The host university will verify, upon starting the admission process to the doctoral programme, that the studies taken up by the selected candidates make them eligible to enrol in an official doctoral programme in accordance with the regulations in force in Spain or Portugal. Should they be found not eligible after verification, the fellowship will be withdrawn. Under no circumstances may candidates have previously enrolled in the same doctoral studies for which they are applying for the fellowship.
