Over 150,000 U.S. citizens reside in South Korea (ROK), forming one of the largest American expatriate populations in Asia. Their presence stems from historical, economic, and personal factors spanning seven decades.
The 1950-1953 conflict brought hundreds of thousands of U.S. service members to Korea. Many remained after the armistice—some marrying Korean nationals, others continuing military careers at bases like Camp Humphreys (largest overseas U.S. base), Osan, and Kunsan. Today, ~28,500 U.S. troops are stationed in ROK, with families and civilian contractors adding to the community.
Corporate Careers: Korea's transformation into a tech/manufacturing powerhouse (Samsung, Hyundai, LG, SK) attracts American professionals in engineering, finance, and management. English Education: Hagwons (private academies) and public schools hire thousands of native English teachers annually, offering competitive salaries, housing, and airfare. Entrepreneurship: Seoul's startup ecosystem, government incentives, and digital infrastructure draw founders.
Language barrier, cultural adjustment, visa complexities (F-series visas for long-term stay), and distance from U.S. family remain considerations.
