Citizenship requires 5 years of residence; dual citizenship is permitted. ^[https://guichet.public.lu/en/citoyens/immigration.html]

- **Duration**: 3 years initial, renewable (investment must be maintained)
- **Path to citizenship**: 5 years legal residence; Luxembourgish language exam (A2 spoken, B1 comprehension)
- **Official source**: ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/investisseur/investisseur-pays-tiers.html]
- **Community verdict**: Works well (clear, well-documented process); high investment threshold limits accessibility

### Passive Income Residency
- **Private reasons residence** — discretionary permit for financially independent third-country nationals
- **Conditions**: proof of sufficient, stable income from abroad (no published minimum—typically well above minimum wage); comprehensive health insurance; no gainful employment in Luxembourg; adequate housing. Approval is discretionary; no statutory right. ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/raisons-privees.html]
- **Duration**: 1 year initial, renewable annually
- **Path to citizenship**: 5 years legal residence; 20 of the 60 months must be in the year before application
- **Official source**: ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/raisons-privees.html]
- **Community verdict**: Mixed (discretionary nature = unpredictable outcomes); small applicant pool

### Highly Skilled Employment
- **EU Blue Card** — for highly qualified workers
- **Conditions**: higher education degree (3+ years) or 5+ years relevant professional experience; employment contract ≥1 year in Luxembourg; salary ≥1.5× average gross annual salary (~€78,000/year in 2026; reduced for shortage occupations).

- **Duration**: contract length + 3 months, max 4 years
- **Path to citizenship**: 5 years
- **Official source**: ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/hautement-qualifie/salarie-hautement-qualifie.html]
- **Community verdict**: Works well; high salary threshold reflects Luxembourg's high-wage economy

### Startup Entrepreneur
- **Independent worker residence** — for self-employed non-EU nationals
- **Conditions**: business plan demonstrating economic benefit; professional qualifications relevant to activity; proof of sufficient financial resources; no prior professional card needed (unlike Belgium). Application before entry. ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/travailleur-independant.html]

- **Path to citizenship**: 5 years legal residence
- **Official source**: ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/travailleur-independant.html]

- **Conditions**: job offer; employer passed labour market test (ADEM — national employment agency certifies no suitable EU candidate); salary ≥ social minimum wage (€2,638/mo unskilled, €3,165/mo skilled in 2026). ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/salarie.html]
- **Duration**: tied to contract
- **Path to citizenship**: 5 years
- **Official source**: ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/salarie.html]
- **Community verdict**: Works well (high wages); labour market test is strict

### Student Residency
- **Student residence** — for non-EU students enrolled in Luxembourg institutions
- **Conditions**: acceptance at recognised institution; proof of sufficient means (~€1,000/mo); health insurance. ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/etudiant.html]

### Family Reunification

- **Conditions**: sponsor must hold valid permit ≥1 year; stable income ≥ social minimum wage; adequate housing. ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/regroupement-familial.html]

### Retired Residency
- **Private reasons residence** — discretionary for retirees with sufficient foreign pension/income
- **Conditions**: same as passive income above; non-working; sufficient means; health insurance. ^[https://guichet.public.lu/en/citoyens/immigration/plus-3-mois/ressortissant-tiers/raisons-privees.html]

- **Community verdict**: Mixed (discretionary); limited use

## Citizenship
- **Standard**: 5 years of legal residence (must include 12 continuous months immediately before application)
- **Language**: Luxembourgish — A2 spoken, B1 comprehension (Sproochentest). Also requires attendance of a civic education course (Vivre ensemble au Grand-Duché de Luxembourg, 24 hours).
- **Dual citizenship**: permitted since 2009
- **Cost**: naturalisation fee ~€100
- **EU passport**: yes
- **No automatic jus soli** ^[https://guichet.public.lu/en/citoyens/citoyennete-luxembourgeoise/naturalisation.html]

## Tax
- **Progressive income tax**: 8%–42% (top rate above €220,788). Class 1 (single) first €12,438 tax-free.
- **Impatriate tax regime**: expat employees can exclude 50% of gross salary from Luxembourg tax (max €400,000/year exempt, 5-year limit). Special conditions for R&D specialists. ^[https://guichet.public.lu/en/citoyens/fiscalite/impots-personnes-physiques/regime-impatries.html]
- **Corporate tax**: 17% (plus 6.75% municipal business tax on profits, effective ~24.94% in Luxembourg City). Minimum corporate tax €75–€4,815 depending on balance sheet.
- **No wealth tax** for individuals.
- **VAT**: 17% standard (lowest in EU); 8% intermediate; 3% super-reduced.

## IT / Digital Nomad
No dedicated [[digital-nomad-visa|digital nomad visa]] visa. IT professionals use:
- EU Blue Card (financial sector, EU institutions, Amazon/Google EU HQs)
- Independent worker residence for freelancers
- Luxembourg is a global fintech hub with strong demand for IT/financial professionals and very high salaries.

## Yacht / Maritime
Luxembourg is landlocked. No maritime register. Yacht registration is handled via the Luxembourg Maritime Registry (pavillon maritime luxembourgeois) for commercial vessels only, used primarily for river transport (Moselle).

## Notes for RU citizens
EU sanctions apply. The investor residence route is accessible in principle but requires source-of-funds verification and banking access, both currently difficult for Russian nationals. The Luxembourgish language requirement for citizenship is unique — A2 spoken + B1 comprehension of a small national language. No large Russian-speaking community. Third-country consulates handle applications.

## Country Card

### General description
Luxembourg is a tiny, exceptionally wealthy EU founding member with the world's highest GDP per capita (PPP) and a global financial centre. Its economy is dominated by banking, investment funds, and EU institutions. Luxembourg offers a uniquely structured investor residence permit (from €500,000), an EU Blue Card (salary ~€78,000 threshold), and one of the most generous impatriate tax regimes in the EU (50% salary exemption). Citizenship is available after 5 years with a Luxembourgish language exam (A2 spoken, B1 comprehension) — dual citizenship is permitted.

### Well-known strong points
- World's highest GDP per capita PPP (~$143,000) and highest median salary (~$5,640/mo)
- Generous impatriate tax regime: 50% salary exemption (max €400,000/yr)
- Fast citizenship: 5 years with dual citizenship permitted
- Dedicated investor residence permit (from €500,000 with clear criteria)
- Very high Rule of Law (WJP 0.81) and political freedom (FH 97/100)
- Multilingual environment (French/English/German widely spoken) and excellent quality of life

### Well-known problems
- Very high cost of living: Numbeo index 64.8; rent ~€1,600 for 1-bedroom
- Luxembourgish language requirement for citizenship (unique — small national language)
- No digital nomad visa; no dedicated passive-income or retirement route
- Small, expensive housing market with limited supply
- Landlocked; limited cultural/entertainment scene compared to larger neighbours
- High salary thresholds for work permits (Blue Card ~€78,000) reflect high-wage economy

## Status
- **Last monitored**: 2026-10-12
- **Recent changes**: Impatriate tax regime maintained. No major immigration reform in 2026.
- **Watch items**: EU Blue Card salary threshold adjustments. Track investor residence approval statistics.
