Entry day counted as day 1 (immigration practice). May vary by visa type/extension — verify the exact expiry on HiKorea or your ARC.
What this tool does
The Korea stay days calculator computes days stayed, expiry date, and days remaining from your entry date and allowed stay. It tracks 90-day visa-free entry and 30/60/180-day visas, warning you before you overstay. It follows the immigration practice of counting the entry day as day 1 to give an accurate expiry date.
Who uses this
- Track the 90-day visa-free expiry
- Check days remaining when planning departure
- Prevent illegal overstay in advance
- Identify when to apply for an extension
- Review cumulative stay after re-entry
How to use
- 1Enter your entry date (year/month/day) — the passport entry stamp date.
- 2Enter the allowed days or pick a preset (30/60/90/180). Visa-free is usually 90 days.
- 3See days stayed, expiry date, and days remaining. A red warning appears if you've overstayed.
Calculation method
Days stayed = (today − entry) + 1 (entry day included) Expiry = entry + (allowed days − 1) e.g. enter Jun 1, 90 days → Jun 1 is day 1, Aug 29 is day 90 (expiry) Days remaining = expiry − today Note: counting the entry day as day 1 is Korean immigration practice. Status changes may use a different basis.
Real examples
Example 1: Enter Jun 1, 90-day visa-free
Expiry Aug 29 (Jun 1 is day 1). On Jun 30 you've stayed 30 days, 60 remaining. Departing by Aug 29 is fine.
Example 2: Departing on the expiry day
Departing on Aug 29 (day 90) is valid. From Aug 30 it's an overstay. Departure must be within the expiry date.
Example 3: Overstay detection
Sep 1 is 3 days past expiry (Aug 29). A red warning shows. Overstay leads to fines and entry bans — depart and report immediately.
Stay & visa compliance checklist — avoid overstaying
Track your stay & expiry dates
- Know your exact permitted-stay end date (90 days visa-free, or the date printed on your ARC/visa) and set a calendar countdown.
- Apply to extend at least ~2 months before expiry (some statuses allow up to 4 months ahead) — never let the date pass (verify your window).
- Even one day past expiry counts as overstay — there is no grace period.
- Extensions can only be filed inside Korea (immigration office or HiKorea), never at an overseas embassy.
- If you change job, school, or visa status, file the change before your current authorization lapses.
Registration & reporting deadlines
- Register for an ARC within 90 days of entry if staying longer than 90 days.
- Report any address change (체류지 변경신고) within 14 days of moving, at immigration or your district (gu) office.
- Bring passport, ARC, the change form, and your lease (plus a residency-confirmation form if the home is in someone else's name).
- Report a lost or stolen ARC within 14 days at immigration or a police station.
- Late reporting can be fined up to ~₩1,000,000 (Immigration Act Art. 35) (verify current amount).
Re-entry, ARC carry & travel
- Carry your ARC at all times once registered — it is your legal ID in Korea.
- Before traveling abroad while waiting for your ARC, get a Re-Entry Permit (REP) — leaving without one can void your visa.
- For absences over ~1 year, apply for a Multiple Re-Entry Permit (valid up to 2 years) via HiKorea.
- Confirm your re-entry status before each international trip; an active ARC alone does not guarantee re-entry.
Stay within your visa's activity scope
- Student (D-2/D-4) and job-seeker (D-10) visas do NOT include automatic work rights.
- Get a part-time/activity permit (시간제취업 / 체류자격 외 활동허가) on HiKorea BEFORE working outside your scope.
- Don't start a job on a promise that 'the paperwork will catch up' — it's the worker, not the employer, who loses status.
- Working outside your scope is illegal employment — fines, refused extensions, cancelled status, and deportation can follow.
- When unsure of your visa's limits, check hikorea.go.kr or call the Immigration Contact Center 1345.
Frequently asked questions
Is the entry day counted as day 1?
Yes. In Korean immigration practice the entry day is day 1. Enter Jun 1 and that's day 1; 90-day visa-free expires on Aug 29 (day 90). This differs from interpretations that count the entry day as day 0.
How are the 90 days counted — is departure day included?
Departing by the expiry day (day 90) is valid. If expiry is Aug 29, departing Aug 29 is OK; Aug 30 is a 1-day overstay. Departing the day before expiry is the safe choice.
Can I re-enter immediately after 90 days?
Re-entry itself is possible, but repeated short in-and-out trips (border runs) can lead to entry denial. For long stays, get the proper visa (D/E/F).
What happens if I overstay?
Fines apply (by days/duration), and you may face entry bans or deportation. Voluntary reporting can reduce penalties — contact immigration before overstaying.
When do I apply for an extension?
Usually from 4 months before expiry, online via HiKorea or at an immigration office before expiry. Last-minute applications risk rejection or delay.
Can I use this as official proof?
For reference only. Your ARC, HiKorea stay information, and the immigration office are the official sources for exact expiry and status. Use this tool for self-checks.
