All American citizens wishing to enter Spain to reside and work need to hold a long-term visa, unless they are also citizens of the European Union (EU), Iceland, Liechtenstein, Norway or Switzerland.
Applications for these visas must be submitted through a duly completed application form filed in person in the town or city where the Diplomatic Mission or Consular Office is located. However, applications may also be filed by a duly accredited representative if you can demonstrate due cause.
When submitting an application for a visa, you must pay an established fee (generally € 60) and the deadline for processing this application is one month after the application has been submitted. The issued visa must be collected personally at the Diplomatic Mission or Consular Post.
