Sir,
I am a Indian citizen, our company is doing import business from china in a good scale so for that we have to go to china at many times a year.And also i have been in china more than 15 times from last 4 years. I always got visa through agent but this time he is saying that i can get only single entry visa in place of 6 months or 1 year multiple visa.So kindly suggest me that what i should do to get multiple visa.
