Citizenship by descent is the process of gaining citizenship through ancestry where at least one parent, grandparent, or even great-grandparent was a citizen of a country. Each country has its own eligibility criteria. Some require a direct parental connection, while others accept more distant ancestors.

Depending on the country’s laws, applicants may need to renounce their foreign nationality in some cases. The process includes submitting proof of ancestry, such as birth certificates and family records, to the immigration authorities for approval.

This guide will explain how to get citizenship through ancestry, the different types of citizenship by descent, the application process, the advantages, and the countries that offer second passports through descent.

Citizenship by descent, also known as ancestry-based citizenship, allows individuals to claim citizenship based on their family lineage, usually through a parent or grandparent born in that country.

A person may be eligible if their parents, grandparents, or even great-grandparents come from a specific country. This path is becoming more popular as a way to obtain second citizenship in a foreign country.

There are three types of citizenship by descent.

  1. Citizenship by descent at birth: Some countries grant citizenship by descent if a child’s parents are citizens, as shown on the birth certificate.
  2. Citizenship by descent after birth: It allows a child with foreign citizenship to claim dual citizenship by proving a family link, often through parents or grandparents
  3. Citizenship by ethnicity: This is based on a person’s cultural or ethnic background. People with Sephardic ancestry, for instance, may claim Spanish citizenship, while Indigenous peoples in countries like Canada and Australia have protected cultural and land rights under international law.

Benefits of Acquiring Citizenship by Descent and Second Passport  

Getting dual citizenship through a second passport by descent offers valuable benefits, including visa-free travel, social advantages, and the right to participate in the country’s economy and politics.

Here is a breakdown of some of the benefits of claiming citizenship by descent:

GCS-ICONS-56Enhanced mobility

Getting second citizenship by descent allows visa-free travel to more countries and provides a second passport as a backup. Some, like EU citizenship, also grant the right to live in any EU country.

Expanded educational opportunities

Having additional citizenship citizenship allows access to a wider range of educational opportunities, including prestigious universities and schools. It can also eliminate or lower international student fees, making education more affordable. Dual citizens can choose from diverse educational systems, programs, and cultural experiences.

GCS-ICONS-52Cultural heritage

Restoring citizenship through ancestral ties helps individuals reconnect with their heritage, customs, and language, strengthening their cultural identity. Future generations can also benefit by preserving their family’s heritage and enjoying citizenship rights.

GCS Icon EurosExpanded investment opportunities

Getting dual citizenship and a second passport provides economic opportunities, such as access to more investment markets, tax benefits, and business options. It also helps avoid foreign ownership restrictions in countries like the UAE, Montenegro, Thailand, and Singapore.

GCS-ICONS-08Political empowerment

Individuals with dual citizenship can vote in elections, run for public office, and have a voice in shaping policies and decisions that affect their lives and the communities they belong to. An additional passport comes with the right to participate in the political affairs of two countries actively.

GCS-ICONS-04Extended civil liberties

Second citizenship obtained through citizenship by descent offers a wider range of legal protections, including the right to live, work, and own property in multiple jurisdictions. Also, dual citizenship can provide individuals with increased social and economic rights, such as access to healthcare, social programs, and education.

Eligibility Criteria for Citizenship by Descent

Different countries have different rules for granting citizenship by descent. Some may not allow it for children born abroad, for parents who didn’t live in the country for a required number of years before the child’s birth, or for specific relatives. Regardless, applicants must provide sufficient evidence of their ancestry.

Here are the two most common criteria for citizenship through ancestry:

  • Direct lineage: To be eligible for citizenship by descent, individuals usually need to establish a direct ancestral connection to a citizen or national of the country in question.
  • Proof of ancestry: Proving lineage requires legal documentation to prove the ancestral link. General legal documents include the ancestor’s birth certificate, marriage records, or other official documents that verify the ancestor’s citizenship and connection to the applicant. All the required documents in foreign languages must also be legalized before submission.

Note: In special cases, such as when parents are deceased, death certificates may be required to establish eligibility for citizenship by descent. In some countries, legal guardians can transfer eligibility if the parents are unavailable or deceased.

How to Get Citizenship Through Ancestry

Step one: Determine eligibility

You must first ask:

  • How many generations back can I go? Do I need to apply through my grandparents, or can it be more distant ancestors in the direct line?
  • Are there any limitations concerning the paternal or maternal side?
  • Does it matter if my ancestors were not citizens by birthright?
  • Which specific documents will I need to submit?

It is not possible to prove your eligibility for citizenship based on a DNA test and presenting the results to immigration officials. The entire process will require a much deeper dive into your family’s history by searching through genealogical archives and identifying the location of official documents suitable for citizenship purposes.

