One might wait for a couple of months to get a Schengen Visa, therefore it is recommended that you register as soon as the registration opens and apply for your visa. Invitation letters will be sent upon request only.
The congress organisation will be pleased to send a formal letter of invitation to delegates requesting an invitation letter for visa purposes. It is understood that such an invitation is intended to help potential delegates to raise funds or to obtain a visa. This does not imply a commitment from the congress organisers to provide any financial support. The organisers may ask for reference letters from people asking for formal letters of invitation at their discretion. Please register for the conference before requesting an invitation letter. For the invitation letter and/or more information, please contact participants [at] discongress [dot] com (DIS Congress Service).
Letters will be sent electronically unless a paper copy is requested. Please note that we have been assured by the Danish Embassy in Beijing that an electronic copy is sufficient if it is obvious that is was sent from an official source (like DIS Congress Service).
