Your Introduction to Citizenship by Descent

What is Citizenship by Descent

Citizenship is a basic right that's existed for millennia - the very concept dates back to Ancient Greece. It provides those that hold it the right to be active participants in their community, through owning property, contributing economically, and being involved in political and administrative affairs - whether by running directly or merely voting in the process.

For centuries, people have moved around the world, establishing new roots far and wide. Citizenship by Descent (also known as Citizenship by Ancestry) provides the opportunity to return to those roots. It's a process by which individuals can gain the citizenship of their ancestors.

In the case of countries with jure sanguinis ('by right of blood'), such as Italy, it is granted to individuals provided they can prove their bloodline traces back to the country they're applying to become a citizen of. This could come via parents, grandparents or in some cases, great-grandparents.

Which Countries Give Citizenship by Descent?

There are many countries that offer citizenship by descent. However, it's important to consider that the rules and requirements can differ significantly depending on the country you're looking to become a citizen of.

For example, some countries will allow individuals to trace back as far as three (great-grandparents). Others have stricter regulations in place, only allowing an individual to go back a single generation (parents).

It's also important to consider that some countries stipulate that applicants renounce their original citizenship to become a citizen.

How to Get Citizenship by Descent?

You need to be able to provide evidence that demonstrates your lineage to the ancestor whose citizenship you're looking to obtain. Depending on the country in which you're applying to become a citizen, this will require you to provide birth certificates, passports, marriage certificates and address registers - essentially anything that can legally support your claim.

Italy

Italy is exceptionally unique in that there are no limits to how far removed you can be from your last Italian-born paternal ancestor to claim your Italian citizenship by descent. It's passed down through generations by way of jure sanguinis ('by right of blood'). It can also be claimed by those born after January 1, 1948, through the maternal ancestral line. You don't need to have been born in Italy or speak Italian to be eligible  – a single qualifying ancestor is all that's needed. Speak to our advisors to learn about claiming Italian citizenship by descent today.
