Belgium
Belgium is an EU and Schengen member state with a federal structure in which immigration is split between federal competence (residence, the Immigration Office/Office des Etrangers, nationality) and regional competence (the work-authorisation component of the single permit, handled by Flanders, Wallonia and the Brussels-Capital Region). Most third-country nationals who want to work and reside for more than 90 days apply through the 'single permit' (combined work and residence permit), with the employer initiating the file in the relevant Region. Salary thresholds for highly qualified work and the EU Blue Card differ by region and are indexed annually.
