You can apply for a non-lucrative resident visa if you have enough money to sustain yourself and your dependents. You are not permitted to work in Spain with this visa.
You must earn a minimum of €25,560 per year, plus €6,390 for every additional family member. Investments, annuities, sabbaticals, and other kinds of income are all possible sources of income.
The visa will be valid for three months and fifteen days, with multiple entries and a stay in Spain of up to 90 days. You must apply for a residence permit and a foreign national identity card within one month of your arrival in Spain.
