Becoming a Belgian

You can automatically obtain Belgian nationality or you can obtain it by taking steps yourself. This is usually done by contacting the city.


How to request Belgian nationality?

    You can request Belgian nationality by submitting a nationality declaration to the city.

    1. Assemble the documents
    More information about the required documents can be found on the website of the FPS Justice.

    Need advice?
    You may scan and forward documents that you have already assembled. In this way we can verify which documents you may still require.
