What is G-1-8?
The manual does not contain a standalone definition table for G-1-8. The single confirmed appearance is in the D-2 (유학) status-change eligibility rule: long-term legal stayers in Korea are generally allowed to change status, EXCEPT holders of 기술연수(D-3), 계절근로(E-8), 비전문취업(E-9), 선원취업(E-10), 인도적체류허가자(G-1-6), and 'other G-1' status holders EXCLUDING 장기체류 아동(G-1-8, 13, 14). In other words, G-1-8/13/14 (grouped together as '장기체류 아동' / long-term-staying children) are carved OUT of the general G-1 restriction on changing to D-2 — meaning they are permitted to change status to Student (D-2), unlike most other G-1 subtypes.
