Dear Sir/Madam,

I am a fasahion Designer andI do most of my production from China but I never visited there persoally. I would like to make a business visit to China. My partners in China Have sent me an invitation letter.They are in the JIANGSU province of China. Is the letter okay to apply for the visa or my partners must apply through the Chinese Foriegn affairs in China first. If so, then which how should they go about it. Thank you. An urgent reply would very much oblige.
