I m from Tunisia .and want to go to China

Kaether, is the visit related to business purpose? If yes, you need to apply for an M type. If it's just for sightseeing purpose, I would suggest you apply for the L type. It will be easier. If you apply for the L type, you need a valid passport, a photocopy of the passport's photo page, a filled-out application form with your bare-headed photo, round-trip tickets and hotel reservations, and bank statement. If you apply for the M type, you don't need to show tickets and hotel bookings, but you need to get an invitation letter from the company, plus a work certificate and your company's tax return form.

The process needs four working days.
