Request for a visa for business trip

Amr, if you plan to frequently visit China for business purposes, I advise you to apply for the one-year multiple-entry M type. The required documents include passport, a copy of the passport's photo page, a filled-out application form attached with your recent color bare-headed photo, and an invitation letter from your business partner in China. If you have previously got PRC entry permits, you should also submit the copied of the previous entry permits.
