The tricks the forms don't tell you
Everything here is official — it's just not written anywhere obvious.
Sending money home from Korea
Banks vs licensed apps, the January 2026 rule changes, and how to stop losing money in the exchange rate.
Read the guide →1Call 1345 and ask for your checklist by email
The Immigration Contact Center (dial 1345 in Korea, +82-1345 from abroad) can review your exact situation — nationality, current visa, income type — and will usually email you the complete document list for your case. It's the single best way to handle exceptions, and almost nobody knows you can ask. One catch: all 19 languages run weekdays 9:00–18:00; evenings until 22:00 are Korean, English and Chinese only.
2HiKorea reservations: midnight is your friend
Visit reservations at hikorea.go.kr often look fully booked for weeks. Cancelled slots are released back into the system — checking right after midnight (and again early morning) regularly finds openings. You can also try any office within your jurisdiction, not just the closest one.
3Many extensions don't need a visit at all
HiKorea's e-Application (전자민원) handles several extensions and address changes fully online. Before fighting for a reservation, check whether your task is on the e-Application list.
4The 90-day rule is the one deadline that bites
Whatever visa you arrive on, if you stay more than 90 days you must apply for a Residence Card within 90 days of entry. Missing it means fines that scale with the delay. Book HiKorea in your first week — the appointment itself can be weeks out, and having the reservation counts for your timing.
5Bring more than the list says
Officers can request extra documents on the spot. The cheap insurance: passport copies, extra photos, your lease, bank app logged in, and your employer/school contact reachable by phone during your appointment.
6Can't make phone calls? You're not stuck
Before you fly: email the Korean embassy or consulate covering your area — pre-departure document questions are exactly their job. Already in Korea without a working SIM: HiKorea's online inquiry answers in writing, your school's international office will often call 1345 for you, and from any phone abroad +82-1345 reaches the same center. Nothing in the visa process actually requires you to make a call.
7Your first weeks in Korea run on your passport
Until your Residence Card arrives (2–6 weeks after applying), most banks won't open an account and carriers won't sell you a postpaid plan — that's normal, not a mistake. Bridge it with a prepaid/tourist SIM (passport only, sold at airports and convenience stores) and ask your school or employer which nearby bank branch is used to foreigners — some open accounts on a passport alone.
8Health insurance enrolls you automatically at 6 months
Stay past 6 months and you're enrolled in National Health Insurance automatically — students included — with a monthly bill to match. It's not optional and not a scam: coverage is genuinely good and students pay a reduced rate. The first surprise invoice catches almost every long-term arrival; now it won't catch you.
