Moving to Luxembourg: A First-Steps Guide for Expats

Luxembourg is easy to underestimate. It is small enough to cross in an hour, and it contains one of the largest financial centres in Europe, a substantial EU institutional presence, and a population that is close to half foreign nationals - with a further enormous daily inflow of cross-border workers from Belgium, France and Germany.

That produces a genuinely unusual place: multilingual by necessity rather than policy, very international, very well paid, and with a housing market that has become the defining constraint on living there.

The right to stay

EU, EEA and Swiss citizens may live and work in Luxembourg. You make a declaration of arrival at your commune within days of moving in, and register your residence after three months.

Non-EU nationals generally need to apply for temporary authorisation to stay before travelling, then make the arrival declaration and apply for the residence permit once here. The common categories are salaried worker - usually with the employer demonstrating the vacancy was notified to the employment agency - the EU Blue Card for higher-qualified roles, intra-company transfer, study, family reunification, and investor routes. The current picture is in the Luxembourg visa section, and the general employer-side mechanics are in how employer visa sponsorship works.

Given the size of the finance and EU sectors, a large share of arrivals come through an employer who has done this many times, which makes the process comparatively smooth.

The language question, which is genuinely unusual

Three official languages: Luxembourgish, French and German. Plus English, widely used across finance, EU institutions and the international sector.

In practice: French is the most useful for daily life, shops and services, and much of the service workforce is francophone cross-border. German appears heavily in written administration, media and the early school system. Luxembourgish is the language of national identity, of much informal life among Luxembourgers, and of naturalisation requirements. English will carry you a long way professionally and not very far socially outside the international bubble.

Nobody expects you to arrive with all of these. But the distribution explains a lot about how the country feels: it is entirely possible to live here for years, functioning in English, and remain at some distance from Luxembourgish life. The general argument for doing something about that is learning the local language fast.

The school system is a real consideration for families: the public system is multilingual with Luxembourgish, German and French introduced in sequence, which is excellent for children who grow up in it and demanding for a child arriving mid-way. International and European schools exist, and the choice is a significant one - see international versus local schools.

Healthcare

A compulsory social insurance system funded through contributions from employment, with membership of the national health fund and generally good access and short waits. As in Belgium and France, reimbursement is a large percentage rather than free at the point of use, and supplementary cover is common to close the gap.

Given the country’s size, some specialist and hospital treatment is provided across the border under arrangements that work smoothly. Details in the Luxembourg healthcare section.

Money, tax and the honest arithmetic

Salaries are among the highest in Europe, particularly in finance, law, audit and EU-related work. Income tax is progressive with a class system that reflects marital and family situation, and social contributions are moderate by regional standards. The result is a genuinely high net income by European norms.

And then there is housing. Luxembourg’s property market has risen dramatically over two decades, driven by strong demand and constrained supply in a country with very little space. Buying is out of reach for many people who would be comfortable buyers elsewhere; renting in the city is expensive.

The country’s answer, at scale, is cross-border living. A very large share of the workforce commutes daily from Arlon in Belgium, Thionville and Metz in France, and Trier in Germany, where housing costs a fraction of Luxembourg City’s. If you do that, your tax and social security position becomes a treaty question determined by where you reside and work, and it needs proper advice rather than assumptions - tax residency explained covers the principle and avoiding double taxation the relief mechanisms.

Structure is in the Luxembourg tax section.

Daily life

Public transport within the country is free - buses, trams and trains in standard class - which is a genuine and pleasant oddity, though it does nothing for the cross-border congestion that shapes the morning commute.

The country is compact enough that weekends in Brussels, Paris, Cologne or the Moselle vineyards are ordinary rather than expeditions. Luxembourg City itself is small, handsome and quiet; the Ardennes north and the industrial south are different countries in miniature.

The international community is large and easy to join. The flip side, familiar from Brussels, is that it is possible to spend years entirely within it. Luxembourgers are a minority in their own capital and their social world takes longer to enter - clubs, language and time being the routes, as everywhere.

Staying permanently

Luxembourg’s naturalisation route is notable for two reasons. The residence requirement is comparatively accessible by European standards, and the country permits multiple nationality, so acquiring a Luxembourgish passport does not require giving up your existing one - though your country of origin may take a different view, which is the check people forget.

The binding requirement for most applicants is Luxembourgish. There is a spoken language test and a civics course, and the language element is what determines most people’s timeline, because Luxembourgish is not a language you will pick up incidentally while working in English or French. Courses are widely available and heavily subsidised, and starting early rather than in your qualifying year is the difference between a formality and a scramble.

There is also a route based on ancestry for descendants of Luxembourgish nationals, which is worth checking if your family has any connection at all - a surprising number of people qualify without knowing.

Permanent residence is a separate and simpler step available earlier, and it is worth taking when you qualify even if the citizenship question stays open. The general mechanics are in the path to citizenship and naturalisation.

What catches people out

Assuming the high salary translates into an easy housing search. Not thinking through the cross-border tax and social security position before taking a job. Underestimating how much the multilingual school system asks of a child arriving at nine or ten. And expecting a country this small to have big-city amenities in every direction - much of what you will do at the weekend happens in another country.

For the regional comparison, moving to Belgium is where a great many Luxembourg workers actually live, moving to the Netherlands is the other Benelux option with a different set of trade-offs, and moving to Germany covers the eastern neighbour.

Detail on permits, the housing market and costs is in the Luxembourg country guide and the cost of living section. For current cross-border commuting realities and which side of which border people recommend, the general forum is the place to ask.
