At some point after you settle in Korea, the message arrives. A friend from home, or a parent, or a sibling, says they are thinking of visiting. And you realise that everything you know about living here — your residence card, your bank account, your transit card — tells you almost nothing about how a visitor gets in.
The information gap is real. Guides written for tourists assume nobody in Korea is helping them. Guides written for residents assume you are the one arriving. Nobody writes for the person in the middle: you, holding a residence card, trying to work out what your guest needs and what you are supposed to send them. This guide is about hosting visitors in Korea from the host’s side.
TL;DR
- Start by working out which of three groups your friend is in. Visa-free and K-ETA-exempt, visa-free but needs K-ETA, or needs an actual visa. Everything else follows from this.
- Many nationalities currently need neither a visa nor K-ETA. The Ministry of Justice extended a temporary K-ETA exemption through 31 December 2026.
- But exempt travellers must submit the e-Arrival Card. K-ETA holders are exempt from it — so skipping K-ETA means doing the arrival declaration instead.
- That is a real choice, not a formality. One is free but repeated every trip; the other costs a fee and lasts years.
- If your friend needs a visa, they apply in their own country — not in Korea. You prepare documents here and send them over.
- Your residence card is one of those documents. For family visit applications, consulates require copies of both sides.
- Start six to eight weeks out. Visa processing alone can take three to four weeks.
- Your guest can do things you cannot — tax refunds, tourist rail passes, tourist-only cards. Tell them before they arrive, not after.
First, Find Out Which Group Your Friend Is In
Before you research anything else, establish this. It determines whether you are sending documents to another country or just sending a link.
Group 1 — Visa-free, and currently exempt from K-ETA. They book a flight and go. No advance authorisation. This covers a large share of the passports most likely to be visiting you.
Group 2 — Visa-free, but K-ETA required. They apply online before boarding, pay a fee, and get a multi-year authorisation.
Group 3 — A visa is required. They apply at a Korean embassy or consulate in their own country, and you have paperwork to do.
The single question that sorts them: what passport does your friend hold? Not where they live, not where they are flying from. Nationality.
There is no shortcut around checking this properly, because the rules are country-specific and they change. Our guide to Korea’s government websites covers which official site answers which question, and the short version is that the visa portal handles visa questions and the K-ETA site tells you whether K-ETA applies. Both end in .go.kr. Anything that does not is not the government.
Group 1: Visa-Free and Exempt From K-ETA
This is the easiest case and also the one where your friend is most likely to be misinformed, because plenty of travel sites still say K-ETA is mandatory.
The Ministry of Justice introduced a temporary K-ETA exemption to support tourism, and has extended it repeatedly. The current extension runs from 1 January 2026 through 31 December 2026, and it applies to the countries already covered — the United States included. Korean embassies and consulates have published this consistently.
Two things worth knowing that almost nothing in English mentions:
The exemption is checkable. If your friend starts a K-ETA application, the system shows an exemption notice when it recognises their nationality. So there is a way to verify their own status without trusting a blog.
There is a separate age-based exemption. Among nationals of visa-free countries, travellers aged 17 or under and 65 or over are outside the K-ETA requirement regardless of the country-based measure. This one is easy to miss, and it matters if you are hosting a parent or bringing a younger sibling.
Warning worth passing on directly: there is active misinformation circulating that US citizens need K-ETA from January 2026. Korean embassy notices say the opposite. If your friend has read otherwise, send them to the official notice rather than arguing about it.
What has not been decided: whether K-ETA becomes mandatory again after 2026. No official announcement exists either way. If your friend is travelling in early 2027 or later, this needs rechecking rather than assuming.
The Decision Nobody Explains: K-ETA or the e-Arrival Card
Here is the mechanic that connects the two systems, and it is the most useful thing in this guide.
Since 1 January 2026, foreign visitors entering Korea submit an e-Arrival Card — the digital replacement for the paper form you used to fill out on the plane. It is submitted online, it is free, and it can be filed within three days before arrival.
But holding a valid K-ETA exempts your friend from the arrival card.
