1. 🚇 T-money Card: Korea's Daily Transit Survival Tool for F-4 Holders On your first day navigating Seoul's subway as an F-4 visa holder, you'll discover that Korea's public transportation runs on a fundamentally different payment ecosystem than Western countries: cash is increasingly unwelcome on buses (many routes refuse it entirely), single-journey tickets waste time and money compared to rechargeable cards, and the entire system rewards strategic card usage through transfer discounts that can cut your monthly transit costs by 30-40% if you understand how they work. The T-money card—a small rechargeable smart card costing 3,000-4,000 won—is the universal payment method accepted across Seoul's subway, nationwide buses, taxis, and even convenience stores, making it the single most practical purchase F-4 holders make upon arrival after securing a SIM card and accommodation .

1. 🚨 Korea Jeonse Deposit Scams: The $200K Mistake F-4 Holders Make Every year, hundreds of foreigners in Korea—including F-4 visa holders who wired their life savings from overseas—lose six-figure jeonse deposits to sophisticated rental scams that exploit the unique vulnerabilities of Korea's unusual housing system. Unlike monthly rent contracts in Western countries where you pay gradually over time, Korea's jeonse system requires upfront deposits ranging from $150,000 to $500,000 that landlords theoretically return at lease end, making it a catastrophically attractive target for fraud schemes involving fake landlords, overleveraged properties with hidden mortgages, and bankruptcy traps that leave tenants fighting banks for years to recover pennies on the dollar . The 2026 reality: Korea's jeonse market contains systematic risks that even Korean nationals struggle to navigate, and F-4 holders face compounded danger because they often lack the Korean...
