根据您的国籍
以及会议举办地的要求，您可能需要办理签证才能参加。

请联系您居住地附近的该国大使馆/领事馆，核实有关签证的完整要求。

Process to obtain an official invitation letter:

• Register to the congress at least six weeks in advance (the delay for obtaining a visa varies according to the country).
• Once your registration has been paid an invoice is automatically available (and sent by email) - take note of its number.
• 填写以下表格。
• Please note that all visa invitation requests are reviewed by our team, and registration is verified before any invitation is issued (providing the right information will fasten the process).

As the congress date approaches, processing will take up to 3 working days.

We strongly recommend submitting your request well in advance and taking an appointment at the embassy only once you have all required documents.
