Belgium is a member of the Schengen Agreement.
- There are normally no border controls between the countries that have signed and implemented the treaty. This includes most countries of the European Union and a few other countries.
- Before boarding an international flight or ship, there is usually an identity check. Sometimes there are temporary checks at land borders.
- Similarly, a visa issued for a member of the Schengen area is valid in all other countries that have signed and implemented the treaty.
Nationals of the above-mentioned countries are allowed to work in Belgium without a visa or other authorisation for the duration of their 90-day stay. However, this possibility to work without a visa does not necessarily extend to other countries in the Schengen area.
