Working in Brussels: EU institutions, key sectors and life as a French-speaking expat

◆What makes Brussels different

For a French citizen, it's one of the simplest moves: no visa, a language you share, and a dense market. That doesn't mean you land there without a method. The city is French-speaking, ninety minutes from Paris by train, and it concentrates a density of opportunities you rarely find elsewhere. As the capital of the European Union, it draws institutions, NGOs, lobbies and regional or national representations, on top of a solid base of finance, consulting and tech.

You'll find a sizeable international community here and a real French one, which changes a lot when you arrive. I'll be honest on one point: the language pressure is lower than elsewhere, because you can work and live in French day to day. Dutch is a genuine asset — Belgium is trilingual, with German too — but it isn't a prerequisite for most international roles in Brussels. So my advice is not to let it become a mental block before you've even applied.

◆Your right to work, concretely

Because Belgium is an EU country, as a French national you enjoy free movement. No visa to apply for, no work permit to obtain: you can arrive, look for a job and sign a contract just like a local. That is, to my mind, what makes a move to Belgium so accessible.

The only formality is administrative registration. If you settle for more than three months, you must register with your local municipality (commune) to get a certificate and then an EU citizen residence card. The steps are simple in principle, but I've seen timelines and required documents vary noticeably from one commune to another. So check the exact procedure on the official belgium.be portal and directly with your commune, rather than relying on a friend's account from three years ago.

◆Salaries, taxes and cost of living

Gross salaries in Brussels are solid, often comparable to or higher than Paris for international roles, and the EU-institutions market pulls some levels upward. You do need to be clear-eyed, though: Belgium is known for relatively high taxes on labour, with social contributions and income tax that weigh on take-home pay. For the same gross salary, what's left in your pocket can be tighter than you'd imagine, and I'd rather say so before you discover it on your first payslip.

In return, social protection is strong, and some roles — notably in the institutions and international organisations — benefit from special tax regimes or statuses. On cost of living, Brussels remains reasonable compared with Paris or London, especially on housing. To size your budget, lean on recognised indices such as Numbeo or the Mercer rankings rather than rough numbers, and keep in mind that taxes and price levels change: what's true today may not hold next year.

◆How French people get there

There's rarely a single right way to land in Brussels, which is reassuring. The routes I see most often look like this:

• Direct application: free movement lets you apply like a local in finance, consulting, tech or with private employers in the EU-affairs sector.
• EU competitions and careers: the institutions recruit their officials through EPSO (European Personnel Selection Office) competitions, a demanding but structured route.
• Institutional traineeships: the Schuman traineeships at the European Parliament or the Blue Book at the European Commission are classic ways to get a foot in the ecosystem.
• V.I.E. (International Corporate Volunteering): via Business France, a first sponsored experience at a French company based in Belgium.
• Public affairs and NGOs: lobbying, advocacy, regional representations and associations hire many bilingual French-speaking profiles.

◆The local hiring codes

In Brussels, the Europass format is widespread, especially in the institutions and EU-affairs world: a structured, clear CV that highlights your languages and international experience. In the classic private sector — finance, consulting, tech — a more standard one-to-two-page CV is fine. I'd advise you to polish the cover letter, still genuinely valued in Belgium, where it's fading elsewhere.

Languages are a real differentiator, and part of your application is decided there. French covers many roles, English is almost essential in international settings, and Dutch opens extra doors, particularly with Flemish employers and Brussels public functions. State your real level for each language: it's looked at closely, and an exaggeration shows quickly in an interview.

◆Network and the French community

The French and French-speaking community in Brussels is enormous, which makes arriving much easier. Between Franco-Belgian chambers of commerce, expat clubs, French-language schools and dedicated media such as lepetitjournal.com, you have plenty of ways to build a network quickly, without starting from scratch.

In the EU-affairs ecosystem, networking matters a lot, sometimes as much as the application itself. Conferences, think tanks, professional events and sector associations are where opportunities circulate, often before they're posted. Don't overlook regional employment services either, such as Actiris in Brussels, which support job seekers.

◆Settling in once you're there

Once on the ground, the logical order is fairly clear: choose your municipality, each with its own character and local taxation, complete your registration to get your EU citizen residence card, then join a mutuelle (health insurance fund) for healthcare coverage. Opening a Belgian bank account then smooths out salary payments and rent.

Brussels is a human-scale, well-connected city where you settle in fast. Take the time to compare municipalities based on your workplace and housing budget, because the gaps are real. And I'll say it plainly again: Belgian admin can be finicky, so keep all your documents and verify each step on belgium.be and with your commune.
