Korea Alien Registration: 90-Day Deadline, HiKorea Booking, Fines

Image generated with ChatGPT for illustration purposes.

Last checked: 2026-09-25 (KST) · Sources: Enforcement Rule amendment of September 15, 2026, with its addenda, Korea Immigration Service fee notice of December 13, 2024, Korea.kr on the mobile registration card, January 9, 2025 · What changed recently: a correction. The first version of this post said the September 15, 2026 change to fee payment took effect that day. The amendment's own addenda delay that article by one year, to September 2027, and the card fee stays cash-only even then. Details under the fee section.

If you entered Korea this summer on a student or work visa, the calendar is now doing something quiet and important: the 90-day registration window that opened on your arrival day is closing. For an August 24 arrival, day 90 falls on November 21. For a September 1 arrival, it is November 29.

Blog guides tend to say "register within 90 days or pay a fine" and stop there. This post goes one layer down, to the law itself. It is built from the Immigration Act, its Enforcement Decree and its Enforcement Rule as served by the Korea Ministry of Government Legislation on September 18, 2026 (KST), plus the visit-reservation notice on HiKorea, the government's immigration portal. Checking the statute rather than summaries turned up three things the summaries leave out: the booking rule that moves your practical deadline earlier, the exact fine scale for late registration, and a September 15, 2026 amendment to how immigration fees are paid.

It explains the published rules and where they sit. For a question about your own file, the Immigration Contact Center answers on 1345.

Who has to register, and by when

Article 31(1) of the Immigration Act is short. A foreign national who intends to stay in Korea for more than 90 days from the date of entry must register with the head of the immigration office that has jurisdiction over their place of stay, within 90 days of entry.

Three groups are exempt under the same paragraph:

1. Staff of foreign embassies, consulates and international organizations in Korea, and their families
2. People who hold privileges and immunities similar to diplomats or consuls under an agreement with the Korean government, and their families
3. People invited by the Korean government who fall under a Ministry of Justice ordinance

Two further paragraphs change the clock for people who are already inside Korea:

• Article 31(3): if you are granted a status of stay in Korea (for example, a child born in Korea) and will stay more than 90 days from that date, you register at the time the status is granted.
• Article 31(4): if you receive a change-of-status permit and your stay will run past 90 days from entry, you register at the time the change is approved.

That second point catches people who arrive on a short-term status and switch to a long-term visa inside Korea. For them there is no separate 90-day window after the switch; registration is tied to the permit itself.

For children, Article 33(1) lets the office skip issuing a card to anyone under 17. When that person turns 17, Article 33(2) gives them 90 days to apply for the card.

Counting the 90 days

The statute says "within 90 days from the date of entry." Korean general law on periods has its own rules on whether the first day counts, and this post does not try to settle how an immigration office applies them to your file. The safe reading is to treat your entry day as day 1:

Entry date	Day 90 (entry day counted as day 1)
August 24, 2026	November 21, 2026
September 1, 2026	November 29, 2026

If you plan around that date, a one-day difference in counting can only work in your favour.

The HiKorea booking rule moves your real deadline

Visits to immigration offices are booked through HiKorea's visit reservation page, and the Jung-gu District Office's English guide tells new residents to reserve there before going to the office. The reservation page shows a list of cautions before it lets you book, with separate buttons for member and non-member bookings. Translated from the Korean text, the ones that matter for registration say:

• Book a date that falls before the end of your permitted stay or before the legal reporting period ends. The notice warns that visiting after that period has passed exposes you to a penalty (범칙금) or an administrative fine (과태료).
• If no bookable date exists inside your legal period, visit the office that has jurisdiction before the period ends.
• A reservation is only a booking for a visit date. It is not the filing of your application.

The third point is the one that changes the math. Holding a reservation for day 95 does not stop the clock on day 90, because nothing has been filed until you are at the counter. Your working deadline is therefore the last date with an open slot before day 90, and only your local office's calendar can tell you when that is. Booking in your first weeks in Korea, not your last, is the way to keep that date comfortably early.