Put those two facts together and an exempt traveller has an actual choice:
Option A — skip K-ETA, submit the e-Arrival Card. Free. Done shortly before each trip. Repeated every single visit.
Option B — apply for K-ETA voluntarily, skip the arrival card. Embassy notices confirm that exempt nationals may still apply if they want the benefits, and that the application fee applies. A K-ETA is generally valid for around three years, and can be used for multiple entries within that period.
So the honest advice depends on your friend, not on which is objectively better:
- One visit, probably not returning soon → Option A. Do not pay for something you use once.
- Someone who will come back — a parent visiting yearly, a partner doing long-distance, a colleague on repeat business trips → Option B is worth pricing out. Pay once, then walk through immigration for years with nothing to file.
No competing guide frames this as a decision, because most of them have not noticed that the two systems interact.
One caution. Do not tell your friend to skip the arrival card unless they actually hold a K-ETA. Being eligible for K-ETA is not the same as having one. The exemption from the arrival card attaches to holding a valid authorisation.
Group 2: Visa-Free but K-ETA Required
If your friend’s nationality is not covered by the temporary exemption, K-ETA is the step before boarding — not on arrival, not at the airport. Airlines check it.
What you need to tell them:
- Apply on the official K-ETA site or app, and nowhere else. Third-party agencies charge markups for filling in the same form.
- Apply well before departure. Most applications are approved quickly, but some take considerably longer, and there is no way to rush one at the gate.
- Approval is not a guarantee of entry. The immigration officer at the border makes the final decision. This is standard everywhere, but it surprises people who assume an approval is a boarding pass.
- Once approved, it covers multiple entries during its validity, so the cost is spread across trips.
- With a valid K-ETA, they skip the arrival card.
The most common failure here is not rejection. It is leaving the application until two days before the flight.
Group 3: A Visa Is Required — What You Actually Have to Do
This is where being the host stops being advisory and becomes administrative.
The structural fact to internalise: your friend applies in their own country. Not at an immigration office in Korea. The application goes to the Korean embassy or consulate with jurisdiction over where they live. You prepare documents in Korea and send them abroad.
That reverses what most people expect, and it drives the whole timeline.
The relevant category is the short-term visit visa (C-3), which covers tourism, family visits, visiting friends, short business trips, medical visits, and attending events or conferences. Within it there are sub-categories, and a family visit is handled differently from general tourism.
What You Send From Korea
The specific list depends on the consulate, and consulate requirements differ enough that you must read the page for your friend’s consulate rather than a general guide. But the pattern is consistent, and one item is confirmed and non-negotiable:
Your residence card, both sides. For a family-visit application where the person in Korea is a long-term foreign resident, consulates require a copy of your valid residence card or overseas-Korean resident card — front and back. This is stated explicitly in official consulate guidance. If you have not yet received your card, see our guide to getting your residence card, because the visa timeline depends on yours existing first.
Beyond that, the pattern typically includes:
- A letter of invitation from you. There is no single mandatory format; some consulates publish a template, others accept your own. What matters is that it states the specific dates, the reason for the visit, the relationship, and where your guest will stay.
- Proof of your relationship, for family applications.
- Proof of accommodation — for a friend staying with you, confirmation of where they will be staying.
- A return flight booking.
- Evidence of how the trip is funded, which may be theirs or yours depending on the case.
Some invitation scenarios also involve additional guarantee documents. If a consulate asks for one, read what you are signing before you sign it — a guarantee is a commitment, not a formality, and it is worth asking the consulate directly what it obligates you to.
Things we deliberately are not listing: visa fees and consulate-specific document checklists. Both vary by country and are revised without notice. Sending your friend to their own consulate’s page is more useful than any table we could publish.
Why Applications Get Refused
The common thread in refusals is not paperwork quality. It is that the application does not clearly establish the visit is temporary. Vague dates, no return booking, an invitation letter that reads like a form, no clear picture of who is paying — these read as risk. Specificity is the fix. Real dates, a real itinerary, a real explanation of the relationship.
A Realistic Timeline
Work backwards from the flight.
