What are the documents needed for visa application of a Chinese friend who invited me to go there?

Hi, you can apply for a tourist L type for that, and you are supposed to prepare a filled-out application form, 2 passport-style photos, your passport and its photocopy, round trip air tickets and hotel reservation as well as your travel plan or an invitation letter from your student, bank statement, tax certificate, identity card, as well as other documents the consular officers consider necessary.
