After moving in Korea, what was the fastest way you got your ARC address updated properly?
I keep seeing people get stuck on the same part. One person says just go to the 주민센터, another says do it through HiKorea, another says bring the contract and do both because something always gets missed. If you moved recently in Korea, what actually worked with the least back and forth? Mostly asking about the practical version, not the ideal version on paper.
