Some countries offer special ways to get citizenship if you can prove your family came from that country. These are called citizenship by descent or ancestry-based paths. For many immigrants and descendants, these routes can be an accessible way to reconnect with family history and gain a second passport.
Special descent paths are different from ordinary naturalization. In normal immigration systems, people often need to live in the country for many years, learn the language, and pass other tests. Descent-based routes can skip some of those steps.
Why These Countries Stand Out
These countries are special because they go beyond the usual immigration rules. Instead of focusing only on where a person lives now, they look at ancestry, ethnicity, or historical family ties. That means people may qualify even if they were born in another country.
Bulgaria
Bulgaria has one of the more flexible descent-based citizenship routes in Europe, especially for applicants who can prove Bulgarian ethnic origin. No language exam is required for the descent route, and applicants may qualify through three main categories: a person of Bulgarian origin, a person adopted by a Bulgarian citizen under full adoption, or a person whose parent is a Bulgarian citizen or died as a Bulgarian citizen.
For ethnicity-based applications, the path can extend up to the third generation, provided the applicant can establish the family link through official documentation. Bulgarian law also requires documents showing the names of the ascendant and the family relationship with the applicant. In practice, the process is often described as faster than ordinary naturalization, with some applications taking around 9 months.
Croatia
Croatia is special because it allows citizenship through descent without a strict generational limit. Applicants can go back as many generations as needed, as long as they can prove the chain of descent and the ancestor’s emigration abroad. For many people, Croatia is special because it shows that old family ties can still matter, even when the connection is several generations away.
A key limitation is timing: the ancestor must have left Croatia before October 8, 1991. Other disqualifications include cases where the ancestor moved to another Yugoslav republic, emigrated after that date, or returned to Croatia after emigrating.
African Descent Paths
A growing number of African countries are creating special paths for people of African descent. These routes are often based on history, return, and family connection to the African diaspora. They can be especially meaningful for descendants of people who were taken away through slavery, colonialism, or forced migration.
One of the most important examples is Benin. In 2025, Benin passed a law recognizing historical ties with people of African descent. Under this law, people of African descent can request citizenship if they are over 18, are not citizens of another African country, and can prove descent through civil records or a state-recognized DNA test.
This is important because it gives people more than one way to show their family link. For some families, old records may be missing. In those cases, DNA testing may help support the claim. Benin’s approach is a strong example of how some countries are adapting to the needs of diaspora communities.
Other African countries have also taken steps in this direction. Liberia was one of the first African countries to offer descendants of enslaved Africans from the United States a path to return. Ghana created the Right of Abode law in 2000, giving African descendants and diaspora members the right to live and work there. Sierra Leone has also developed descent-based programs for people who can prove ancestral ties.
These programs are not all the same. Some give full citizenship. Others give the right to live and work in the country. Some are newer and still developing. But they all share a common idea: family history and diaspora ties should matter.
Why It Matters
What makes these countries special is that they see ancestry as a real legal connection. They also show that countries are thinking in new ways about heritage and belonging. Some are making old nationality laws more flexible. Others are creating new paths for diaspora communities that were once left out.
For many immigrants and descendants, that can mean more than a passport. It can mean identity, belonging, and a way back to family history.
