Please anyone to provide me with a list of documents I need for a Multiple entry M visa.

OK, you need to submit the following documents: 1. a passport valid for at least six months and having at least two blank pages; 2. a photocopy of the passport's data page as well as the used pages; 3. a duly completed application form attached with your color bare-headed photo taken within six months; 4. an invitation letter from your trade partner in China.
