If the student is selected for a period of mobility, they should immediately go to the GRI to fill in the necessary forms and hand in the following documentation: two copies of the learning agreement duly signed by the Erasmus Coordinator at their school, the application form from the host HEI, two passport-sized photographs, a photocopy of their identity card and NIF or Citizen Card.
You should also find out more about the host HEI by consulting their website and, in particular, find out about their deadlines.
