A temporary residency allows you to stay on the islands for between 90 days and five years. Permits for less than five years can be renewed every year at the subject's request.
What happens if I stay in Spain longer than 3 months?
Entry bans – If you're caught travelling in Spain – or any other Schengen country – past the 90-day period, you could be banned from re-entering for up to 3 years. Prison sentences – Staying in Spain for over 90 days in any 180 days without a valid visa can result in jail time.