Practical order of operations:

1. Get a place to live and the paperwork that proves it before you book (see the document list below).
2. Book on HiKorea as early as you can.
3. If the first open slot is after your day 90, do not wait for it. The notice tells you to go to the office before the deadline.

The same page warns that booking slots with another person's passport or registration number can lead to prosecution, with penalties it states as up to 5 years in prison or a fine of up to 50 million won under the Personal Information Protection Act and the Criminal Act. It also says the Ministry of Justice checks the IP addresses used for bookings, and that bookings held this way will be referred to investigators if they are not cancelled.

What to bring

Article 40 of the Enforcement Decree requires an application form, your passport and "other documents set by Ministry of Justice ordinance." Those documents sit in Appendix 5-2 of the Enforcement Rule, which has a row for alien registration under every status of stay.

Common to everyone registering:

• Application form (the integrated application form used for immigration services)
• Passport
• One passport-type photo, 3.5 cm × 4.5 cm, taken within 6 months, face length between 2.5 cm and 3.5 cm, plain or white background, no border, facing forward, no sunglasses or hat covering the face (medical exceptions apply)
• A document proving your place of stay (체류지 입증서류); the appendix does not list which documents qualify, so ask your school, employer or the 1345 line what your office accepts

Extra rows for three common statuses:

Status	Extra documents for registration (Appendix 5-2)
D-2 (student)	Certificate of enrollment; health certificate
D-4 (language training at a university institute)	Certificate of enrollment; health certificate
E-2 (foreign language instructor)	Employer's business registration certificate; medical check-up report including a drug test, from a hospital designated by the Minister of Justice (not required for teachers recruited through Ministry of Education or provincial education office programs for schools)

The appendix also states that documents issued abroad need an apostille or a consular confirmation from a Korean mission, and that originals must be presented. Where the office is able to check a document through government data sharing, the office verifies it instead of asking for a copy, unless you refuse consent.

The government's own EasyLaw guide for foreign students lists the same D-2 set: passport, one photo, proof of enrollment, proof of residence and a medical certificate.

The fee, and a September 2026 change in how you pay it

Article 72, item 10 of the Enforcement Rule sets the fee for issuing or reissuing an alien registration card at 35,000 won.

Not every official page agrees. The Jung-gu District Office's English guide still lists 30,000 won, alongside a processing time of about four weeks. The gap has a dated cause: the Korea Immigration Service's notice of December 13, 2024 raised the fee "(현행) 3만 원 ➟ (인상 후) 3만 5천 원" from January 1, 2025, because the new card carries an IC chip. The district page predates that. Cards issued before 2025 stay valid without replacement.

Pay the card fee in cash. Article 73 of the Enforcement Rule, on how fees are paid, was amended on September 15, 2026, and the amended text on the government's law site already lists credit and debit cards and electronic payment for immigration fees. But the amendment's addenda say 「제73조의 개정규정은 공포 후 1년이 경과한 날부터 시행한다」: the Article 73 change takes effect one year after publication, in September 2027. And even in the new text, the registration-card fee is the one exception, payable only in "현금 또는 현금 납입을 증명하는 증표" (cash or proof of a cash payment). (Correction, September 25, 2026: the first version of this post read the consolidated text and said the change took effect on September 15, 2026. I traced it back to the addenda, which say otherwise.)

The registration itself is fast once you are at the counter. The government's service portal (Gov.kr) page for alien registration gives the processing time for alien registration as 「즉시(근무시간 내 3시간)」, immediate, within three working hours; the plastic card is produced and delivered afterwards, and the four-week figure on the district page is the only published estimate found for that.

Article 33(6) of the Act also allows a mobile alien registration card with the same legal effect as the plastic card. Issuance began on January 10, 2025, for "14세 이상 모든 등록외국인", every registered foreigner aged 14 or over, through the government's Mobile ID app. There are two ways in: tap the IC chip of your plastic card with the phone, or scan a QR code at an immigration office. The IC route lets you reissue it yourself after changing phones; the QR route means another office visit.

