If you plan to attend EUCASS 2013 and you require a visa for travel, you must apply for a visa with the missions of the Federal Republic of Germany, i.e. its embassies and consulates-general with ample time for processing. Please note that EUCASS 2013 will not directly contact German Federal Foreign Office, consulates, or embassies on behalf of individuals applying for visas. For details on the visa regulations and whether you are requiring a visa or not, please consult German Federal Foreign Office.
EUCASS 2013 provides an official letter of invitation through an external service provider upon the request of a prospective attendee who requires a visa to travel to Germany. This letter as well as a copy of event materials (e.g. call for papers) should be presented along with the visa application.
In order to receive a "Letter of Invitation" you have to properly register for the conference. During registration process you will be asked whether you require an invitation and - in case - for your passport number. The invitation will be sent out as soon as the registration fee has been credited.
