Here's a step-by-step on opening a bank account in Korea. The most foreigner-friendly banks are Hana Bank, which has excellent English service and a global counter, KEB Hana with multi-language support, and Shinhan Bank, which has a good mobile app with an English UI. You'll need your passport, your Alien Registration Card (ARC), proof of address such as a utility bill or lease contract, and a phone number registered in Korea. A few tips: visiting a branch near a university campus often means better English support, most banks require you to already have an ARC before opening an account, and registering for internet banking may need a separate visit.
