The Three-Year Clock & How to Request Extra Time for Inburgering

Understand the 3-year integration deadline (inburgeringstermijn) and learn about the valid reasons for requesting an extension, such as illness, pregnancy, or other special circumstances.

July 17, 2025

Every person required to integrate in the Netherlands is given a set period to complete the process, known as the inburgeringstermijn. For most people, this is a three-year clock that starts ticking from the moment you are officially registered. Failing to meet this deadline can lead to fines, so understanding how it works and when you can get an extension is critical.

The Standard Three-Year Term

The standard integration period is three years. For those under the 2021 Act, this period starts on the date your Personal Integration Plan (PIP) is finalized. For those under the 2013 Act, it starts from the date you receive your official integration duty letter from DUO. You can always check your personal start and end dates in the Mijn Inburgering portal.

Valid Reasons for Requesting an Extension

DUO can grant an extension ('verlenging') if you can prove that the delay is not your fault. You typically need to apply for an extension at least 2.5 years into your term. Common valid reasons include:

  • Serious Illness: If you or a close family member (partner, parent, or child) has been ill for more than three months, preventing you from studying.
  • Pregnancy and Childbirth: Women can receive a standard 16-week extension after giving birth.
  • Alphabetisation Course: If you first needed to complete an alphabetisation course ('alfabetiseringscursus') to learn how to read and write in the Latin alphabet.
  • Family Bereavement: The death of a close family member (partner, parent, or child).
  • Other Special Circumstances: In some cases, issues with a language school or delays caused by the municipality (under the 2021 Act) can also be grounds for an extension.

How to Apply

You must apply for an extension by sending a specific form to DUO, along with official proof. For example, a medical certificate from a Dutch doctor, a birth certificate for your child, or a death certificate. The forms are available on the DUO website.

What if You Don't Get an Extension?

If you miss your deadline without a valid extension, you risk receiving a fine from DUO. Read our upcoming guide on fines and how to handle them for more information.
