how i can apply for visa and what documents require to be submit?

Hi Muhammad! Do you want to conduct business activities by visiting the exhibition? If yes, you need to apply for an M type. To begin with, prepare the following materials, including your passport, passport copy, application form, recent passport size photo, an invitation letter from Duly Authorized Unit, an invitation letter from the exhibition hosting party or your trade partner, a guarantee letter from your company, a photocopy of your income tax return form or business licence of your company, and bank records of latest six months. If it's your first visit to China, round trip tickets and hotel reservations are also required. Then you can go to the embassy and submit all the documents.
