Luxembourg

Luxembourg is a trilingual EU founding member with one of the strongest passports in the world, granting visa-free access to 188+ destinations. The economy is dominated by financial services — investment funds, private banking, fintech — and EU institutions, drawing a heavily international workforce; over 220,000 cross-border workers commute daily from Belgium, France, and Germany. Standard naturalisation requires 5 years of legal residence (the final year continuous), B1 spoken Luxembourgish (Sproochentest), and the Vivre ensemble civic course; dual citizenship has been fully permitted since 2009. Citizenship by recovery is available to anyone with a direct ancestor who held Luxembourg citizenship on 1 January 1900 — a notably broad descent route. Personal income tax is progressive to 42% plus solidarity surcharge; high earners face an effective marginal of roughly 45.8%. Healthcare runs through CNS (Caisse Nationale de Santé) — universal cover funded by employer/employee contributions. Luxembourg is an EU and Schengen member. Banking for residents is straightforward at BCEE, BIL, BGL BNP Paribas, and Spuerkeess; non-residents can typically open accounts but face higher minimums. Three official languages: Luxembourgish, French, German.
