The F-1 visa (방문동거 — visit and cohabitation) covers a broad range of family-related long-stay situations that do not fit the narrower F-3 (dependent companion) or F-6 (marriage migrant) categories. It is issued to relatives visiting or cohabiting with Korean residents: parents accompanying children in Korean schools, parents of outstanding talent or investors, domestic helpers of foreign diplomatic staff or high-value investors, and others with compelling personal circumstances requiring an extended stay without independent employment. F-1-D (the digital nomad visa) is a separate sub-type under the F-1 code but has its own dedicated page. F-1 holders may not engage in independent paid employment.
Notable sub-type added March 2025 — F-1-52: issued to children born from a marriage migrant's prior relationship (결혼이민자의 전혼관계 출생자녀). This allows a foreign national currently residing in Korea as an F-6 marriage migrant to invite their child from a previous relationship (a child not born to the current Korean spouse) to live in Korea. The F-1-52 sub-type was added to the official immigration guidelines effective 17 March 2025.
