The Visa Councilor
Dear Sir / Madam
I am doing job in a business firm. Already visited China several times with Double Entry, Six months multiple entry and One year Multiple Entry. Soon I need again to go China to visit the factories. I want to check some new design products and fix our future order Program with the factory. The two companies are willingly ready to send Invitation in their Company Letter Head. I have my valid Passport. I Filled the Visa Form and attach 2 Passport size Photo. Please let me know if there any other documents or paper to be needed to grant my Visa Application.
Best regards,
