The type of visa or work permit required to visit, study or work in Spain depends largely upon both the applicant's citizenship and his or her desired length of stay. Once granted, a specific type of visa cannot be changed without first returning to one's home country; thus, it is important to apply for the correct visa from the outset. In general, the application process for all travel documents takes several weeks and the costs vary depending upon the type of visa or permit required. Most applications must be submitted in person or by appointment through an email request to the consulate or embassy of jurisdiction in one's home country.

This is just a sample of what you'll find in the complete Spain guide.
