Citizenship by Naturalization: Unlocking the Process

Citizenship by naturalization is the process of becoming a citizen of a foreign country by meeting certain legal requirements. These requirements can include things like living in the country for a certain number of years, speaking the language, and understanding the country’s culture, but exact rules vary by country.

Naturalization can occur through long-term residency, marriage, descent, or investment. It offers many benefits, such as finding a home in another country and enjoying the privileges of your new citizenship. Other countries may have different naturalization processes, but the core steps remain similar for citizenship and naturalization, allowing individuals and their family members to gain new citizenship.

What is citizenship by naturalization?

Citizenship by naturalization is the legal process by which a non-citizen of a country willingly acquires citizenship of that country after meeting specific requirements set by that nation’s laws.  

It allows individuals who have lived in a country for a certain period, often as permanent residents, to become full citizens, gaining rights like voting, holding public office, and obtaining a passport. 

Unlike citizenship by birth or descent, naturalization is based on fulfilling residency, language, and civic obligations and demonstrating loyalty to the country. 

How to Obtain Citizenship by Naturalization

There are many routes to obtaining citizenship through naturalization. Many countries offer naturalization services with pathways that involve meeting specific residency, legal, or social criteria over time.

Here are the different ways to qualify for naturalization:

Residency-based naturalization

One of the most common ways to become a naturalized citizen is to live in a country for several years. Many countries require individuals to live in the country for a certain time as permanent residents before they can apply for citizenship. The residency requirement typically ranges from three to ten years, depending on the country.

Marriage to a citizen

Another fast way to get citizenship is through naturalization through marriage. Spouses of citizens can often apply for citizenship by marriage, which generally requires a shorter residency period, usually two to five years, and proof of a genuine relationship.

Descent or family connection

Some countries offer citizenship to individuals who can prove ancestry or family ties to a country’s citizens, even if they were born abroad. For instance,  Ireland allows children born with Irish ancestry or descent to claim citizenship through the Foreign Births Register. Italy also offers citizenship by descent if you have an Italian ancestor, regardless of how many generations back, as long as certain legal conditions are met.

Military service

Several countries offer expedited citizenship to foreign nationals who serve in their military. This is common in countries like the United States, where non-citizens can become citizens more quickly by serving in the armed forces.

Economic investment

Another effective and fast path to becoming a naturalized citizen is citizenship through investment programs. Some countries grant citizenship to individuals who make significant financial investments, such as in real estate or government bonds. Countries such as Turkey, Malta, and St. Kitts & Nevis offer this option.

General Requirements for Citizenship by Naturalization

Requirements for obtaining citizenship through naturalization vary from country to country, but they generally revolve around a set of standard requirements you must meet. However, certain circumstances may alter the process depending on the government. 

Here are the critical requirements considered by immigration services that grant citizenship through naturalization:

Residency requirement

Most countries require a period of continuous residency before applying for naturalization. The duration varies by country, ranging from a few years to over a decade. For example, in the U.S., applicants must be green card holders for at least five years and maintain continuous residence, with physical presence for half of that time.

Good moral character

Maintaining good moral character is an essential criterion for naturalization. It implies that the applicant or naturalized citizen should have a clean criminal record without criminal convictions and sound character. Countries that grant citizenship may need to conduct background checks and scrutinize applicants’ and naturalized citizens’ conduct, behavior, and reputation during residency to assess their moral character. 

The U.S. is another country that requires good moral character as a specific requirement for the naturalization process. Applicants cannot be involved in minor offenses like DUIs or failure to pay child support, as this can affect their eligibility.

Language proficiency

Language proficiency is often a requirement to demonstrate integration and the ability to communicate effectively in the host country. Many countries require applicants to pass language tests to ensure a basic understanding of the official language(s). This proficiency requirement may involve written, spoken, and comprehension skills.

For example, the United Kingdom requires passing an English test and demonstrating knowledge of life in the UK during the naturalization process, as do Sweden and the Netherlands, which require passing the Civic Integration Examination with a language proficiency assessment.

Knowledge of the country’s history

To ensure a meaningful connection and integration into the host country, applicants may be required to demonstrate knowledge of its history, culture, and institutions. This knowledge can be assessed through citizenship tests or interviews, where applicants may be asked questions about the country’s political system, geography, customs, and traditions.

Dual citizenship considerations

Some countries allow dual citizenship, while others may require you to renounce your original citizenship before becoming a naturalized citizen. For instance, countries such as the United Kingdom, Mexico, and Italy recognize multiple citizenship and dual nationality, allowing individuals to acquire passports without renouncing their existing citizenship.

Special considerations for naturalization

Application Process for Citizenship by Naturalization

By the time the process reaches the application stage, it means thorough research has been conducted on the immigration laws and regulations for citizenship by naturalization in the country where the applicant wishes to live.

The application process for obtaining citizenship by naturalization differs in many countries. Many nations follow a general step-by-step process, but some may require additional requirements. 

Here is a typical step-by-step process for obtaining citizenship by naturalization. 

1. Ensure eligibility

The first step for naturalization applicants is to confirm that they meet the basic requirements, such as legal residency for a set number of years, a clean criminal record, and financial stability.

2. Submit naturalization application

Complete the application form provided by the relevant government body (e.g., immigration or citizenship office) and pay the required fees.

3. Provide supporting documents

Another important step that may determine the processing time is submitting necessary and correct documents, which may include: 

• Proof of residency status,
• Identification,
• Tax records,
• Other documents to demonstrate integration (e.g., employment or community involvement).

4. Pass language and knowledge tests

A step to prove integration in society is to take a test to demonstrate proficiency in the country’s official language and pass a civics test covering the country’s history, government, and laws.

5. Attend an interview

Some countries require an in-person interview to assess your understanding of the country’s values, laws, and reasons for seeking citizenship. For example, countries like France and Australia require interviews with local authorities to assess integration, language skills, and knowledge of the countries’ society.

6. Undergo background checks

Authorities will conduct a background check to verify your criminal record, financial history, and overall character to ensure you meet the good moral character requirement.

7. Wait for decision

After completing all the steps, wait for the decision on your application. Depending on the country’s processing times, this may take several months.

8. Take the oath of allegiance

Once at this step, the process is coming to an end. If approved, you will be invited to take an oath of allegiance, formally pledging loyalty to the country and agreeing to abide by its laws and values.

9. Receive citizenship certificate

After taking the oath, you will receive your citizenship certificate, officially confirming your status as a naturalized citizen.

Benefits of Citizenship by Naturalization

Full legal rights

Naturalized citizens gain the same rights as native-born citizens, such as voting in elections, running for public office (except for some high-level positions in certain countries), and accessing government benefits and protections.

Secure residency

Citizenship provides permanent residency security, which eliminates the risk of deportation or visa renewals. You can freely live, work, and study in your chosen country without restrictions.

Global mobility

Many countries grant naturalized citizens access to powerful passports, offering visa-free or visa-on-arrival travel to numerous countries worldwide.

Family reunification

Citizenship often allows you to sponsor family members, such as spouses, children, or parents, for residency or citizenship in your new country.

Access to benefits

As a citizen, you can access public services like healthcare, education, and welfare benefits. Several countries also have social security systems exclusively for citizens.

Economic Opportunities

Naturalized citizens can own property, open businesses, and access certain jobs that are restricted to citizens. This can improve financial stability and career growth.

Inheritance and tax benefits

Some countries offer simplified inheritance laws or tax benefits for citizens, protecting your assets and reducing financial burdens.
