Obtaining an investment residency in Spain involves the following steps:

Choose the right visa category: There are several visa categories for investment residency in Spain, including the Golden Visa, Non-Lucrative Visa, and Entrepreneur Visa. Choose the one that best fits your circumstances and investment plans.

Determine your eligibility: To be eligible for an investment residency in Spain, you must have sufficient financial means and a clean criminal record. Additionally, you must have a valid passport and not have been barred from entering Spain.

Gather required documents: Depending on the visa category you choose, you will need to provide various documents, such as a passport, birth certificate, police clearance certificate, proof of financial means, and proof of health insurance.

Make an investment: The most common investment for obtaining residency in Spain is the purchase of real estate. You must make an investment of at least €500,000 in Spanish property to be eligible for the Golden Visa.

Apply for the visa: Once you have gathered all required documents and made your investment, you can submit your visa application to the Spanish Consulate in your home country. You may also need to attend an interview with consular officials.

Wait for a decision: The processing time for a residency visa can vary, but typically takes several months. Once a decision has been made, you will be notified of the outcome.

Move to Spain: If your visa application is approved, you can move to Spain and start the process of obtaining a residency card, which will allow you to live in the country for up to two years. After two years, you can apply for permanent residency.

It's important to keep in mind that the process of obtaining investment residency in Spain can be complex and may require the assistance of an immigration lawyer or professional.