Eight weeks out. Establish which group your friend is in. If Group 3, find their consulate’s page and read the actual requirements.
Six weeks out. If a visa is needed, send your documents. Processing can take three to four weeks and longer in peak season or if the consulate requests additions.
Four weeks out. Flights and accommodation confirmed. If your friend is Group 2, K-ETA applied for now rather than later.
Two weeks out. Talk through what they should set up before flying — payment, phone, transit. Details below.
Three days out. If they are submitting the e-Arrival Card, this is the window. Not earlier.
Arrival day. See below.
For Groups 1 and 2 you can compress all of this considerably. For Group 3 the six-week mark is not padding.
Arrival Day
Your guest lands, and the friction is all in the first two hours.
Do not plan to meet them at the gate. Arrivals means the arrivals hall, after immigration and baggage. Immigration queues at Incheon vary from fifteen minutes to well over an hour depending on the hour and the flight bank.
Decide in advance how they get to the city. If you are collecting them, fine. If not, brief them properly, because a jet-lagged person improvising airport transport at 11pm makes expensive choices. Our guide on getting from Incheon Airport to Seoul covers the actual options and what each costs.
Have their phone working before they leave the airport. A guest without data cannot find you, cannot call you, and cannot use a map. Handle this with a SIM or eSIM sorted out in advance — see our guide to SIM cards and eSIMs. An eSIM they activate before boarding is the lowest-friction version.
Get them a transit card at the airport, or give them one. If you have a spare T-money card in a drawer, that is the simplest gift you will ever give. Otherwise they buy one at a convenience store. Our T-money guide covers it, and Korea’s transit passes is worth reading if they will be riding constantly.
Small amount of Korean cash. Korea is overwhelmingly card-based, but a guest with zero won has no fallback if a card is rejected. Convenience-store levels of cash, not travel-fund levels. If they are bringing foreign notes, a WOWPASS machine converts them at a better rate than an airport exchange counter — though the machines at Incheon take Korean won only, which is exactly the kind of detail worth knowing before they land.
What Your Guest Can Do That You Cannot
This is the part hosts get wrong, and it costs the guest money. Several Korean products are restricted to short-term visitors. You lost access to them the moment you became a resident — but your friend has it, and only while they are here.
Tax refunds on shopping. Short-term visitors can reclaim value-added tax on qualifying purchases. As a resident, you cannot. Tell your friend this before they shop, because the refund depends on how the purchase is handled at the point of sale. Discovering it at the airport is discovering it too late.
The KORAIL PASS. Korail sells an unlimited-travel rail pass, and your visiting friend is exactly the intended customer. Worth pricing against individual tickets if they are doing several long-distance trips.
Two things to know, because most guides get them wrong. First, the only exclusion in Korail’s current terms is Korean nationality — the widely repeated claim that foreign residents with six months or more in Korea are barred does not appear in the terms as published. If you are a resident wondering whether you could use one too, do not take a blog’s word for it in either direction; ask Korail before paying. Second, the pass is not a substitute for a ticket. It excludes SRT, metropolitan railway lines and special or temporary tourist trains — though Korail’s regular scheduled tourist trains are covered, which is the distinction most guides flatten in one direction or the other. A first-class seat costs extra on top of the pass, and a sold-out train means standing. Two details worth flagging to your friend: refunds are only possible before the start date, not after, and pass holders cannot claim the delay compensation that ordinary ticket holders can. Prices and conditions change, so check Korail’s own page.
Visitor-only prepaid cards. WOWPASS is issued to foreign nationals only, on a passport, from a machine — currency exchange, card payment and transit on one piece of plastic. Genuinely useful for a guest arriving with foreign cash, with two catches you should warn them about: it cannot pay online at all, and the shopping balance and the transit balance are separate. Our WOWPASS guide covers the fees, the limits and the airport machines that are easy to miss.
The reverse also applies. Things you can do that they cannot: anything requiring Korean identity verification. Delivery apps, most Korean online shopping, app-based taxi payment, ticket sites that demand a Korean phone verification. Your friend will hit these walls constantly. Practically, this means you become their online-payment layer for the week — you book, they pay you back. Set that expectation early rather than watching them fail at a checkout screen four times.
