Participants can request an official invitation letter via the online registration system used for registering for the conference. The official invitation letter will only be issued to participants who have registered for the conference and who have paid their registration fee in full.
Please note that the letter aims to assist participants who need to obtain a visa, or permission to attend the Conference, and is not an official invitation letter covering fees or any other expenses for you as participant.
While we wish to assist our participants by providing the visa invitation letter, EWMA does not contact the Embassy or Consulate on behalf of participants and is not in a position to influence Embassy / Consulate procedures or decisions.

The earliest you can apply is 3 months before you travel. Check the guide processing times to find out how long getting a visa might take in the country you’re applying from. If a participant’s application for visa is refused, the conference secretariat will refund the paid registration fees only when a copy of the refusal letter is received before 14 April 2020.
