Which Lawyer Helps Startups Hire Foreign Workers in Belgium?
Hiring international talent is one of the fastest ways for a Belgian startup to scale, but it comes with real legal complexity. From single permits and EU Blue Cards to regional salary thresholds and labour-market tests, getting it wrong can mean fines, delays, or a rejected application. An employment lawyer in Brussels who understands both labour law and professional immigration is the missing piece most founders overlook. This guide explains the permit landscape, common pitfalls, and exactly how a specialised firm like Tine Avocat supports startups through every step of the process.
Why Startups Need a Lawyer to Hire Foreign Workers
Belgium's immigration system is employer-driven. That means the company, not the employee, bears primary responsibility for submitting the work authorisation application. According to Belgium.be, non-EU/EEA nationals who wish to work as employees must hold a valid work permit before starting.
For startups with lean teams and no in-house HR legal counsel, this creates a knowledge gap. A labour-market test may be required, contracts must meet specific salary thresholds, and each of Belgium's three regions applies slightly different rules. An employment law practice focused on growing companies bridges that gap by handling applications, drafting compliant contracts, and advising on ongoing obligations.
Work Permit Types Available in Belgium
Belgium offers several pathways depending on nationality, skill level, and duration of stay. The table below summarises the most relevant options for startups.
| Permit Type | Who It Covers | Validity | Key Requirement |
|---|---|---|---|
| Single Permit (A Card) | Non-EU employees, stays > 90 days | Up to 3 years, renewable | Labour-market test + employment contract |
| EU Blue Card (H Card) | Highly skilled non-EU workers | Up to 4 years | Min. salary ~EUR 55,000 + recognised diploma |
| Work Permit B | Short-term or cross-border assignments | Up to 12 months | Employer-specific, proof of labour need |
| Professional Card | Non-EU self-employed / corporate mandates | Varies by region | Demonstrate economic interest |
Choosing the wrong category wastes months. A lawyer experienced in recent employment law developments ensures you apply under the right framework from day one.
The Single Permit: Belgium's Default Route
A Single Permit is a combined work and residence authorisation for non-EU nationals employed in Belgium for more than 90 days. Since its introduction in January 2019, it has replaced the old two-step process of separate work and residence permits, reducing paperwork for employers. The application is jointly processed by the federal Immigration Office and the competent regional authority.
Employer Obligations
The employer must submit the application and provide a Dimona declaration for employees subject to Belgian social security. You also need a compliant employment contract that meets or exceeds regional salary minimums. Startups should factor in processing times of 8 to 16 weeks on average.
Unlimited Duration Option
Since early 2023, Belgium offers a Single Permit of unlimited duration for workers who have been legally employed for a considerable period. This allows holders to change employers freely, making it attractive for retention in competitive tech markets.
EU Blue Card: When Does It Make Sense?
The EU Blue Card is a residence and work permit specifically designed for highly skilled non-EU workers who meet education and salary criteria. In practice, the regional single permit is applied for far more often than the Blue Card because the salary threshold is higher and seconded employees are excluded. According to Baker McKenzie, the practical relevance of the Blue Card remains somewhat limited due to its narrow scope and administrative burden.
That said, the Blue Card offers real advantages for startups planning EU-wide expansion: longer validity (up to 4 years) and easier intra-EU mobility for the holder. Recent Brussels-Capital Region rules have also relaxed conditions for IT professionals. Discuss both routes with your lawyer to pick the best fit.
Regional Differences That Catch Startups Off Guard
Belgium's work authorisation system is regionalised. Flanders, Wallonia, and the Brussels-Capital Region each set their own salary thresholds, processing procedures, and exemption categories. For 2025, the minimum gross salary for a highly qualified employee varied significantly:
| Region | Annual Highly Skilled Threshold (2025) |
|---|---|
| Flemish Region | EUR 48,912 |
| Brussels-Capital Region | EUR 44,441 (~EUR 3,703/month) |
| Walloon Region | EUR 53,220 |
Startups headquartered in Brussels but with remote employees in Flanders need to know which region's rules apply. Your employment law consultation should address this from the outset to avoid filing with the wrong authority.

Frequently Asked Questions
Do EU citizens need a work permit to work at a Belgian startup?
No. Citizens of EU/EEA countries and Switzerland benefit from free movement rights and do not require a work permit. They only need to register with local municipal authorities after three months of residence.
What is a Single Permit in Belgium?
A Single Permit is a combined work and residence authorisation for non-EU nationals staying in Belgium for more than 90 days. It replaced the earlier dual-application system in January 2019 and is processed jointly by federal and regional authorities.
How long does a Belgian work permit application take?
On average, processing takes between 8 and 16 weeks depending on the region, the completeness of the file, and the type of permit requested. Working with an experienced lawyer can reduce delays caused by incomplete documentation.
What is the labour-market test?
A labour-market test is a requirement in which the employer must demonstrate that no suitable Belgian or EU candidate is available for the position. Highly qualified employees earning above regional salary thresholds are often exempt from this test.
Can a startup use the EU Blue Card instead of a Single Permit?
Yes, but the Blue Card has stricter requirements: a minimum salary of approximately EUR 55,000 and a recognised higher-education diploma. It is most useful when the employee needs intra-EU mobility. For most startup hires, the Single Permit is more practical.
What happens if a work permit expires before renewal?
The employee must stop working immediately, and the employer must submit a renewal request. To avoid disruption, employers should file renewals well in advance of the expiry date.
Does Tine Avocat handle immigration cases for startups?
Yes. Tine Avocat advises companies on all aspects of employment law including expatriation contracts and professional immigration. The firm is based in Brussels and has over 13 years of experience supporting employers through permit applications and labour court proceedings.
Which Belgian region processes my permit application?
The competent region is generally determined by where the employee will work, not where the company is registered. Each region has its own online portal and conditions, so verifying the correct jurisdiction before filing is essential.
