Applying for Belgian citizenship: requirements, documents and help
Have you lived in Belgium for years and want to become Belgian? The Belgian citizenship requirements are strict and every piece of evidence counts. We help you check whether you are eligible and put together a complete file with you.
You usually apply for Belgian citizenship with a nationality declaration at your municipality. Which requirements apply depends on how long you have been legally resident in Belgium and on your situation.
In most cases you must show, among other things, that you have lived legally in Belgium for years, speak one of the national languages, are integrated and work or have worked. Missing evidence can lead to a negative opinion, and then you lose time and money.
Which documents do you usually need?
- Birth certificate (with a translation or multilingual form if needed)
- Proof of legal residence in Belgium for the required period
- Proof of knowledge of a national language (Dutch, French or German)
- Proof of integration, such as a diploma or a civic integration certificate
- Proof of work or self-employed activity for the required period
This is a general list. Exactly which documents you need depends on your situation and your municipality. After our first contact, you will receive a list tailored to you.
