Visa and Letter of Attestation

Participants are strongly advised to make sure they fulfill all legal requirements to enter Spain.
Besides a valid passport, an entry visa may also be required. Please visit the official website of the Spanish Ministry of Foreign Affairs to find out whether, depending on your citizenship, country of long-term residence, and the duration and reasons for your stay, you need a visa to enter Spain.

It is highly recommended to start the process a minimum of 2 ½ months prior to your arrival in Spain. Please contact your nearest Spanish consulate or embassy in your country of residence for further information.

It must be understood that such letters do not imply any financial support or hosting arrangement from LHCP2013, nor a guarantee of a visa being issued.

The attestation letter to assist in visa formalities will only be sent on request and only to participants who have paid their registration fees in full. Should you wish to receive a letter, please note that your request must be registered as early as possible by filling in the appropriate fields in the on-line registration form or by sending an email to
