When crossing a border to enter or leave the Schengen Area¹, as well as when travelling from one country to another within the Schengen Area (including crossing the local borders between the canton of Geneva and the départements of Ain and Haute-Savoie), it is essential to carry a valid identity document (e.g. passport²) that is recognised by the country you are entering. Unless they are specifically exempt, all nationals of countries other than the Member States of the European Economic Area³ and Switzerland must also carry a valid residence permit (residence or settlement permit issued by a Schengen state or passport containing a Schengen visa). In the absence of these documents, entry into the country concerned may be refused.

As is the case for everyone travelling within the Schengen Area, members of the CERN personnel may be subject to an identity check and must be able to present a recognised identity document.

The carte de légitimation issued by the Swiss Federal Department of Foreign Affairs and the titre de séjour spécial issued by the French Ministry for Europe and Foreign Affairs are residence permits, not identity documents. They allow travel within the Schengen area for up to a maximum period of three months (90 days). Official specimens of the documents are available at https://www.sem.admin.ch/dam/data/sem/rechtsgrundlagen/weisungen/visa/vhb/sh-anh20p2-f.pdf and https://www.consilium.europa.eu/ prado/fr/prado-documents/FRA/H/D/docs-per-type.html.

When leaving the Schengen Area, nationals of countries other than the Member States of the European Economic Area and Switzerland who hold those documents must check that they are valid for the duration of their stay outside the Schengen Area. If the documents have expired or you are unable to present them, you may be refused entry on your return.

In case of difficulties at the borders, immigration authorities of the Schengen area may contact:

• for Switzerland, the International Security Police at Geneva Airport, tel. +41 22 427 58 30 (until midnight) or tel. n° +41 22 427 92 20 (24 hours a day);
• for France, the Protocol of the Ministry for Europe and Foreign affairs, tel. +33 (0)1 53 69 30 20 (diplomatic privileges and immunities) / +33 (0)1 53 69 37 69 (consular privileges and immunities), on working days and hours.

If the the French special card or Swiss legitimation card is lost, stolen or forgotten during a stay abroad, the persons concerned are invited to contact directly either the French or the Swiss representation competent for the place of stay in order to obtain a return visa.
