The Embassy serves both Switzerland and Liechtenstein for diplomatic matters. Swiss travelers to French overseas territories (Martinique, Guadeloupe, Réunion, French Guiana, Mayotte, French Polynesia, New Caledonia, Saint-Martin, Saint-Barthélemy) should verify specific entry requirements as Schengen rules do not uniformly apply. France and Switzerland cooperate extensively on cross-border matters including transportation (TGV Lyria high-speed rail), environmental protection (Lake Geneva, Alpine cooperation), and security coordination. The bilateral relationship benefits from geographic proximity, linguistic ties in Romandie, and shared membership in European frameworks.