What happens if you are late

The criminal provision

Article 95, item 7 of the Act lists "a person who violates the registration duty under Article 31" among offences punishable by imprisonment of up to 1 year or a fine of up to 10 million won. Blog posts that stop at this line make late registration sound like a criminal trial. The Act itself provides a second route.

The notice-of-penalty route

Article 102 lets the head of an immigration office, once an offence is established, issue a written notice ordering payment of an amount equivalent to a fine, called 범칙금. Article 102-2 allows paying it by credit or debit card. Article 103 says the amounts are set by Ministry of Justice ordinance, and lets the Minister waive the notice after considering age, circumstances, motive, results, ability to pay and similar factors.

The ordinance is Article 86 of the Enforcement Rule, which points to Appendix 7. Checking the text of Appendix 7 (last revised January 23, 2026), row "보" covers breach of the Article 31 registration duty, and the amount scales with how long the breach has lasted:

How long the registration duty has been breached	Standard amount
Under 1 month	200,000 won
1 month to under 3 months	500,000 won
3 months to under 6 months	1,000,000 won
6 months to under 1 year	2,000,000 won
1 year to under 2 years	5,000,000 won
2 years or more	10,000,000 won

Two rules sit around this table:

• Article 86(2): the office head may reduce or increase the standard amount by up to half, considering age, circumstances, motive and result, ability to pay and the number of prior violations.
• Article 86(3): with the Minister's approval, an office may set an amount outside these standards, including a full waiver under Article 103(2).

So a student who registers two weeks late faces a standard amount of 200,000 won, which the office can move between 100,000 and 300,000 won. Someone discovered after 14 months faces a standard of 5 million won. Article 102(3) adds that if an office judges the case serious enough to warrant imprisonment, it must file a criminal complaint instead of issuing a notice.

Recent amendments checked for this post

Checking only the rules above would miss changes that happened nearby, so each instrument's latest amendment was also read:

Instrument	Latest amendment	Effective	Touches registration?
Immigration Act	Act No. 20992, July 22, 2025	January 23, 2026	No. Creates the seasonal-worker program and bans unauthorized recruitment
Enforcement Decree	Presidential Decree No. 36673, September 15, 2026	September 15, 2026	No. Adds social-integration courses, widens F-1 household helper eligibility, widens H-2 work scope
Enforcement Rule	September 15, 2026	September 15, 2026; the Article 73 payment change one year later (September 2027)	Yes, indirectly. Card and electronic payment for immigration fees, except the registration-card fee, which stays cash
Rule, Appendix 7 (fine scale)	January 23, 2026	as published	Contains the registration fine row

None of these changed the 90-day rule itself or the registration fine amounts in September 2026.

What to do next

Your target date is the last open HiKorea slot before day 90. If that day is inside the next month, the next step is a short sequence: secure proof of residence, collect the status-specific documents in the table above, and book on HiKorea today. If the first slot falls after your deadline, go to your immigration office before the deadline, as the HiKorea notice instructs. If you have already missed it, registering sooner keeps you in a lower band of the fine table, since the amount rises with the length of the breach.

Readers arriving from a visa-free country for a short visit before a longer stay should also check whether they need a K-ETA; the rules are in K-ETA Temporary Exemption Extended Through 2026. If you came for work in the data center build-out, Korean Data Center Jobs: What the Training MOUs Leave Out covers what the hiring agreements do and do not promise.

What this post could not confirm

• How a specific immigration office counts the first day of the 90-day period in practice
• Current wait times for HiKorea registration slots at individual offices
• The current delivery time for the physical card; the only published figure found, about four weeks, comes from a district office page that also shows the pre-2025 fee
• Whether a registration receipt lets you leave and re-enter Korea before the card arrives; no official page read for this post says
• Whether, and how much, a registration penalty is weighed in a later visa extension or change of status; the provisions read for this post do not say

Rules and appendices can change with little notice. Checking the original on the Ministry of Government Legislation site before relying on a number is worth the time.
