Non-EU students who already have a residence permit for studies or a visa obtained from another EU country and who join the UPV as incoming exchange students (e.g. Erasmus) should not apply for a visa for their stay in Spain. In this case, the student must register at the Foreign Citizen’s Office (Oficina de Extranjería) through the UPV Immigration Support Services, BEFORE their arrival in Spain.

If the Residence Permit of the EU country is not for study purposes, the student should inquire at the corresponding Spanish Embassy to confirm whether s/he should apply for a student visa or not.
