EU Countries offering citizenship by ancesteral descent up to 3 Generations


Recent amendments to Bulgaria's citizenship laws allow individuals to apply for citizenship by ancestry up to the third generation. If your great-grandparents, grandparents, or parents were Bulgarian citizens, you are eligible to apply for Bulgarian citizenship.

The application process for citizenship by descent from Bulgaria has also become more accessible. In addition to submitting your application, you must provide documentation proving that your ancestors were Bulgarian nationals. A response to your application may take up to 24 months.


If one of your ancestors, be it a parent, grandparent, or great-grandparent, holds Croatian citizenship, you may be eligible to acquire it by descent. However, you cannot obtain citizenship by descent if your ancestor left Croatia before 8 October 1991 and moved to another country in the former Yugoslavia.

If you were born to Croatian parents outside of Croatia and they did not register your birth, you have until the age of 21 to register in the civil registration if you want to apply for Croatian citizenship.


Greece is another European Union country that allows citizenship by descent up to the third generation.

If you meet any of the following criteria, you may be eligible for Greek citizenship through your ancestry:

  • If your parents were married and you were born before July 16, 1982, and your father was a Greek citizen but your mother was not.

  • If you were born after July 16, 1982, and your father was a Greek citizen regardless of whether he was married to your mother, but your mother was not a citizen of Greece.

  • If your mother was a Greek citizen, and your father was a foreigner, and you were born before or after August 5, 1984, regardless of whether they were married.

  • If you have a Greek grandmother or great-grandparent in your lineage.


Citizenship by descent up to the third generation is permitted in Ireland, which is one of the EU nations that allows it. You are eligible to apply for Irish citizenship if you meet any of the following requirements:

  • You were born to at least one Irish parent.

  • You were born in Ireland to non-Irish parents who had resided in the country for at least four years.

  • You were born outside of Ireland to Irish parents.

  • At least one of your grandparents was an Irish citizen, even though you were born outside of Ireland.

  • Your parents, grandparents, and great-grandparents were born outside of Ireland, but your great-grandparents were born in Ireland.

  • Your parents must be included in the Foreign Births Register.

  • To apply for citizenship by descent in Ireland, you must first register your birth with the Foreign Births Register. After that, you may proceed with the rest of the application process.


Italy allows citizenship by descent up to the 3rd generation or beyond, similar to Hungary. However, the ancestry search can only be traced back to 1861, the year when Italy was officially united.

Moreover, Italy only recognized maternal citizenship in 1948.

If your parents acquired citizenship of another country, there are additional regulations to consider. For example, if your parents migrated from Italy to the United States and you were born there, but they became US citizens after your birth between July 1, 1912, and August 15, 1992, you would still be eligible for Italian citizenship.


To be eligible for Latvian citizenship by descent under Latvian law, the following criteria must be satisfied:

  • One of your parents, grandparents, or great-grandparents was a citizen of Latvia before June 17, 1940.

  • You have a parent, grandparent, or great-grandparent who was a Latvian citizen but was forced to leave the country between June 17, 1940, and March 4, 1990, due to the occupation by Nazi Germany and the USSR.

  • In Latvia, citizenship by descent can be obtained up to the third generation, or earlier if you can demonstrate that your ancestors were Latvian citizens.


Citizenship by descent in Luxembourg can be obtained in one of three ways:

  • Reclaiming citizenship: If you have a direct maternal or paternal ancestor who was a Luxembourg citizen on January 1, 1990, you are eligible to reclaim your citizenship.

  • Ancestral citizenship: If a direct male ancestor (starting with your father, grandfather, great-grandfather, and so on) was born in Luxembourg before 1940, you can petition for citizenship. Alternatively, if your mother's lineage can be traced through a male ancestor to a person who resided in Luxembourg, and you were born on January 1st, 1969, you are also eligible for this option.

  • Applying for citizenship: If your parent or grandmother is a Luxembourg citizen but was unable to pass on their nationality to you, you may be eligible for citizenship by choice. This option is available if you were not permitted to hold dual citizenship under the nationality laws of another country.

Luxembourg allows citizenship by descent up to the third generation or earlier in certain circumstances. However, it's important to note that the deadline for submitting a certificate demonstrating your ancestor resided in Luxembourg to complete the first stage of the "reclaim" procedure passed in 2018. If you missed the deadline for the first option, you should consider the other citizenship options available. If you completed the first step, you have until December 2022 to sign your declaration of citizenship.


To be eligible for Polish citizenship through ancestry, you need to have an ancestor who was born in Poland and lived there after 1920, up to the third generation or earlier.

If your ancestor left Poland before 1920, you can still apply for citizenship if you can provide evidence that they were listed as citizens in Polish, Prussian, Russian, or Austro-Hungarian records and that they lived in Poland at the time of your birth. However, if your ancestor acquired a new citizenship before 1951, they lost their Polish nationality and could not pass it on to you.
