I am a Bhutanese citizen and I would like to go to China to work as I got an invitation form there

Hi, Jambay. You need to prepare a series of materials including your passport and its photocopy, your recent bareheaded color photo, application form, invitation letter from duly authorized entity, a work permit as well as the residence permit or entry permit of the application country and a photocopy of it. After submitting all the required materials, you can wait for the result.
