We generally need the following details from the congress participant: first name, last name, date of birth, passport number, issued date, expiry date, nationality.
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 to provide any financial support. Invitation letters will be sent by email or upon request by postal mail. In case an express delivery is needed, the delegate shall order a courier at her/his own expense.
