Korea Immigration Office & HiKorea Guide (2026)

General information for foreign residents · Last reviewed: June 2026

Almost every visa task in Korea runs through one place: HiKorea, the official immigration portal. Whether you're extending a visa, changing status, or registering, you'll usually start by booking a visit reservation or filing an e-Application there — and most offices no longer take walk-ins. This page explains honestly how HiKorea, the immigration offices, and the 1345 helpline fit together, and points you to the official sources for the final word.

⚠️ Office procedures, reservation rules, and which tasks are available online change. This is general information, not legal or immigration advice. Always verify the current process on the official Korea Immigration Service site hikorea.go.kr (or via the 1345 immigration helpline) before acting.

What HiKorea is for

HiKorea (hikorea.go.kr) is the official online portal of Korea's immigration services for foreign residents. It is where most people start an immigration task. The site is reported to support Korean, English, and Chinese. Treat HiKorea and the Korea Immigration Service as the authoritative source over any third-party guide — including this one.

1. Reserve an office visit

Most immigration and foreign resident offices require a reservation and do not accept walk-ins for most services. Use the "Reserve Visit" function on HiKorea and pick the office for your registered address.
Booking required

2. File an e-Application

Many tasks — such as some visa extensions and changes of status — can be submitted online through HiKorea's e-Application system without visiting in person.
Often online

3. Find your office by address

The office with jurisdiction over you generally depends on your actual residential address. HiKorea helps you select the correct one when booking.
Address-based

4. Get help on 1345

The 1345 immigration call center provides guidance on visas, reservations, and procedures, with multilingual support reported. Dial 1345 from within Korea (no area code).

How to book a visit reservation

Booking is the step most newcomers stumble on, so here's the honest shape of it:

StepWhat happens
Open HiKoreaGo to hikorea.go.kr and choose the "Reserve Visit" option
Member or non-memberYou can usually book as a HiKorea member or as a non-member
Pick the right officeSelect the office that serves your registered address
Choose the service categoryPick the booth/category that matches your task (e.g. residence-related)
Pick a slotAvailable slots can be limited — book early, and bring all required documents

The exact booking screens, available booth categories, and which services need a visit versus online filing change over time. Confirm the current steps on HiKorea or by calling 1345 — do not assume a remembered flow.

Which tasks use HiKorea

Most of the guides on this site route through HiKorea at some point. For example: filing a visa extension, a change of visa status, registering for your Residence Card (ARC), or applying for a re-entry permit. Whether each one is fully online or needs an in-person visit depends on the task — check on HiKorea.

Book early, act before deadlines

Because reservations can fill up and most offices don't take walk-ins, the safe habit is to book well before any deadline — especially extensions, which can usually be filed in advance. Letting a deadline pass risks an overstay, which is far more costly than booking early.

Travel tip, not visa advice: residents often keep a local eSIM or Korean number active so they can receive HiKorea verification texts and reservation confirmations — which are easy to miss without a working Korean number.
