I have travelled to China more than 30 times on Business Visa but still face difficulties for IL.
Myself Asif, Pak. national, living in Oman, from last more than 6 years. M working as electrical engineer in a company. My job is the import of electrical items from China (Inspection, material selection, doing OEM/ODM with Chinese companies, search suppliers, pricing, QC, packing etc.). I travel almost every month to China and till now I have travelled more than 30 times. I have multiple, 2 entry and single entry visas on my passports. Since last year the invitation letter is required from “Foreign Affairs Bureau, China which being frequent flyer is time taking, expensive and troublesome for my suppliers in China and myself even. The invitation letter is for single entry and every time they need to take and send to me. This is cutting my feathers day by day as I cannot execute my job responsibilities. Can anybody guide me how to get multiple entry invitation letter in this situation?? Thanks