Step two: Prepare your application

You will need to prepare the documents to accompany your application form. This information can be obtained from the embassy or the official government website. Typical documents for an ancestral passport include:

  • Your birth certificate
  • Your passport
  • Official records of your ancestors (birth certificates, marriage/divorce certificates, death certificates)
  • Legal name change documents (if applicable)

All documents in a foreign language must be translated into the country’s official language and carry an apostille seal.

Step three: Attend interviews or examinations

Depending on the country’s specific requirements or the condition of your documentary evidence, you might be asked to participate in interviews or examinations to further evaluate your eligibility for citizenship through descent. In preparation, ensure you study the country’s relevant historical, linguistic, or civic references.

Step four: Await the decision

Once you have submitted your application and fulfilled any required interviews or examinations, you will need to wait for the final decision on your citizenship request. The timeline for acquiring citizenship by descent varies widely as it is contingent on each country’s processing procedures and bureaucratic systems.

Step Five: Apply for the passport

After receiving approval, obtain the required documentation, including a citizenship certificate. 

Special Limitations of Citizenship by Descent

  • Generational limits: Some countries limit how many generations can pass down citizenship.
  • Residency requirements: Ancestors may need to have lived in the country for a set time before thepassport descendant’s birth.
  • Type of citizenship: Citizenship passed down depends on whether the ancestor was a citizen by birth or naturalization.
  • Maternal/paternal lineage: Some countries only allow citizenship through the father, not the mother.
  • Renounced citizenship: Ancestors must not have given up their citizenship or taken another citizenship.
  • Legal changes: Historical events and law updates can affect eligibility, and getting professional and legal advice can speed up the process.
  • Birth abroad: Birth abroad complicates citizenship claims due to varying laws. For example, U.S. children born overseas must prove their parents lived in the U.S. before their birth. It’s more complex for those born on military bases or U.S. vessels.

Alternatives to Citizenship by Descent 

Citizenship by investment

Citizenship by investment allows individuals to get a second passport by making significant financial contributions to a country’s economy. These investments can include real estate, businesses, or government bonds.

Citizenship by investment programs are ideal for those without ancestral ties. They often have no residency or language requirements and provide benefits like faster processing, global mobility, and potential tax advantages.

Citizenship by naturalization

Citizenship by naturalization refers to acquiring citizenship of a country by meeting requirements, the most common of which being residency duration.

For instance, one could become an Italian citizen by naturalization after legally residing in Italy for 10 years. Each country has its own rules, including language proficiency, understanding of the country’s laws, an oath of allegiance, and passing a citizenship test.

Frequently Asked Questions about Citizenship by Descent

What is citizenship by descent?

Citizenship by descent, also called citizenship by ancestry, is a process that allows individuals to get citizenship in a country based on their family ties. It’s different from birthright citizenship, which is when someone is granted citizenship in the country in which they were born.

Can I claim citizenship through ancestry?

Yes, you can claim citizenship through ancestry if you have a parent, grandparent, or sometimes even a great-grandparent from a country that offers citizenship by descent. Each country has different rules, so you’ll need to provide proof of your ancestral connection through official documents.

Can you get citizenship by DNA test?

A DNA test alone typically cannot grant citizenship. While some countries may use DNA to verify ancestral connections, citizenship usually requires official documentation like birth certificates or records. DNA tests can support your claim but are not the sole proof for obtaining citizenship.

How do I prove my ancestry for citizenship?

To prove your ancestry for citizenship, you typically need to provide birth certificates, marriage records, or other official documents that trace your lineage. The exact requirements vary by country, so it’s important to check the specific criteria for the country you’re applying to.

Can I get citizenship through my great-grandparents?

Yes, some countries allow citizenship through great-grandparents, but it depends on the country’s laws. Countries like Ireland and Italy have provisions for descendants of earlier generations, but you may need to provide sufficient proof of ancestry and meet other specific criteria.

What is the easiest citizenship by ancestry?

Italian citizenship by descent is often considered one of the easiest options for obtaining citizenship through ancestry, as there are generally no generational limitations. Alternatively, you can get Portuguese citizenship by descent if you have a qualifying ancestor, such as a parent or grandparent.

 

How many generations back can you claim citizenship?

The number of generations you can go back to claim citizenship varies by country. Some, like Italy and Ireland, allow claims through grandparents or even great-grandparents. Others, such as Germany or Poland, may have stricter criteria, often limited to parents or immediate grandparents. Always check specific country laws.

What is an ancestry visa?

An ancestry visa is a type of visa that allows individuals to live, work, and sometimes study in a country based on their ancestral heritage. Ancestry visas in the UK enable citizens born overseas in Commonwealth nations, with minimum one grandparent born in the UK, to enter the UK to work or study.
