Hi, My Nationality is Indian. I am working in Shanghai China for last 4 years . Due to business meeting, I have to travel to Dhaka in Bangladesh. I need to apply for the M type. Pls advise the fee for the Indian National for Multiple Entry type? I tried to check online but the information is not mentioned. Also , pls advise if I need to personally come to Beijing to apply?
Thanks
