South Korea does not issue one document that updates immigration, health insurance, banks, phones, and traffic together. Build a folder where passport name, Residence Card number, Korean address, and phone number match, then work the chain in order. Korean-only counters are common: bureaucracy without Korean.
Which immigration records come first?
Confirm you hold the correct status of stay for what you will do. A tourist or visa-waiver entry is not a long-stay work or study plan.
If you intend to remain more than 90 days under a qualifying status, complete foreigner registration for the Residence Card through a HiKorea reservation at the immigration office for your address. Bring passport, photo, fee, and place-of-stay evidence.
Keep that address current. After registration, report each new place of stay within 15 days through eligible HiKorea online filing or the office responsible for the new home: register address. Lease and deposit steps sit in housing answers, but immigration still needs occupancy proof.
Which steps unlock health, money, phone, and driving?
Eligible residents enrol in National Health Insurance Service (NHIS) cover under employee or local-subscriber rules after status and registration timing allow it: choose health insurance. Keep private cover active until public enrolment is real.
Open a Korean bank account when the branch accepts your identity and purpose pack. Many newcomers start with transaction limits until payroll, rent, or utility evidence appears: open a bank account. A real-name Korean mobile line usually needs the Residence Card and matching spelling for carrier registration: get a mobile phone.
If you will drive, check KoROAD exchange rules early. Reciprocal-country licence swaps differ from International Driving Permit short use: convert a driving licence. Moving with a dog or cat is a separate Animal and Plant Quarantine Agency (QIA) entry file: bring pets.
Common misconceptions
The Residence Card does not automatically enrol you in NHIS, open a bank account, or transfer a foreign licence. Each office still runs its own checklist.
Reporting a lease to your landlord also does not replace the immigration place-of-stay report. Missed address deadlines can create fines separate from housing disputes.
Summary
Treat Korean post-move paperwork as a sequence: correct status, Residence Card, address reports, then NHIS, banking, phone, and driving. Match every form to the same Korean address and romanised name, and use HiKorea or 1345 when the next office is unclear.
