We want to vist Korea (starting in Busan) in late June /July. estimated stay 2-3 weeks ,but longer if we like it (coming from Thailand ). I have German Passport ,my wife Thai Passport . It would be easiest for us to travel with a carrier such as Air Asa ,i which will allow to buy just a one way ticket . Then we can stay as long or short as we want to and buy another one weay to retuen.
Will we be able to enter the contry with a one way ticket or do we have to show return travel plans ?
