article 7, subparagraphs 1 to 5 and 7. In practice, for someone naturalising in the United States, the ones that matter are:
- a person exiled from occupied Lithuania before 11 March 1990 who acquired another citizenship;
- a person who fled Lithuania before 11 March 1990 and acquired another citizenship;
- a descendant of either;
- a person who acquired both citizenships at birth and has not yet turned 21.
The marriage exception does not help here: it covers a foreign citizenship acquired automatically by the fact of marriage, and U.S. citizenship is never acquired that way.
There is also a duty afterwards. Article 26(2) requires the person to notify an authorised Lithuanian institution, or a Lithuanian diplomatic mission or consular post, in writing within two months of acquiring the other citizenship. Article 26(3) attaches liability to failing to do so.
Checked on 6 October 2026 against the Law on Citizenship No. XI-1196 as published by the Seimas. That is the law as adopted in 2010; we could not open the consolidated version, so confirm the current wording of Article 7 with the consulate before relying on an exception.
