Eurocrypt 2025

Visa Information

It is imperative that authors and attendees allow sufficient time to obtain visas.

You can check here whether you need a visa to visit Spain. In particular, citizens from EU/EEA do not need a visa to enter Spain. Visas are obtained in the consulates or embassies of Spain in the country of origin. Requirements and processing times may depend on the origin of the visitor. We recommend investigating the concrete conditions for your case well in advance. In particular, invitation letter requests should be sent early enough.

Invitation Letters

Conference attendees who require a visa will typically need an invitation letter from the General Chair with the subject “Visa Invitation Letter Request”. To expedite the process, please provide as many of the following pieces of information as possible in your request:

• your full name as it will appear on the letter, date of birth, nationality, passport number, and institute
• the title of your paper at Eurocrypt 2025, if applicable
• an up-to-date Curriculum Vitae (CV) that includes, if applicable, a list of publications
• a brief statement explaining your interests in the conference
• a list of any recent IACR conferences you have attended and/or a reference in the crypto community who has attended past IACR conferences

We hope that you will be able to attend Eurocrypt 2025 and help us make the conference a great success.
