To receive a Letter of Invitation, attendees must :

  • have registered for the ISU 2023 congress!
  • send email to requesting "Official letter of Invitation" for visa purposes and supply following details:
    - copy of your passport
    - your address
    - your date of birth

Individuals requiring an official Letter of Invitation for the IOIS Congress can request one from the IOIS Office. To receive a Letter of Invitation, attendees must first register to the Congress. Registration can be done through your IOIS Account on the IOIS website. When you have registered send a copy of your passport to the IOIS office with the request for an official invitation letter for VISA purposes.

The Letter of Invitation does not financially obligate the Congress organizers in any way. All expenses incurred concerning Congress are the sole responsibility of the attendee.

It is the sole responsibility of the attendee to take care of his/her visa requirements. Attendees who require an entry visa must allow sufficient time for the application procedure (preferably 3 months). Attendees should contact their nearest embassy or consulate to determine the appropriate timing of their visa applications.

If your visa is not granted in time for you to attend the conference and you have paid the registration fee in full, the registration fee minus a handling fee of EUR 50.00 will be refunded not later than 14 days after the congress. You will receive this refund if the visa was applied for in time, and proof of this, together with an official notice from the embassy confirming that a visa could not be granted, is forwarded to IOIS Office.

The organizers will not directly contact embassies and consulates on behalf of visa applicants.
