Which Lawyer Helps Startups Hire Foreign Workers in Belgium?
Hiring international talent is one of the biggest growth levers for startups in Belgium, but it comes with a maze of immigration rules, regional permit variations, and strict employment law requirements. A single missed deadline or incomplete file can delay your new hire by months. The right employment lawyer does not just fill out forms. They guide you through the Single Permit procedure, draft compliant contracts, and ensure your company meets every obligation from Dimona declarations to social security registration. This guide explains exactly what to look for and how the process works.
What Is the Single Permit (Permis Unique)?
The Single Permit is a residence permit granted in connection to employment that allows non-European citizens to reside and work in Belgium for more than 90 days. It combines work authorization and residence rights into one document and one procedure, eliminating the need for separate applications.
The employer initiates the application through the Working in Belgium online platform. Two authorities must approve it: the competent regional employment authority and the federal Immigration Office (Office des Etrangers). The entire procedure takes a maximum of 120 days from the moment the file is complete.
Types of Work Permits for Foreign Employees
Belgium offers several pathways depending on the worker's profile:
- Single Permit for Highly Qualified Workers - the most common route for startup hires, requiring a higher education diploma and a salary above regional thresholds.
- EU Blue Card - targets highly educated professionals with a higher salary requirement (approximately EUR 66,000+ annually in Brussels) and offers enhanced intra-EU mobility.
- Shortage Occupation Permit - for roles on official bottleneck profession lists, with less strict conditions and a permit valid for up to one year.
- Intra-Corporate Transfer (ICT) Permit - for managers, specialists, and trainees transferred within multinational groups.
- Professional Card - for non-EU entrepreneurs or self-employed founders, separate from employee work permits.
A startup employment lawyer in Brussels can assess which category best fits your candidate and maximize approval chances.
Regional Salary Thresholds at a Glance
Belgium's federal structure means each region sets its own minimum salary for highly qualified workers. These amounts are indexed annually. The table below shows indicative 2025/2026 figures:
| Region | Highly Qualified (Annual Gross) | EU Blue Card (Annual Gross) | Under-30 Reduction |
|---|---|---|---|
| Brussels-Capital | ~EUR 51,551 | ~EUR 66,092 | Not applicable |
| Flanders | ~EUR 48,912 | ~EUR 66,092 | 80% of threshold |
| Wallonia | ~EUR 53,220 | ~EUR 66,092 | 80% of threshold |
Offering a salary below the applicable threshold will result in automatic refusal. Your lawyer should verify the indexed amounts at the time of application, as they change every year. For broader guidance on structuring competitive pay, see our article on how to boost your employees' salaries.
Why Startups Need a Specialized Employment Lawyer
Startups face unique challenges that make generic legal advice insufficient. First, most founders have never navigated Belgian immigration procedures before. Second, startups often hire across borders rapidly, meaning multiple applications may run simultaneously in different regions.
Compliance Beyond Immigration
Hiring a foreign worker triggers obligations well beyond the permit itself. The employer must submit a Dimona declaration, register with the ONSS (National Social Security Office), draft a Belgian-law employment contract, and comply with the applicable joint committee's minimum pay scales. An employment lawyer who understands both immigration and Belgian labour law can bundle these steps efficiently.
Avoiding Costly Mistakes
If authorities discover that a worker is present in Belgium without a valid residence permit when the Single Permit application is submitted, the application is automatically refused. Similarly, an incomplete file restarts the 120-day clock. For a startup competing for talent, these delays can mean losing a candidate to a competitor.
What an Immigration-Savvy Employment Lawyer Does
An employment lawyer specializing in professional immigration is a legal professional who advises employers on every step of hiring non-EU workers, from permit strategy to employment contract drafting and social security registration.
Here is what this looks like in practice:
- Permit strategy: Assessing which permit category fits the candidate's profile and the startup's structure.
- Document preparation: Compiling diplomas, translations, employment contracts, proof of salary, and vacancy justification.
- Application filing: Submitting the dossier via the Brussels Economy and Employment portal or the relevant regional authority.
- Contract drafting: Ensuring the employment contract meets Belgian mandatory provisions, including probation rules, notice periods, and non-competition clauses.
- Post-arrival compliance: Guiding the employee through municipal registration (Annex 49) and coordinating family reunification if needed.
How to Choose the Right Lawyer in Brussels
Not every employment lawyer handles immigration files. When evaluating firms, consider these criteria:
Sector Experience
Look for a lawyer who regularly advises startups and scale-ups. These businesses have different needs than multinationals: leaner HR teams, faster hiring cycles, and equity-based compensation structures that require specific contractual attention.
Full Employment Law Coverage
Immigration is only one piece of the puzzle. Your lawyer should also cover employment contracts, work regulations, dismissal procedures, and social security disputes. At Tine Avocat, for instance, Maitre Tine has over 13 years of experience advising companies on managing employment relations, RGPD compliance, and social protection, offering strategic solutions in both prevention and litigation.
Responsiveness and Language
Brussels is multilingual. Your lawyer should be comfortable working in French, Dutch, and English to handle regional authorities in any part of Belgium and to communicate effectively with international hires. Check whether the firm offers a consultation to discuss your situation before committing.

Frequently Asked Questions
What is the Single Permit in Belgium?
The Single Permit (permis unique) is a combined work and residence authorization for non-EU nationals employed in Belgium for more than 90 days. It merges what used to be separate work permit and residence permit applications into one streamlined procedure.
How long does a Single Permit application take?
The maximum legal processing time is 120 days from the moment the regional authority has a complete file. In practice, many applications are resolved within 3 to 4 months. Delays often result from missing documents or additional labour market checks.
Who files the Single Permit application: the employer or the employee?
The employer (or their authorized representative) must file the application. The employee cannot submit it themselves, except when applying for an unlimited-duration Single Permit after several years of employment in Belgium.
What salary must a startup offer to qualify for a highly qualified worker permit?
The minimum gross annual salary depends on the region: approximately EUR 48,912 in Flanders, EUR 51,551 in Brussels, and EUR 53,220 in Wallonia (2025 indexed figures). Workers under 30 may benefit from a reduced threshold (80%) in Flanders and Wallonia.
Can a foreign worker start working before receiving the Single Permit?
No. The employee can only begin working after receiving all required documents, including the Single Permit card issued by the municipality. Starting work prematurely exposes both employer and employee to sanctions.
Does an employment lawyer also draft the employment contract?
Yes. A specialized employment lawyer drafts the Belgian-law employment contract, ensuring it includes all mandatory clauses such as job description, salary, working hours, notice periods, and any restrictive covenants. This is critical because the contract is a key document in the permit application.
What happens if the Single Permit is refused?
The employer can lodge an appeal or submit a new application with corrected documentation. An employment lawyer can advise on the grounds for refusal and the best course of action, whether that is an administrative appeal or a fresh filing.
Why should a startup choose a Brussels-based employment lawyer?
Brussels is both the capital region and the seat of most federal authorities, including the Immigration Office. A lawyer based in Brussels has direct familiarity with Brussels Economy and Employment procedures and can also handle files in Flanders and Wallonia when needed.
