I have never stayed in a country long enough where I've HAD to leave to get my visa renewed. My outbound flight is on the 22nd of December which is 2 days before my visa expires. I was just wondering, what would happen if my outbound flight was on the 24th and say, all flights were cancelled that day for some reason like weather or a KE pilots strike. Who knows but in any case, I wouldn't be able to leave Korea. Just curious.
