Regarding the reference letter please note the following:
Only one letter is required in order for your application to be complete.
The reference letter should be written in English, Greek or French (otherwise translation will be necessary).
For a reference letter to be valid when scanned and uploaded by the applicant: It must be written on the official head paper of the university and be signed. When it is sent directly through the professor’s email it is sufficient if the university’s email address has been used.
For applicants who choose the email request option: An automated email will be sent to the proposed referee requesting for the reference letter (please keep in mind that the referee will also have to check his junk E-mail folder). Most importantly, the responsibility to do the follow up lies with you: You will have to liaise with your referee and check regularly the status of your application in order to confirm that the letter has been submitted by the deadline of the 15th of June.
