What visa do my spouse and children need to live with me in Korea on an E-7 visa, and how do I sponsor them?

Your spouse and unmarried minor children can join you on an F-3 dependent visa, which is tied to your E-7 status. You sponsor them by showing proof of your relationship (marriage and birth certificates, apostilled and translated), your employment and income, and housing, applying at a Korean consulate in their country or changing status at immigration if they're already here. F-3 holders can live and study in Korea but generally can't work without separate permission. Income and space requirements apply, so check the exact document list on HiKorea or with 1345 before filing.
