For most people restoring Lithuanian citizenship through a parent, grandparent, or great-grandparent who held Lithuanian citizenship before June 15, 1940, an oath of allegiance is generally not required. This ancestry-based procedure is legally treated as the reinstatement of Lithuanian citizenship rather than the granting of a new citizenship status.
However, the answer can change when the term “restoration” is used to describe a different legal procedure. Lithuanian citizenship law distinguishes between reinstating historical citizenship, granting citizenship, and returning citizenship that a person previously lost. Some of these routes require an oath, while ancestry-based reinstatement usually does not.
US-based applicants should therefore check the precise legal basis stated in their citizenship decision and any instructions received through the Lithuanian Migration Information System, commonly known as MIGRIS.
Is an Oath Required for Citizenship Restoration by Descent?
An oath is generally not required when Lithuanian citizenship is reinstated under the historical citizenship provisions available to former Lithuanian citizens and their descendants.
This route commonly applies when an applicant proves that a parent, grandparent, or great-grandparent was a citizen of the Republic of Lithuania before June 15, 1940. Applicants may also need to document the family relationship, historical departure from Lithuania, name changes, and other facts relevant to dual citizenship eligibility.
Under this procedure, the applicant is not being naturalized as a new citizen. Instead, Lithuania recognizes and reinstates a citizenship right connected to the applicant’s family history. The Lithuanian citizenship oath requirements applicable to naturalization and certain other citizenship routes therefore generally do not apply to standard reinstatement cases.
Once the competent authority approves the reinstatement, the applicant should carefully review the decision and MIGRIS notification. If the decision does not contain an instruction to take an oath, the applicant should not assume that a separate Lithuanian citizenship oath ceremony must be arranged.
Why the Terms Restoration and Reinstatement Cause Confusion
English-language explanations often use “restoration,” “reinstatement,” and “reacquisition” interchangeably. Lithuanian citizenship law, however, treats several procedures as legally distinct.
Reinstatement generally refers to the historical right of people who held Lithuanian citizenship before June 15, 1940, and their eligible descendants to recover that citizenship. This is the procedure most frequently described as Lithuanian citizenship restoration by descent.
A different procedure may apply when a person personally held Lithuanian citizenship more recently, later lost it, and now seeks to have it returned. Citizenship may also be granted through naturalization, a simplified procedure, an exceptional procedure, or another legally recognized ground.
The Lithuanian citizenship oath of allegiance is associated with several of these citizenship-granting or citizenship-returning procedures. It is not automatically associated with every case described informally as “citizenship restoration.”
For that reason, applicants should rely on the legal basis written in the official decision rather than on the general English name used for the application.
Which Lithuanian Citizenship Routes May Require an Oath?
An oath is generally required when Lithuanian citizenship is granted through naturalization, granted under the simplified procedure, granted by way of exception, returned to a former citizen under the applicable return procedure, or acquired on certain other statutory grounds.
In these cases, the person normally becomes entitled to exercise the rights and duties of a Lithuanian citizen after completing the oath requirement, unless a legal exemption applies. Lithuanian law may exempt certain applicants, including children under 18 and people covered by specified incapacity provisions.
This distinction is particularly important for an applicant who previously held Lithuanian citizenship personally. Such a case may be legally different from an application based on the citizenship of an ancestor.
The term “Lithuanian citizenship reinstatement oath” can therefore be misleading. An applicant using an ancestry-based reinstatement route will usually not need an oath, while someone following a citizenship-return procedure may need to take one.
What Happens After Ancestry-Based Citizenship Is Reinstated?
After a positive decision, the applicant should first read the complete MIGRIS message and official citizenship decision. These documents establish the basis of the decision and may contain instructions concerning personal records, civil status documents, or the next administrative step.
In a standard ancestry-based reinstatement case, the next major step is usually applying separately for a Lithuanian passport or identity card. Citizenship approval does not normally mean that a passport will be issued automatically.
Before applying for Lithuanian identity documents, the person may need to ensure that their name, date of birth, place of birth, marriage information, and other civil status details are correctly recorded. Differences between Lithuanian records and US documents can require additional certificates, translations, apostilles, or record-registration procedures.
The absence of an oath requirement does not eliminate these administrative steps. It only means that an oath is generally not a condition between the reinstatement decision and recognition of citizenship status.
Official Lithuanian consular guidance confirms that applications for reinstatement are submitted through MIGRIS and that applicants living abroad may be instructed to present original documents at a Lithuanian diplomatic mission or consular post.
When Is the Lithuanian Citizenship Oath Taken?
When an oath is required, it is normally taken after the relevant decision granting or returning Lithuanian citizenship has entered into force and after the applicant has received instructions from the Lithuanian authorities.
The applicable period for completing the oath may depend on the citizenship route, the applicant’s existing nationality, and whether the person must provide evidence concerning the loss or renunciation of another citizenship.
Applicants should not calculate the deadline solely from the date when they first see an informal status update. The relevant date and deadline should be identified from the official decision or notification.
