Korea Alien Registration Card Guide for Foreigners | ARC Application Step-by-Step | Expat Must-Have PDF

Here's the truth nobody tells you before you arrive in Korea: without an Alien Registration Card, you basically don't exist. No bank account. No phone plan. No apartment lease. No hospital registration. No internet installation. Nothing. Your passport alone won't cut it — Korea runs on this one small card, and you have exactly 90 days from entry to get it. Miss that window? You're already in violation.

The problem is, the process isn't hard — it's just confusing. Immigration office websites are mostly in Korean. Appointment slots fill up fast. You show up with the wrong photo size or a missing document, and you're sent home to start over. We've watched it happen to too many people.

This guide exists so that doesn't happen to you.

What's inside: → Who needs an ARC and who doesn't (visa type matters) → The 90-day rule — and exactly when your clock starts ticking → Complete document checklist: passport, visa, application form, photo specs (3.5×4.5cm), fee → How to book your Immigration office appointment (HiKorea walkthrough) → What to expect on the day — lines, waiting times, what they actually ask you → Processing time and how to pick up your card → What to do if you lose your ARC (reissue process) → The new mobile ARC — what it is, where it works, and where it still doesn't → How your ARC number connects to everything: banking, phone, hospital, delivery apps

This is the first card you need in Korea. Everything else depends on it. Get it right the first time.
