i understood extensions are possible only for certain countries (not including mine).
ok, so perhaps there is no strict guidelines to as what are the possibilities. also forexample if japanese tourists travel to europe, they can stay 3months at a time and re-enter once per year for another 3month stay. no questions asked, that is simply the rule.
so yeah perhaps a passport full of korea stamps is not such a good idea
maybe travel to other countries, stay longer periods away, make up good excuses..
that embassy website is not available in english. well im sure atleast one time the korea trip has to work, so i can go ask them in person.
would like to hear more from people with actual experience!