Failing to complete a required oath within the applicable period may affect the citizenship procedure. Anyone who receives an oath instruction should therefore confirm the deadline, required documents, appointment process, and location without delay.
Where Is the Lithuanian Citizenship Oath Taken?
When required, the oath may generally be taken at the Ministry of the Interior in Lithuania or at a Lithuanian diplomatic mission or consular post abroad.
The applicant normally receives information about the competent institution, appointment procedure, and documents that must be presented. The Lithuanian citizenship oath ceremony is a formal procedure during which the applicant makes the prescribed declaration and signs the relevant oath document.
Applicants should not attend a consular post without an appointment or assume that every Lithuanian diplomatic mission handles oath procedures in the same way. Availability and scheduling may depend on the applicant’s residence, the citizenship decision, and instructions issued by the competent authority.
Can the Lithuanian Citizenship Oath Be Taken Abroad?
Yes. When an oath is legally required, Lithuanian law generally allows it to be taken at a Lithuanian diplomatic mission or consular post outside Lithuania.
A US-based applicant may therefore be able to complete the procedure through the Lithuanian Embassy or an appropriate consular post rather than traveling to Lithuania. The applicant must still follow the official appointment instructions and confirm that the selected post is authorized to handle the oath in that case.
Taking the oath abroad does not mean that it can be completed informally, by sending a signed statement, or through an ordinary remote call. The applicant should follow the procedure specified in the official notification and should not rely on general information about online citizenship ceremonies unless the Lithuanian authorities expressly make such an option available for the individual case.
Does the Oath Require Renouncing US Citizenship?
The oath itself and the question of retaining US citizenship are related but separate issues.
Many US citizens applying for Lithuanian citizenship reinstatement through qualifying ancestors may be eligible to retain both citizenships under an exception in Lithuanian law. Eligibility can depend on when the former Lithuanian citizen left Lithuania, whether the person was exiled, the destination of departure, and the applicant’s relationship to that person.
In an ancestry-based reinstatement case that qualifies for dual citizenship, the applicant usually does not take an oath and does not renounce US citizenship merely because Lithuanian citizenship is reinstated.
For citizenship routes that do require an oath, an applicant may also need to provide documents concerning another nationality. The exact requirement depends on whether Lithuanian law permits the person to hold both citizenships and on the legal consequences imposed by the other country’s law.
Applicants should therefore avoid treating the oath as a general renunciation of all other citizenships. The effect of the procedure must be assessed according to the specific citizenship route and the applicant’s dual citizenship eligibility.
How to Confirm Whether an Oath Applies to Your Case
The most reliable document is the official Lithuanian citizenship decision. Applicants should identify whether it refers to reinstatement of citizenship based on historical citizenship, return of previously lost citizenship, naturalization, the simplified procedure, or another legal ground.
The MIGRIS account should also be checked for instructions, deadlines, appointment information, and requests for additional documentation. If an oath is required, the notification will usually explain what the applicant must do next.
Applicants should not arrange a Lithuanian citizenship oath ceremony merely because another applicant took an oath. Two cases that appear similar may have been decided under different legal provisions.
When the wording of the decision is unclear, the applicant may request clarification from the Migration Department through MIGRIS or contact the relevant Lithuanian diplomatic mission regarding the practical appointment procedure.
FAQ
Is an oath required after Lithuanian citizenship restoration?
An oath is generally not required when citizenship is reinstated through a Lithuanian parent, grandparent, or great-grandparent who held citizenship before June 15, 1940. An oath may be required under other routes, including naturalization, simplified granting, or the return of citizenship previously lost by the applicant.
Do descendants of former Lithuanian citizens take an oath?
Eligible descendants using the ancestry-based reinstatement procedure usually do not take an oath. Their application is based on reinstating a historical right to citizenship rather than granting citizenship through naturalization.
When is the Lithuanian citizenship oath taken?
When required, the oath is generally taken after the relevant citizenship decision enters into force and within the period stated by the Lithuanian authorities. The applicant should follow the deadline and instructions provided in the official decision or MIGRIS notification.
Where can the Lithuanian citizenship oath be taken?
A required oath may generally be taken at the Ministry of the Interior in Lithuania or at a Lithuanian diplomatic mission or consular post abroad. The location and appointment procedure should be confirmed through the official notification.
Can a US applicant take the Lithuanian citizenship oath in the United States?
A US-based applicant who is required to take an oath may generally be able to do so at an authorized Lithuanian diplomatic mission or consular post in the United States. The applicant should wait for official instructions and confirm the appointment requirements with the relevant post.
Is an oath required before applying for a Lithuanian passport?
In an ancestry-based reinstatement case, an oath is generally not required before the applicant applies for a passport. If citizenship was granted or returned under a route that requires an oath, the applicant will normally need to complete that requirement before citizenship documents can be issued.
Does taking the Lithuanian citizenship oath cancel US citizenship?
Taking the oath does not automatically determine whether a person loses US citizenship. The ability to retain both Lithuanian and US citizenship depends on the applicable Lithuanian dual citizenship exception and the person’s individual circumstances. Applicants should review the legal basis of their decision rather than assume that the oath itself requires renunciation.
