What is G-1-1?
G-1-1 covers foreigners who are pursuing an industrial-accident (산재) compensation review or re-examination claim, or who are hospitalized/undergoing medical care for a work injury after receiving 요양승인 (care approval) from the Korea Workers' Compensation & Welfare Service (근로복지공단), including those being treated for after-effects. It also covers the family (spouse and direct lineal relatives) of such a person. The manual lists this as item 1 in both the initial-issuance table and the extension table, and the code is consistently attached to the same heading in both places.
