How does an American visiting Spain apply for a visa to visit China from Spain?

First, you need to collect all documents you may need, including your passport, a photocopy of the passport's used pages, a filled-out application form with a half-length photo of yours stuck on the first page, the original and photocopy of your entry permit for Spain, and round-trip tickets and hotel bookings for the coming trip. Then go to the CVASC office in Madrid to apply for an L type.
