Invitation Letters

Requests for invitation letters need to be received by April 15th.

Conference attendees who require a visa will typically need an invitation letter from the General Chair. To expedite the process, please send an e-mail with subject ‘Invitation Letter Request for ‹your name›’ to

In your request provide as many of the following pieces of information as possible:

• your full name as it will appear on the letter,
• your date of birth (if required for the visa application),
• your passport number (if required for the visa application),
• your title (e.g., Professor, Scientist, Engineer),
• your institute as it will appear on the letter (e.g., European Center for Cryptology),
• your mailing address as it will appear on the letter,
• the title of your paper at Eurocrypt 2019 (if any).

  We also need a proof to validate the legitimate need for a letter (e.g., IACR membership, previous publications, link to your homepage, references).

Unfortunately, IACR deals with some fraudulent requests for visa letters. In order to ensure we only write letters for legitimate purposes, we ask you to provide a proof. If none of the above possibilities for such a proof applies, a short explanation of your background and why you want to attend Eurocrypt 2019 is required. We will follow up if necessary.

We hope that you will be able to attend and help us make the conference a great success.
