Visa Information and Invitation Requests

Apply now for your Visa! 

If you need a travel visa, begin the visa application process now! You need to allow a minimum of 6 weeks processing time for the entire visa application process (from application for the invitation letter to receiving the visa).Advance travel planning and early visa application are important, since visa applications are subject to a greater degree of scrutiny than in the past. See links below for more information about Visa and passport requirements for travel to Spain.

A valid passport is required for all U.S. citizens and foreign nationals entering Spain. No visa is needed for American visitors staying less than 90 days. All travelers will need a valid passport valid for at least 90 days following your departure date from Spain. It is strongly recommended to travel with a 6 months validity on your passport. Nationals of all Western European countries can visit Spain; US, Canadian, and Australian passport holders can stay up to 90 days without a visa. For additional details and specific visa requirements, please contact the Spanish Embassy in your country.
