Two ways to become a Dutch citizen
There are two main paths to Dutch citizenship: naturalisation (naturalisatie) and option (optie). Most immigrants will use the naturalisation route. The option route is available in specific cases — for example, if you were born to a Dutch parent or lived in the Netherlands as a child.
This guide focuses on naturalisation — the most common path for people who have moved to the Netherlands as adults.
Requirements for Dutch naturalisation
To apply for Dutch naturalisation, you generally need to meet all of the following conditions:
1. Residence in the Netherlands for 5 years
You must have held a valid residence permit and lived in the Netherlands continuously for at least 5 years. Certain gaps or absences can reset or pause this period. Partners of Dutch citizens may qualify after 3 years.
2. Permanent residence permit (verblijfsvergunning voor onbepaalde tijd)
You need either a permanent residence permit or a long-term EU resident status. A regular temporary residence permit is not sufficient for naturalisation.
3. Pass the inburgering exam (or have an equivalent diploma)
This is where the KNM exam becomes directly relevant. The inburgering exam — of which the KNM exam is a key part — is required for most naturalisation applicants. It proves that you understand Dutch society and speak Dutch at a sufficient level (B1).
What is the KNM exam? The KNM exam (Kennis van de Nederlandse Maatschappij) tests your knowledge of how Dutch society works — employment, housing, healthcare, government, and more. It has 45 multiple-choice questions and you have 40 minutes. Read the full KNM exam guide here.
4. Not have a criminal record
You must not have been convicted of a crime in the Netherlands or abroad during the period relevant to your application. Minor traffic violations typically do not count, but more serious offences can disqualify you.
5. Renounce your current nationality (in most cases)
The Netherlands generally requires you to give up your current citizenship when you become Dutch. However, there are many exceptions — for example, if you are a citizen of a country that does not allow renunciation, or if you would lose significant rights (such as inheritance or property rights in your home country). The IND assesses this case by case.
The naturalisation process step by step
Check your eligibility
Use the IND's online tool at ind.nl to verify that you meet the residence, permit, and inburgering requirements before you apply.
Complete your inburgering (if not already done)
If you still need to pass the inburgering exam, start your preparation now. The KNM exam is one of the hardest components — begin with topic-specific practice and work up to full mock exams.
Submit your application at the municipality
You apply for naturalisation at your local gemeente (municipality). Bring all required documents: passport, residence permit, proof of inburgering, income statements, and a recent Certificate of Good Conduct (VOG).
IND review (up to 12 months)
The IND (Immigration and Naturalisation Service) reviews your application. Processing typically takes 6–12 months. You may be asked for additional documents during this time.
Naturalisation ceremony
If your application is approved, you attend a naturalisation ceremony at your municipality. This is a formal event where you take the civic oath or declaration (naturalisatieceremonie). After the ceremony, you are Dutch.
How long does it take to become a Dutch citizen?
| Minimum residence period | 5 years (3 years for partners of Dutch citizens) |
| Inburgering preparation | 2–12 months depending on starting level |
| Application processing | 6–12 months at the IND |
| Total from arrival to citizenship | Typically 6–8 years minimum |
The role of the KNM exam in naturalisation
The inburgering exam — including the KNM component — is a prerequisite for most naturalisation applications. This means that passing the KNM exam is one of the concrete steps you need to take on the path to Dutch citizenship.
The KNM exam tests exactly the knowledge that the Dutch government wants new citizens to have: how employment works, how the healthcare system is organised, what your rights and duties are, and how Dutch democracy functions.

Frequently asked questions
Can I have dual citizenship (Dutch + my current nationality)?
Generally no — the Netherlands requires you to renounce your current citizenship. But there are many exceptions. Check the IND website or speak to a lawyer for your specific situation.
Do I need to speak Dutch to become a Dutch citizen?
Yes. The inburgering exam requires you to demonstrate Dutch language skills at B1 level (speaking, reading, writing, listening). The KNM exam is in Dutch, so some language knowledge is also required there.
What if I have lived in the Netherlands for less than 5 years?
You cannot yet apply for naturalisation, but you can use this time to complete your inburgering exam, including the KNM. Being prepared early puts you in the best position when you reach the 5-year mark.
Is there an English version of the naturalisation application?
The IND website has information in English at ind.nl/en. The actual application and exam are in Dutch.
