Confirmation of nationality
Proof of origin, search and retrieval of documents
Confirmation of nationality is an important step for individuals who plan to undergo repatriation or apply for citizenship based on ancestry. Many European countries, Israel, and several other states offer the possibility of obtaining a residence permit or passport to descendants of specific ethnic groups. However, to qualify, one must prove not only their kinship with an ancestor but also that ancestor’s national affiliation.
Often, nationality becomes the key issue: birth or marriage certificates alone are not always sufficient to confirm a connection to the required ethnic community in a legally meaningful way. In such cases, archival documents come to the rescue, recording an individual’s nationality, as well as the nationality of their parents or even the entire family, helping establish a clear and authoritative chain of proof.

Which records can confirm nationality?
Confirmation of nationality is based on working with official sources. Most commonly used materials include:
- church records and civil registration documents
- personal files from places of study or employment
- military records containing information about origin
- marriage, birth, and death certificates where nationality may have been recorded directly
- population censuses in which your ancestors stated their national identity
- household and address books indicating the nationality of residents
How does the process of confirming nationality work?
Initial analysis
After receiving your request, we contact the client, clarify the available information about the relatives whose nationality needs to be verified, review the documents already in hand, and, if necessary, ask additional questions.
Archival search
We conduct searches in state and regional archives to locate documents where nationality is indicated. In some cases, the search may cover several regions or even multiple countries.
Confirmation of kinship
If needed, additional documents establishing your connection to the ancestor are prepared, such as birth, marriage, or death certificates and other relevant records.
Search results
Once all information has been collected, we prepare a report and provide all documents to the client. Our center does not handle notarized or court-certified translations, nor does it perform apostille services.
Timeframe and cost of nationality confirmation
The average timeframe for locating documents confirming nationality is from 4 to 8 months. The duration depends on the depth of archival research, the number of regions and countries involved, the presence or absence of initial documents provided by the client, and the overall volume of materials.
The cost starts at €200.
Who may need nationality confirmation?
Many people try to obtain certificates or archival extracts on their own but eventually face bureaucratic difficulties and problems when contacting archives: they may refuse to issue documents without a properly formulated request, and some collections may be undergoing restoration.
Our experience with such cases allows us to:

The nationality confirmation service can be useful for descendants of Jews, Poles, Germans, Greeks, Bulgarians, and other groups whose ethnic communities have repatriation programs; for individuals applying for citizenship based on ancestry (for example, Poland, Hungary, Romania, Germany); for those applying for a residence permit on the basis of ethnic origin; and for families wishing to document their lineage. The result of the service is a document or a set of documents officially confirming the nationality of an ancestor. If necessary, the client also receives materials proving their kinship with this person, allowing them to begin the repatriation procedure.
Jewish ancestry often becomes the basis for repatriation to Israel under the Law of Return, as well as for obtaining citizenship in several European countries. The main difficulty lies in the fact that Soviet documents did not always record ethnic affiliation, or it could have been altered for various reasons.
Sources that can confirm Jewish origin:
For many Jewish families who lived in Eastern Europe, documents are preserved in the archives of Ukraine, Belarus, Moldova, Lithuania, Latvia, and Russia. Sometimes indirect evidence must be used, such as census mentions or documents belonging to the parents.
Sources that can confirm Jewish origin:
- civil registration records (birth, marriage, and death certificates with ethnicity indicated);
- records of Jewish communal registers;
- population censuses;
- personal files from places of work or study;
- documents related to repression or forced resettlement.

Polish roots allow one to apply for the Pole’s Card and live in Poland. The legal requirement is to prove the ethnic affiliation of an ancestor and pass an exam on language and cultural knowledge.
Sources of information:
Ethnic affiliation was often confirmed indirectly through Roman Catholic faith. The search is complicated by the fact that the territories of modern Belarus, Ukraine, and Lithuania once belonged to Poland, and therefore most documents remain within modern national archives.
Sources of information:
- Catholic parish registers;
- civil registry records with a nationality field;
- Austro-Hungarian and Russian Empire censuses;
- school documents;
- military and employment files;
- records related to repression or displacement.

German roots open the path to obtaining German citizenship. Large German communities historically lived in Russia, Ukraine, Latvia, and Estonia.
Sources of information:
Soviet archival records from the deportation period are especially important, as they clearly documented the ethnic category “German.” Research often covers archives of the Volga region, Siberia, Kazakhstan, and the Baltic states.
Sources of information:
- Protestant and, less frequently, Catholic parish registers;
- household and residency books;
- population censuses;
- military documents;
- files on deportations and repression;
- archives related to labor armies and resettlement.

Hungarian citizenship can be obtained by descendants of ethnic Hungarians. Many such families lived not only in Hungary but also in Transcarpathia, Slovakia, Romania, and Serbia.
Documents that record Hungarian ancestry:
After the dissolution of the Austro-Hungarian Empire, many Hungarians found themselves outside its borders. As a result, archives relevant to the search are scattered across several countries, and the work is often carried out simultaneously in different regions.
Documents that record Hungarian ancestry:
- Catholic and Reformed parish registers;
- civil status records;
- school and university files;
- Austro-Hungarian military documents;
- Austro-Hungarian censuses;
- Soviet-era documents with an ethnicity field.

Romanian or Moldovan origin serves as grounds for obtaining Romanian citizenship. Most descendants of Romanians and Moldovans live in Moldova and southwestern Ukraine, where Romanian administration functioned until 1940.
Documents confirming ethnicity and citizenship:
The work involves pre-war documents preserved in archives. They may be written in Romanian, requiring specialized knowledge for accurate interpretation.
Documents confirming ethnicity and citizenship:
- Orthodox parish registers;
- civil registry documents issued before 1940;

Estonian origin allows descendants of ethnic Estonians to restore Estonian citizenship or obtain a residence permit.
Documents where information appears:
A significant portion of the sources is preserved in Estonia and written in Estonian. It is also important to consider migration patterns: many families moved to Russia (Leningrad region, Siberia, the Urals), so research often takes place in several regions simultaneously.