Our roundup of useful apps for foreigners in Korea covers which ones actually work without a Korean identity number.
Practical Things Nobody Warns Hosts About
Your accommodation may have rules. Company housing, university dormitories and some officetel buildings restrict overnight guests or require notification. Check your own contract before you promise anyone a bed. This is a lease question, not an immigration one.
Plan fewer things than you want to. Your friend has jet lag and you have a job. The standard host mistake is scheduling six days of activities and then spending them exhausted. Two anchored plans a day is plenty.
Feed them somewhere ordinary early on. The most memorable meals your guest has will not be the expensive ones. Traditional markets are the highest-return, lowest-cost outing available — see Seoul’s traditional markets. Bring cash for these.
Save the emergency numbers to their phone, not just yours. If you get separated and their phone works but yours does not, that matters. Our emergency numbers guide has the list, including the interpretation lines.
Write down your address in Korean. Give it to them on paper and in a message. A taxi driver needs the Korean address, and a guest who cannot pronounce it and has no data is genuinely stuck.
FAQ
Does my friend need a visa to visit me in Korea? It depends entirely on their passport. Many nationalities enter visa-free; others need a short-term visit visa applied for at a Korean embassy or consulate in their own country. Check the official visa portal for their specific nationality.
Is K-ETA required in 2026? Not for nationals of the countries under the Ministry of Justice’s temporary exemption, which runs through 31 December 2026 and includes the United States. Nationals of visa-free countries not covered by that measure do need it. Whether it returns as mandatory after 2026 has not been announced.
I read that US citizens need K-ETA from January 2026. Is that true? No. Korean embassy notices confirm the exemption was extended through the end of 2026 with the US included. That claim has circulated widely and is incorrect.
Does my friend need to submit the e-Arrival Card? If they hold a valid K-ETA, no — K-ETA holders are exempt from the arrival declaration. If they are entering visa-free without a K-ETA, yes. It is free, submitted online, and can be filed within three days before arrival.
So should my friend get a K-ETA even though they’re exempt? It is a genuine trade-off. Exempt travellers may apply voluntarily and pay the fee, which then exempts them from the arrival card for the authorisation’s validity — generally around three years, multiple entries. Worth it for someone who will return; not worth it for a single trip.
Are there age exemptions for K-ETA? Yes. Among nationals of visa-free countries, travellers aged 17 or under and 65 or over are outside the K-ETA requirement. They would still submit the arrival card.
Can I apply for my friend’s visa here in Korea? No. Short-term visit visa applications are made at the Korean embassy or consulate with jurisdiction over where your friend lives. You prepare supporting documents in Korea and send them.
What do I have to provide as the host? For a family visit where you are a long-term foreign resident, a copy of both sides of your residence card is required. Beyond that, expect an invitation letter with specific dates and purpose, proof of relationship for family cases, accommodation details and a return booking. Requirements vary by consulate — read your friend’s consulate’s page.
How long does a visa take? Allow three to four weeks for processing, and longer in peak periods or if the consulate asks for additional documents. Starting six weeks before the flight is realistic; four is tight.
How long can my friend stay? Visa-free stay periods vary by nationality under the relevant agreement, and a short-term visit visa is capped at 90 days. Both are specific to the passport, so check rather than assume.
Can my friend stay at my apartment? Immigration does not require you to report an ordinary guest. Your lease might, though — company housing and dormitories often restrict overnight visitors. Check your own contract.
Can my friend get a tax refund on shopping? Short-term visitors can reclaim VAT on qualifying purchases. Tell them before they shop, since it depends on how the sale is processed. You, as a resident, cannot.
Why can’t my friend order delivery food? Korean online payment and delivery platforms generally require domestic identity verification, which a short-term visitor does not have. In practice you order and they reimburse you.
Should my friend bring cash or just cards? Mostly cards — Korea is a card country. But some cash is worth carrying for market stalls, street food and older shopping arcades.
