Visa regulation and documentation

Invitations for visa purposes can be requested together with the registration of the experiment team through the A-form.

Please check the entry requirements for Germany for nationals of your country before coming to European XFEL.

EU nationals do not require a visa.

In general, all other foreign nationals require visas for stays in Germany.

A visa is not required for visits up to 90 days in an 180‑day period for nationals of those countries for which the European Community has abolished visa requirements.

A list of countries and very detailed information can be found on the webpages of the Federal Foreign Office. Please read carefully and pay attention to the recommended timelines.

Make sure that the correct arrival date / departure date information is given to us in the A-form or in your request in order to avoid unnecessary delays in the processing of your invitation. Normally we add up a maximum of 4 days before and after the scheduled experiment dates in the invitation we provide for travel purposes. Inform us promptly of any specific need related to the duration of your stay.
