Is the Canary Islands visa-free?

The Canary Islands belong to the autonomous region of Spain, but they cannot be exempted from visas in Schengen countries. If you want to travel to Spain, you'd better apply for a Schengen visa. Spain is a member of the European Union, so you can use a Schengen visa to go to that country without applying for another visa. The Spanish visa is valid for 9 days, and there is no limit on the number of entries. The stay time shall not exceed 3 days and may be extended to 6 days. Holders of Schengen, British, American, French or Japanese visas will also be regarded as valid visas. The Schengen visa must be submitted directly from the issuing country to the Spanish embassy or consulate in China (Schengen visa only recognizes two consulates in China), and there will be no such thing as "free travel". Visa requirements in Spain are high, and visa officers mainly depend on your economic situation, immigration tendency and so on.
