Spain is one of the 26 EU countries of the Schengen Agreement. These countries issue a visa called the Schengen visa, which allows to travel to or through all the Schengen area within the validity of the visa. If you intend to visit a Schengen country, you must apply for a Schengen visa at the Embassy or Consulate of that country. Visa requirements are different according to each country. Participants are requested to check with the Portugal consulate or diplomatic mission in their home country. It is the responsibility of the participant to obtain a visa. Please note that the average time for obtaining a visa can be from two to six weeks from the date of application. The costs for visas varies depending on the intended length of stay, etc. https://www.schengenvisainfo.com/portugal-visa/
