Dear sir/madam,

I hold a passport from Korea and a passport from the Netherlands and would like to go to China for study/tourism for about 1 year.
I was wondering if it is possible to get a multiple entry visa for 6/12 months in Seoul. I have several used T visa's to China in my Dutch passport. Do I need to show this when applying for my visa on my Korean passport to improve my chances for a longer stay?

Kind regards,

Jae Lankwarden
