Need to go to China in February next year for business so when do l start to apply for a visa

Slyvia, you can start to apply for it in late December or in January next year. You need to prepare your passport and a copy of it, a filled-out application form attached with your recent bare-headed photo, and an invitation letter from your business partner. You should be prepared that there is possibility that the embassy may ask you for an invitation letter from a duly authorized unit in China.
