Legal Ways to Obtain Belgian Citizenship

Belgian citizenship can be obtained through birth (in certain cases), descent, adoption, restoration, naturalization, and exceptional merit. For foreign nationals, the main requirement for acquiring this status is a period of legal residence in the country. In addition, applicants are generally required to demonstrate knowledge of one of Belgium’s three official languages, social integration, and an economic contribution to the country’s development, as established by the Belgian Nationality Code.

The naturalization process begins with obtaining a Type D entry visa, followed by temporary residence and a residence permit with unlimited validity. An individual may apply for Belgian citizenship after 5 years of continuous legal residence within the country’s jurisdiction. The benefits of holding a Belgian passport include visa-free travel to 175 countries, full access to the labor market, eligibility for various benefits and social assistance programs, and the right to reside permanently in other European Union member states.

Benefits of a Belgian Passport

A Belgian passport provides its holders with a wide range of advantages within the country, including:

• permanent residence without restrictions related to the length of stay abroad;
• access to employment in any sector and the right to start a business without obtaining additional permits;
• access to education at reduced tuition rates;
• the ability to use banking services with more favorable lending conditions than those generally available to foreign nationals;
• access to healthcare through Belgium’s high-quality medical system under the applicable insurance scheme;
• eligibility for the full range of social benefits and government support programs;
• the right to participate in political elections.

Outside the Kingdom of Belgium, Belgian passport holders are entitled to:

• visa-free or simplified travel to approximately 175 countries, including the United States and Canada;
• the right to reside in other European Union member states through a straightforward registration procedure;
• access to education, employment, and business opportunities across the European market;
• emergency medical treatment in healthcare facilities throughout the European Union;
• participation in elections to the institutions of the European Union.

Grounds for Obtaining Belgian Citizenship

Each pathway to Belgian citizenship has its own specific requirements. Children born in Belgium automatically acquire nationality if at least one parent is a citizen. If a child is born abroad to a Belgian family, they may obtain this status provided that a relevant declaration is submitted within the first five years of their life, or before the age of 18 if they do not hold another nationality or if their parent was also born in Belgium. Minor children adopted by citizens are likewise eligible to acquire Belgian nationality. If the adopted child was born outside the country, the application must be submitted within five years from the date the adoption was granted, unless it can be demonstrated that the child does not possess another nationality or that the adoptive parent was born in Belgium. Foundlings discovered within the territory of Belgium are considered citizens if their origin cannot be established.

Children born in Belgium to foreign parents may also qualify for Belgian citizenship if their mother and/or father was born in Belgium and has lived in the country for at least five of the previous ten years. Another possibility exists where the child has lived in Belgium since birth, the parents submit the relevant declaration before the child reaches the age of 12, and the parents themselves have legally resided in the country for at least ten years, with at least one of them holding permanent residence status.

Individuals who have reached the age of 18 and can demonstrate exceptional merits in favor of the Belgian state may obtain citizenship through an accelerated procedure. Adult applicants who previously held Belgian nationality and lost it for reasons other than deprivation may restore their status, provided they have resided in Belgium for at least 12 months prior to submitting the application.

For foreign nationals, naturalization remains the primary route to Belgian citizenship. Applicants are generally required to live in Belgium legally and continuously for at least five years. They must demonstrate knowledge of one of the country’s three official languages and prove integration into society, for example through participation in integration programs or courses. Those applying through the standard naturalization procedure must also show economic participation, such as having worked as an employee for at least 486 days during the previous five years or having paid taxes as a self-employed person.

Spouses of Belgian citizens may satisfy the economic participation requirement by proving that they have lived together in Belgium for at least three years or have a common minor child. Persons with disabilities are generally required only to complete five years of residence in the country. There is also a pathway based on ten years of residence in Belgium combined with language proficiency and active participation in community life, in which case some of the other requirements do not apply.

To begin the naturalization process, an applicant must first obtain legal residence in Belgium on one of the available grounds.

Employment

Foreign nationals who intend to engage in gainful employment in Belgium as salaried workers are required to obtain a work permit. Responsibility for issuing such permits lies with the regional authorities. The employer must submit an application for the permit, and once it has been approved, the employee may begin the visa application process.

Applicants for employment-based residence are generally required to demonstrate a clean criminal record, sufficient financial means to support themselves, and valid health insurance coverage. Depending on the profession and field of activity, such as research, domestic assistance, internships, seasonal employment, or other categories, additional requirements may apply for obtaining a work permit, visa, and subsequently a residence permit.

