I did not have a problem getting a Chinese visa in Seoul. My ARC expires 8-24.
The problem that I'm having is that the tourit agency got me a single entry visa and I wanted multiple.

The fee should be 160,000 won, which includes the tourist agency fee.
They are asking for 190,000 for something I did not order.

They tried to tell me that only Koreans can get a multiple visa to China. I check this site and found that to be false.
Has anyone had this type of problem? They are still holding my passport hostage. Thank god that I haven't bought the tickets for China yet.
