Korean medical translation — serving 1.1 million US Korean speakers
With 1.1 million Korean speakers in the United States — concentrated in California, New York, New Jersey, and Texas — the demand for qualified Korean medical interpreters is both a legal requirement and a patient safety imperative. Section 1557 of the Affordable Care Act mandates free qualified interpreters for all LEP patients in federally funded healthcare settings.
Korean medical translation also serves South Korea's advanced pharmaceutical and medical device industry. South Korea's MFDS (Ministry of Food and Drug Safety) requires Korean-language documentation for all pharmaceutical products and medical devices sold in Korea. South Korea is a global leader in medical devices, cosmetics, and biopharmaceuticals.

Korean legal translation — navigating Korea's civil law system
South Korea operates under a civil law system influenced by German law, with significant differences from US common law.

Day Translations' legal team includes specialists in Korean corporate law, patent law, and cross-border US-Korea legal matters.

Business & localization
South Korea: the world's 13th largest economy and a global technology leader
South Korea is the world's 13th-largest economy with a GDP of $1.7 trillion. South Korea is home to some of the world's most innovative companies — Samsung, LG, Hyundai, Kia, SK Group, POSCO — and is a global leader in semiconductors, electronics, automotive, and shipbuilding. South Korea's cultural exports — K-pop, K-drama, K-beauty — have created a global Korean Wave (Hallyu) with unprecedented reach.
Korean localization requires careful attention to Korea's honorific system (존댓말/jondaemal). Korean has multiple speech levels — formal, informal, polite, and intimate — that must be matched to the audience and context. Korean text can expand or contract significantly compared to English. Day Translations' Korean localization team includes in-country reviewers in Seoul and Busan.
