Hi, I'm currently studying in Beijing but will have a month and a half off starting in May. I'd like to visit some friends in Korea in that time, return to China travel, visit Hong Kong to see some other friends and then return to Beijing in June for school. I'm going to need a dual-entry to do this... I tried to get one the first time I came to China but they wouldn't give me one so I'm concerned that that might happen again.

Does anyone have any idea of how likely it is I can get a dual-visa from Korea? (I'm a Canadian). I will also have an official letter from the institution I'm studying at to verify what I'm doing in Beijing.
