South Korea

South Korea offers American expats a compelling mix of modern infrastructure, world-class healthcare, and rich culture at a cost of living significantly lower than major US cities. Seoul ranks in Numbeo's 2025 cost index at roughly 62% of New York City, with one-bedroom city-center rents averaging around $900/month. The country ranks Level 1 (Exercise Normal Precautions) on the US State Department travel advisory as of 2025, and places in the top quarter globally on the Global Peace Index 2024. Healthcare is a major draw: South Korea's National Health Insurance Service covers residents (including long-term foreign residents after six months) at highly affordable rates, and the country consistently ranks in the top 5 worldwide on Numbeo's Healthcare Index. English proficiency is moderate — the EF English Proficiency Index 2024 classifies South Korea as 'low proficiency,' meaning expats outside Seoul and Busan expat hubs should expect a language barrier. Expat communities cluster in Seoul (Itaewon, Gangnam, Hannam-dong), Busan, and near US military installations. Visa pathways for Americans include the F-class long-term residency visas, the new Digital Nomad (F-1-D) visa launched in 2024, and investor/work routes, though a dedicated retirement visa does not exist.
