After your study visa ends, you can stay in Spain under certain conditions. If you wish to extend your stay, you must apply for a visa extension or switch to a different visa type, such as a work or residency visa, before your current visa expires.
Alternatively, Spain offers a 12-month post-study visa for non-EU students to seek employment or start a business. You must apply within 60 days of your visa expiry and meet financial requirements. Overstaying without proper authorization may result in fines or deportation, so timely action is essential.
