All non-EU/EEA citizens will need to apply for a student visa if they intend to study in Spain for more than 90 days. This could be a short-term (type C) student visa for courses between 90 and 180 days, or a long-term (type D) visa for any course longer than 180 days.
To study Spanish courses in Argentina or participate in cultural exchange or training programs outside the official education system, for a maximum stay of one year, you can apply for admission through the electronic visa for Non-Statutory Education Students.
Expanish can provide you with the necessary documentation to apply for this type of visa.
