Hiring foreign employees in Belgium means navigating a complex web of employment law, immigration procedures, and multilingual administration. Belgium has three official languages, and the relevant authorities in Brussels, Flanders, and Wallonia each operate in different languages. Finding a lawyer who speaks French, Dutch, and English is not a luxury; it is a practical necessity for any growing company that recruits international talent. This guide explains why trilingual legal support matters, how the Belgian single permit works, and where to find the right employment lawyer in Brussels.
Why a Trilingual Lawyer Matters in Belgium
Belgium is a federal state with three language communities: French, Dutch, and German. Administrative procedures for work permits are handled at the regional level, and each region communicates in its own language. The Brussels-Capital Region is officially bilingual (French and Dutch), Flanders uses Dutch, and Wallonia uses French.
When your company hires a non-European employee, you may need to interact with authorities in multiple languages depending on where the employee will work. A trilingual lawyer who speaks French, Dutch, and English can handle filings in every region while communicating seamlessly with your international hires.
Tine Avocat is a Brussels-based employment law firm that operates in all three languages. The firm's website is available in French, Dutch, and English, reflecting the daily working reality of the practice.
Understanding the Belgian Single Permit
The single permit is a residence permit granted in connection to employment. It combines both a work authorization (handled at the regional level) and a residence authorization (handled by the federal Immigration Office). Since January 3, 2019, any non-European citizen who wants to stay and work more than 90 days in Belgium must hold a single permit.
The employer must submit the application to the competent region based on the employee's principal place of work. Both the region and the Immigration Office examine the request jointly. Once deemed admissible, both authorities have up to four months to issue a decision.
Recent Changes: May 2026 Digital Portal
Since May 4, 2026, all applications for work permits for non-European nationals in the Brussels-Capital Region must be submitted through the federal One-Stop counter digital portal. PDF forms and email submissions are no longer accepted. A lawyer experienced with the new platform can prevent costly filing errors.
Processing Timeline
On average, a single permit application takes between 3 and 4 months from submission to decision. After approval, the employee applies for a Type D visa at the Belgian consulate, which takes an additional 5 to 10 business days. Registration at the local commune must happen within 8 days of arrival.
EU Blue Card and Highly Qualified Workers
The EU Blue Card is a work and residence permit for highly skilled non-EU workers who meet specific education and salary criteria. In Flanders, the gross annual salary threshold for highly qualified workers in 2025 was set at 48,912 euros (80% for workers under 30). The Blue Card offers faster processing and intra-EU mobility advantages.
An employment lawyer helps determine whether the Blue Card or the standard single permit is the better route for your specific hire. This decision depends on the employee's qualifications, salary level, and your company's long-term mobility plans. Learn more about the practice areas covered by Tine Avocat.
Key Employer Obligations When Hiring Abroad
Belgian employers must comply with several obligations beyond the work permit itself. A Dimona declaration is required for employees subject to Belgian social security. For posted workers, a Limosa declaration must also be filed. Failure to comply exposes the employer to sanctions and potential criminal liability.
Employment contracts for foreign workers must comply with Belgian labor law, including language requirements. In the Brussels-Capital Region, contracts can be drafted in French or Dutch. In Flanders, the employment contract must be in Dutch. An employment lawyer ensures your contracts meet all current legal requirements.
Upcoming EU Directive Changes
Directive (EU) 2024/1233, adopted on April 24, 2024, will soon require Belgium to allow single permit holders to change employers without restarting the entire application process. It also introduces protections during temporary unemployment. These reforms will create new compliance obligations for employers.
