If you hold a passport from a non-European country, the USA or Japan, you will probably need a visa.

The Invitation Letter from the ESRF indicating your scheduled beam time may not be sufficient to obtain a French visa. Contact the French Embassy or French Consulate for information on documents to provide (the ESRF cannot give any information on visa matters).

You must apply for a visa

Please apply for a visa at least 1 month before your expected departure for Grenoble.
