Visa
American citizens wanting to study, reside, or work in Spain must obtain the appropriate visa from the Spanish Embassy or Consulate in their state/country of last residence.  After the visa has been issued, foreigners have three months to apply for the corresponding permit with the Spanish authorities in Spain.  Obtaining a residence or work permit is a complicated process; since regulations change continually, we suggest that you write directly to the:

Spanish National Police
Calle Moratin, 43
28014 Madrid