Entrepreneurship

Foreign nationals wishing to start or operate a business in Belgium are required to obtain a professional card for self-employment. Applications for this permit can be submitted in several ways: online through the WSE platform, via the electronic service desk of the Department of Work and Social Economy (DWSE) while residing in Belgium, or through a Belgian consulate abroad.

Applicants seeking self-employed status must demonstrate appropriate qualifications, sufficient financial resources, and provide a viable business plan that outlines the prospects and sustainability of the proposed business activity.

Family Reunification

Family members of a Belgian citizen or a foreign national who legally resides in Belgium may join their relative in the country. The possibility of relocating to the kingdom is available to spouses, minor children of the sponsoring person, and, in certain cases, parents and partners.

The sponsor residing in Belgium must demonstrate that the conditions for family reunification have been met. These requirements depend on factors such as citizenship, age, family relationship, and the legal status of the sponsoring person. The validity period of the residence permit and the processing time for the application vary depending on whether the family member is joining a Belgian citizen or a legal resident of the country.

Education

Foreign nationals who have been admitted to a full-time program at a Belgian higher education institution that is state-run or officially recognized by the authorities may apply for a Belgian residence permit. Participation in exchange programs does not provide grounds for obtaining a residence permit or beginning the naturalization process.

After completing their studies, graduates may apply for a residence permit to search for employment or start their own business and continue residing in the country. Applicants for student residence status must demonstrate that they have sufficient financial resources to support themselves throughout the period of their studies.

How to Obtain Belgian Citizenship: Step-by-Step Procedure

To become a Belgian citizen, a foreign national must reside in the country for at least 5 years. The processing time for a citizenship application is approximately 5–6 months, bringing the overall duration of the process to around five and a half years. There is no publicly available information regarding the possibility of checking the status of an application online through an official government website.

The main stages of the naturalization process include:

Required Documents: Complete List

The application dossier must be submitted in full and contain accurate, truthful information about the applicant. A birth certificate must be provided as a full copy together with a translation into one of Belgium’s official languages and accompanied by legalization or an apostille where required. Identity documents should be submitted as photocopies of both sides.

Application Form

The application is completed using an official form provided directly by the relevant authority when the dossier is submitted. An authorized officer will provide the form and general guidance on how to complete it and, if necessary, answer any questions the applicant may have.

Documents for Citizenship

The standard citizenship application dossier includes:

• birth certificate;
• passport;
• proof of social integration and language proficiency, such as an educational diploma or a certificate confirming completion of a recognized integration course;
• proof of economic participation, for example individual records showing the number of days worked or social security contributions paid.

Applicants applying as the spouse of a Belgian citizen must additionally provide a marriage certificate. Persons with disabilities are required to submit proof of their status, while applicants who have lived in Belgium for at least 10 years must provide a written declaration confirming their participation in community life.

Documents for Obtaining a Passport

To apply for Belgian identity and passport documents through the competent authorities, the applicant must provide a valid identity document as well as any previous identity document or passport, if available. Photographs are not required, as they are taken directly at the registration desk during the application process.

Cost of Obtaining Belgian Citizenship

Purchasing a Belgian passport through investment is not possible. Belgium does not offer citizenship-by-investment programs that allow foreign nationals to acquire status in exchange for a financial contribution. Therefore, for most applicants from non-EU countries, the only available route is the standard naturalization procedure. The government fee for submitting an application is approximately EUR 150. Applicants who are restoring previously held Belgian nationality are generally exempt from this fee.

After becoming a Belgian citizen, individuals may apply for national identity and travel documents. The cost of obtaining a Belgian passport varies depending on the municipality, processing time, and the applicant’s age, but typically ranges from EUR 65 to 150. A Belgian electronic identity card (eID) generally costs between EUR 20 and 35, depending on the local authority issuing the document.

Additional expenses should also be taken into account. These include document preparation, certified translations, apostille or legalization services, which usually start at EUR 20–30 per page depending on the country of issuance and the service provider.

Applicants pursuing the naturalization route must also consider the costs associated with long-term residence in Belgium, including accommodation, healthcare, food, transportation, and other living expenses. Prior to obtaining citizenship, foreign nationals are generally required to secure the appropriate visa and residence permit. Visa fees usually range from EUR 180 to 250, while the cost of obtaining or renewing a Belgian residence card is typically EUR 25–150, depending on the type of permit and local administrative charges.

