Having citizenship from the European Union (EU) brings many benefits. In addition to being able to live in some of the best economies in the world, enjoying a high quality of life, those who hold a European passport can travel without a traditional visa to most countries around the world.
Data shows that in 2021 alone, 827,000 people acquired citizenship from one of the EU countries, an increase of nearly 14%, or 98,300 more people than in 2020. 85% of them were citizens of a non-EU country or stateless.
One of the main pathways through which foreigners become EU citizens is naturalization through residency in a specific EU country. Through this route, foreigners must reside for a certain period in that country and meet various conditions before applying for citizenship by naturalization.
Check below the requirements for naturalization by residency in each of the countries that are part of the EU:
Austria
Citizenship through naturalization is possible in Austria for foreigners who have lived in the country for at least 30 continuous years. This extremely long period, however, can be shortened to at least fifteen years if the foreign resident demonstrates successful personal and professional integration in the country and to ten years if the resident meets the following conditions:
• has sufficient financial means/stable income
• has no criminal record
• has sufficient knowledge of the German language and a positive attitude towards the Republic of Austria
Belgium
In Belgium, foreigners must be 18 years or older, reside in the country legally for an uninterrupted period of five years, in addition to proving that they are integrated into the country. This means they will need to show that they master the language, are socially integrated, and participate in the country’s economy.
Bulgaria
Bulgaria also allows non-EU citizens over 18 years old to obtain Bulgarian citizenship after living for five years with a permanent or long-term residence permit.
However, there are other conditions to obtain citizenship in Bulgaria. Candidates must prove that they have never been convicted of any crime, that they are financially stable, and that they know the Bulgarian language. The Bulgarian language exam is organized by the Ministry of Culture itself, and residents who fail cannot obtain citizenship, even if they meet all other conditions.
Croatia
In Croatia, a period of eight years of continuous legal residence is required to apply for Croatian citizenship. Foreigners aged 18 or older can apply for Croatian citizenship if they have no police record and are financially stable. They must also pass two tests, one in the Croatian language and one on culture. Renouncing previous citizenship is also mandatory.
Cyprus
Cyprus offers citizenship by naturalization for those who have legally resided in its territory for a period of seven years. The period is reduced to five if the applicant is a parent or child of a Cypriot citizen. The applicant must have a clean criminal record.
Czech Republic
The Czech Republic is on the list of EU countries that allow foreigners to obtain citizenship after just five consecutive years in the country. Every foreigner needs to meet some prerequisites to obtain Czech citizenship, including being well integrated into society and not posing a threat to the security of the state, its sovereignty, and territorial integrity.
Denmark
Foreigners in Denmark must live there for a period of nine uninterrupted years before they can apply for citizenship. Additionally, they need to prove that they are self-sufficient and that, in the five years prior to the application, they have not received any assistance from Danish authorities. They must not have any outstanding debts to public authorities. As in other countries, they must provide proof of a clean criminal record. Proficiency in the Danish language is also mandatory.
Estonia
Foreigners who have resided in Estonia for at least eight years with a residence permit can apply for citizenship in the country. Other requirements include passing an Estonian language proficiency exam, proven income, and proof of loyalty to the Estonian state.
Finland
Finnish citizenship is granted to all applicants who have resided in the country for a period of five uninterrupted years. Satisfactory oral and written skills in one of the following languages are also required: Finnish, Swedish, Finnish Sign Language, or Finnish Swedish. Knowledge of one of these languages must be proven through a certificate accepted by Finnish authorities.
France
Foreigners can apply for French residency after just five years in the country. As in other countries, you also need to prove ‘sufficient and stable resources’ to live in the country, show your integration into the French way of life, and prove that you understand, speak, and write French to a certain level.
Germany
Germany grants citizenship to foreign residents only after they have lived in its territory for a period of eight years. For those who successfully complete an integration course, this period is reduced to seven years. Sufficient proficiency in the German language, familiarity with the legal system, and adaptation to the German way of life are also required, along with a clean criminal record and the ability to support oneself financially.
Greece
People over 18 can obtain Greek citizenship after living seven consecutive years in Greece or residing legally for five years. Those married to Greek citizens, as well as nationals from other EU countries, can obtain citizenship in this country after just three years of continuous residence. Mandatory conditions also include knowledge of the Greek language, participation in political life, and harmonious integration into the economic and social life of the country.
Hungary
Eight years of continuous residence in Hungary is sufficient for a person to apply for Hungarian citizenship if other conditions are also met. Good character, a clean criminal record, and passing a basic constitutional studies test of the country are required. Those who started living in Hungary before the age of 18 can obtain citizenship after just five years, provided that other conditions are also met.
Iceland
Foreigners are entitled to Icelandic citizenship if they have legal domicile and continuous residence in Iceland for seven years. By continuous residence, Icelandic authorities mean that the foreigner must not have stayed abroad for more than 90 days in total in each 12-month period. Passing an Icelandic language test is mandatory, as well as having sufficient financial means to support oneself. Receiving financial assistance from a municipality in the last three years before the application deprives foreigners of the right to acquire Icelandic citizenship.
Ireland
Ireland requires foreigners to prove that they have legally and continuously resided in its territory for a minimum period of five years before applying for citizenship. They must have a clean criminal record, with no traffic fines, no pending criminal cases, and no ongoing investigations.
Italy
In addition to a clean criminal record and sufficient financial means, Italy requires foreigners to have lived in its territory for at least ten years before obtaining Italian citizenship. This makes Italy one of the countries with the longest residency requirement in the EU. Adopted children of an Italian citizen can obtain citizenship after seven years, while nationals from other EU countries can do so after four years.
Latvia
People aged 15 or older can acquire Latvian citizenship if they live in the country with a permanent residence permit for a period of five years.

Poland
Poland is the EU country that grants citizenship to foreigners with the shortest residency time compared to other EU members. In Poland, a foreigner can acquire nationality after just three years with a permanent residence permit, provided they have a stable source of income.

This period is reduced to seven years for those who have completed higher education in Slovenia and to three years if the applicant is married to a Slovenian citizen.
