Mobile Phone Manners
As a courtesy to other attendees, please observe good mobile phone manners. When attending sessions, please turn off your mobile phone and other wireless communications or use the silent notifications options. If you must take a call, please step out of the room rather than disrupting the event. Thank you for your cooperation.

Passport and visa

A valid passport is required for non-EU citizens for entry into GERMANY and the European Union. An identity card is sufficient for citizens of EU Member States. Please consult your local Consulate according to your nationality for specific details.

Advance travel planning and early visa application are important, since entry to Germany with a visa is subject to more intense scrutiny than was previously the case. We highly recommend that foreign participants contact their local embassy to find out what travel documents they will need to visit Germany.

If you do need a visa to attend the workshop, please apply for one as soon as possible.