As immigration fees and administrative charges may vary between municipalities and are subject to periodic changes, applicants should verify the latest rates with the relevant Belgian authorities before submitting their applications.

Refusal of Belgian Citizenship

Belgian authorities may reject an application if the applicant fails to meet one or more of the requirements established by law. There is also a risk of refusal if the applicant submits an incomplete dossier or provides inaccurate or false personal information. Applicants are reviewed by the competent authorities to determine whether they may pose a threat to national security or public order. If the applicant’s background contains facts related to such violations, or if there are other serious concerns, the application may be refused.

The responsible authority notifies the applicant of the refusal by registered letter, indicating the reasons for the negative decision. After receiving the notification, the applicant has 15 days to file an appeal with the family court. To avoid a negative decision and unnecessary time spent on appeals or repeated applications, it is important to approach the preparation of the dossier, the study of legal provisions, and compliance with all requirements as carefully as possible. If necessary, applicants may seek professional assistance, which can help reduce existing risks.

How to Obtain Belgian Passport

Citizens of the Kingdom of Belgium receive two identity documents: a national identity card in the form of a plastic ID card and an international passport, which is issued as a booklet with a dark red cover and the standard design used by European Union member states.

To obtain both identity documents, applicants must:

• receive confirmation of the acquisition of Belgian citizenship and, in the case of the ID card, have permanent residence in Belgium;
• prepare an application and the required supporting documents;
• schedule an appointment at the administrative center in Brussels or a municipal office in another city and visit the authority on the designated date and time;
• collect the document from the registration desk without the need for a prior appointment.

A Belgian passport can be issued within 8–10 working days under the standard procedure. Expedited processing is available within 1–2 days, while an ultra-fast procedure allows issuance within approximately 4.5 hours. The passport must be collected within 3 months of the application date; otherwise, it will be destroyed and the applicant will need to repeat the procedure.

A Belgian national identity card is generally issued within 2–3 weeks under the standard procedure. Under the expedited procedure, the document may be available the next day if the application is submitted before 3:00 p.m.

Dual Citizenship and a Second Belgian Passport

Belgian nationals are allowed to hold more than one passport, although possessing multiple legal affiliations may result in different rights and obligations depending on the countries involved. If the relevant states have concluded a bilateral agreement on this matter, the situation is considered dual citizenship. In such cases, the individual is recognized by both jurisdictions, and while residing in one of them, is generally subject only to the rights and obligations established by that country’s legislation.

If no such agreement exists and the laws of the countries concerned do not expressly prohibit multiple nationalities, an applicant may retain their existing status and acquire Belgian nationality in addition to it. In this situation, each country recognizes the individual exclusively as its own national, and the person may be subject to the rights and obligations imposed by both jurisdictions.

Holding a second passport provides access to the full range of associated rights and privileges without imposing additional restrictions. Individuals are free to use and benefit from all legally held travel and identity documents in accordance with the laws of the respective countries.

Is It Worth Obtaining a Belgian Passport Through Naturalization?

Naturalization is the most accessible way for foreign nationals to obtain Belgian citizenship. At the same time, the procedure is relatively lengthy and requires applicants to be prepared for a multi-stage process involving numerous administrative formalities and the costs associated with long-term residence in the country. For this reason, it may be worth considering alternative options that can provide access to the same rights and privileges within a shorter period of time.

Several EU countries offer repatriation programs that allow eligible applicants to obtain a passport in as little as 12 months. Since Belgium is a member of the European Union, a citizen of any other EU country has the right to settle permanently in the kingdom and enjoy rights comparable to those of Belgian nationals. These pathways to EU citizenship generally do not require applicants to spend several years living in the selected country, and in many cases knowledge of the local language is not mandatory.

Nationals of non-EU countries may have opportunities to participate in such programs depending on their family history and individual circumstances. Regardless of the chosen immigration pathway, assistance from Migronium specialists can be beneficial. Professional guidance allows applicants to objectively assess the advantages and disadvantages of different options, verify their eligibility for a second passport, and explore available routes, including accelerated procedures where applicable.

Reviews from migrants who have successfully obtained citizenship abroad confirm that the process is often much more efficient and straightforward when carried out with professional assistance. Applicants frequently note that understanding foreign legislation can be challenging, especially given the regular changes to immigration laws and procedures. Legal specialists, on the other hand, stay up to date with current regulations and work in accordance with the latest legal requirements.
