Moving to Korea: Essential Korean for Expats
Alien Registration Card (외국인등록증)
The 외국인등록증 (oeugukineungnokjeung, alien registration card) is the foundational document for any foreigner living in Korea for more than 90 days. Applications are submitted at the local Immigration Office (출입국·외국인청, chulipguk oegukin-cheong) within 90 days of arrival. You will need your passport, a completed application form (신청서, sincheongseo), a passport-sized photo, and any visa or status documentation. The card serves as your primary identification for opening bank accounts, signing leases, registering for national health insurance, and accessing government services. Key vocabulary for the process: 체류자격 (chelyujagyeok, visa status), 등록번호 (deungrokbeonho, registration number), 주소 (juso, address), and 체류기간 (chelyugigan, period of stay). If your Korean is limited at the immigration office, the phrase 「영어로 도와주실 수 있나요?」 (yeong-eoro dowajusil su innayo?, 'Can you help me in English?') will usually direct you to an English-speaking staff member.
Finding Housing in Korea
Korean housing has a unique rental system called 전세 (jeonse), where tenants pay a large lump-sum deposit (often 50–80% of the property value) in exchange for no monthly rent — the landlord uses the deposit as an investment. More accessible for most expats is 월세 (wolse), the standard monthly rent system with a smaller deposit (보증금, bojeunggeom, typically one to three months' rent) plus monthly rent (월세, wolse). Real estate agents are called 부동산 (budongsan) — the same word as the shop sign you will see everywhere. Essential questions include: 「보증금이 얼마예요?」 (What is the deposit?), 「월세가 얼마예요?」 (What is the monthly rent?), 「관리비가 따로 있어요?」 (Is there a separate maintenance fee?), and 「외국인도 계약할 수 있어요?」 (Can foreigners sign a lease?). Many landlords in Seoul's Gangnam or expat-heavy areas are experienced with foreign tenants; those in smaller cities may require an additional guarantor or higher deposit.
National Health Insurance
Korea's National Health Insurance Service (국민건강보험공단, gungmin geongang boheom gongdan) automatically enrolls employed foreigners via their employer; self-employed or dependent foreigners must register within 14 days of obtaining their alien registration card. With insurance coverage, you typically pay 20–30% of medical costs at clinics and hospitals. For a regular clinic visit (병원, byeong-won), key phrases include: 「어디가 아프세요?」 (Where does it hurt? — what the nurse will ask), 「배가 아파요」 (I have a stomachache), 「열이 나요」 (I have a fever), 「처방전 주세요」 (Please give me a prescription), and 「약국이 어디예요?」 (Where is the pharmacy?). Most clinics in Korea work on a walk-in basis; large hospitals require advance appointments (예약, yeyak). Emergency services are reached by dialing 119; the phrase 「구급차 불러주세요」 (Please call an ambulance) is essential.
Korean Banking Apps
Korean banks have among the most feature-rich mobile banking apps in the world, but setting them up as a foreigner requires patience and specific preparation. To open an account you typically need your alien registration card, passport, Korean phone number, and a seal or signature consistent with your ID. Major banks expats commonly use include KakaoBank (카카오뱅크, entirely app-based and foreigner-friendly), Shinhan Bank (신한은행), Woori Bank (우리은행), and KEB Hana Bank (하나은행). Key banking vocabulary: 계좌 (gyejwa, bank account), 이체 (iche, transfer), 잔액 (janaek, balance), 비밀번호 (bimilbeonho, PIN/password), 공인인증서 (gonginincheungseo, public certificate, required for many banking transactions), and 해외 송금 (haoe songeum, international wire transfer). KakaoBank's app is available in English and has simplified the account-opening process significantly for foreigners compared to traditional banks.
Transport: T-money Card and Subway
The T-money card (티머니 카드) is a rechargeable transit card used on Seoul's subway, buses, and taxis, and accepted in convenience stores across the country. It offers a small discount per ride compared to cash fares and eliminates the need to buy individual tickets. Cards are purchased and recharged at convenience stores (편의점, pyeon-uijeom) or subway station vending machines. Key subway vocabulary: 지하철 (jihacheol, subway), 환승 (hwanseung, transfer), 출구 (chulgu, exit), 승강장 (seunggangjang, platform), 막차 (makcha, last train), 첫차 (cheotcha, first train), and 잠시 후 문이 닫힙니다 (jamsi hu muni dachim nida, 'Doors will close shortly' — the announcement you will hear constantly). If you are lost on the subway, the phrase 「이 역이 어느 역이에요?」 (I yeogi eoneumnyeogi eyo?, 'Which station is this?') and showing your destination written in Korean will almost always prompt helpful assistance from nearby passengers.
Workplace Honorifics
Korean has an elaborate speech level system that is deeply embedded in professional culture. The two most important levels for workplace use are 존댓말 (jondaemal, formal/polite speech) and 반말 (banmal, informal speech). In a Korean workplace, always default to 존댓말 with colleagues unless explicitly invited to speak informally. The -습니다/-ㅂ니다 (formal polite) endings are used in presentations, official communications, and formal meetings. The -아요/-어요 (informal polite) endings are standard in day-to-day office conversation. Critical workplace phrases include: 「수고하셨습니다」 (You've worked hard — said at end of day or after completing a task), 「잘 부탁드립니다」 (I look forward to working with you — said when starting a new project or meeting someone new), 「확인해 드리겠습니다」 (I will check/confirm that for you), and 「죄송합니다, 다시 한번 말씀해 주시겠어요?」 (I'm sorry, could you say that again?). Bowing slightly while greeting colleagues and using both hands when receiving business cards are non-verbal aspects of Korean workplace etiquette equally important as the language itself.
