All delegates are responsible for establishing their own entry requirements to Germany. Those requiring a visa should allow adequate time for obtaining this. The congress organisation will be pleased to send a formal letter of invitation to delegates requesting an invitation letter for visa purposes. The invitation letter will be sent as an e-mail attachment and is sent on the understanding that it is intended to help potential delegates to raise funds and/or to obtain a visa. The invitation letter carries no commitment from the congress organization to provide any financial support. Please contact the congress organization for processing an invitation letter (

Please note: If you are registered for the congress and your visa application is rejected the congress organization will only refund the registration fee excluding a handling fee of 30€. It will not be possible to refund any additional services you have booked  (e.g. social events). Under these circumstances, in order to obtain a refund a written application must be submitted to the congress organization and proof of the rejection of a visa application by the German authorities must be provided.  All refund applications must be received by the congress organization no later than one week before the start of the Congress i.e. 17:00 (Central European Time) Tuesday 9th July 2019. All registrations are made on the understanding that delegates accept the above conditions.
