Question	If yes	If no or unsure
Do you already hold a valid Korean visa or residence card for this trip?	Follow the conditions attached to that document and confirm them with the issuing authority. A valid visa takes priority over K-ETA.	Continue to the Visa Portal check.
Does the official Visa Portal show that your passport and trip can use visa-free entry?	Check K-ETA next.	Follow the visa instructions for your purpose and contact the responsible Korean embassy or consulate.
Does the official K-ETA service say you need K-ETA now?	Apply only through k-eta.go.kr and allow extra time beyond the normal assessment estimate.	Save evidence of the current exemption or result and continue to the arrival-card check.
Will you enter visa-free using a valid K-ETA?	The official navigator may show that no arrival declaration is required.	Select every document valid at entry in the Navigator. If you will enter on a visa, expect to submit the arrival declaration even if you also hold K-ETA, unless another exception applies.
Did you stay in or transit through a strict quarantine inspection required area?	Submit Q-CODE or a Health Declaration Form under current KDCA guidance, whether or not you have symptoms.	Continue to the next quarantine check.
Did you stay in or transit through another quarantine inspection required area and have relevant symptoms?	Submit Q-CODE or a Health Declaration Form under current KDCA guidance.	Do not assume Q-CODE is universal; recheck the current designated areas shortly before departure.

What to have ready

• The exact passport you will use to board and enter Korea
• Passport nationality and passport type
• Age on the planned arrival date
• Purpose of travel
• Intended arrival and departure dates
• Planned length of stay
• Accommodation address and contact details in Korea
• A list of countries or regions where you recently stayed or transited
• Whether checked baggage is transferred through or must be reclaimed during transit
• Access to your airline’s current document-check page

Step 1 — Define your exact case

Before searching, write down six facts:

1. Passport nationality and type
2. Age on the planned arrival date
3. Reason for travel
4. Intended length of stay
5. Planned arrival date
6. Any valid Korean visa or residence card you will use

Changing any one of these can change the result. A rule that applies to a short tourist visit may not apply to work, study, paid activity, long-term stay, transit, or a different passport type.

Avoid the common “six-month passport rule” shortcut. Do not assume that one validity period applies to every passport and itinerary. Confirm the rule shown for your case and also check the airline’s boarding requirements.

Step 2 — Check whether you need a visa

Start with the Korea Visa Portal Visa Navigator. Use it for your nationality or region, purpose, and length of stay.

If it shows that a visa is required:

• Follow the instructions for the correct visa category.
• Check the Korean embassy or consulate responsible for the place where you live or apply.
• Confirm required documents, appointment rules, fees, and processing time directly with that office.
• Do not buy a non-refundable flight based only on an unofficial checklist.

If it shows that you may enter without a visa, continue to the K-ETA check. Visa-free eligibility and K-ETA are related but separate questions.

Step 3 — Check K-ETA separately

K-ETA is an electronic travel authorization for eligible visa-free travelers. It is not a visa, and an approval does not guarantee entry. The final entry decision is made by a Korea Immigration Service officer.

As checked on August 10, 2026, the Ministry of Justice notice says the temporary K-ETA exemption for the countries already covered by the measure was extended through December 31, 2026 (KST). The official site determines whether the measure applies to your passport; do not copy a static country list from an old article.

Use only the official K-ETA website. The official guide currently lists:

• Application fee: KRW 10,000, plus an online payment fee
• Normal assessment estimate: generally within 72 hours, but it can take longer
• No expedited assessment service
• A new application may be required after passport reissue or certain information changes

If your passport is temporarily exempt, you may still be able to apply voluntarily. For a visa-free traveler who actually enters using a valid K-ETA, one practical benefit is exemption from the arrival declaration. That benefit does not apply merely because a visa traveler also holds K-ETA. Compare the relevant benefit with the fee and the risk of unnecessary third-party charges.

Do not confuse these three facts

• Visa-free does not automatically mean K-ETA-free.
• K-ETA-exempt does not automatically mean arrival-card-exempt.
• A K-ETA validity period is not the same as your permitted length of stay.

Transit requires a separate answer

Do not publish or rely on the blanket claim that transit passengers never need entry authorization. An airside transfer can be treated differently from an itinerary that requires you to pass Korean immigration, reclaim bags, change airports, or stay overnight. Ask the airline whether your baggage is checked through and whether the itinerary requires entering Korea, then run the visa and K-ETA checks for that exact route.

Step 4 — Check the e-Arrival Card

The official Korea e-Arrival Card is a free electronic arrival declaration. The official service accepts a submission starting three days before arrival in Korea, based on Korean Standard Time. The official guide states that a submitted declaration expires after 72 hours or once immigration processing is completed.

Use the official navigator and select every visa, K-ETA, and residence card that will be valid at entry. The Navigator states that a valid visa holder is normally examined on the visa and must submit the arrival declaration even when they also hold K-ETA. For a visa-free traveler entering with K-ETA, a valid K-ETA is among the exemption categories. Registered residents and several special categories may also be exempt.

If you are temporarily exempt from applying for K-ETA but do not hold a valid K-ETA, do not assume that the same exemption removes your arrival-card obligation. Check the e-Arrival Card Navigator.

Prepare:

• A valid passport
• An email address and access to that inbox for the verification code required at submission
• Arrival and departure details
• Address and contact information for your stay

The official service is free and uses the domain e-arrivalcard.go.kr. A site that requests payment for the Korean e-Arrival Card is not the official service.

Step 5 — Check whether Q-CODE applies to your route

Q-CODE is a Korean health and quarantine information system. It is not a blanket form that every traveler should automatically complete.

Under KDCA’s Q3 2026 guide, effective July 1, 2026, the two area categories have different route rules:

• If you stayed in or transited through a strict quarantine inspection required area, submit Q-CODE or a Health Declaration Form whether or not you have symptoms.
• If you stayed in or transited through another quarantine inspection required area, submit Q-CODE or a Health Declaration Form when you have relevant symptoms such as fever or cough.

Use the KDCA Q-CODE guidance, the current quarterly area notice, and the official Q-CODE service. Recheck shortly before departure because designated regions and procedures can change each quarter.

The current KDCA guide says Q-CODE can be registered starting seven days before arrival. The reporting rule still depends on the latest area designation, route, and—outside strict areas—health status.

Step 6 — Treat customs as a separate check

Visa permission, K-ETA, an arrival declaration, health reporting, and customs are different systems. Completing one does not replace the others.

Review the Korea Customs Service traveler information for goods, food, medicines, cash or payment instruments, and other items you plan to carry. If an item may be restricted or declarable, use the current official traveler declaration guidance or ask Korea Customs before travel.

This guide intentionally does not reproduce a fixed allowance or currency threshold because those details require their own dated customs check.

A safer preparation timeline

Before booking

• Confirm visa or visa-free eligibility for the exact passport and trip purpose.
• Check whether the trip involves work, study, paid activity, long stay, transit, or another special category.
• Check passport validity requirements with the official authority and airline.

At least several weeks before departure

• Complete any required visa process.
• If K-ETA is required, apply through the official site and leave margin beyond the normal assessment estimate.
• Save the result and check whether travel information must be updated later.

Seven days before departure

• Recheck Visa Portal, K-ETA notices, and your airline’s document requirements.
• Check whether KDCA route-based health reporting applies.
• Review any medicines, food, cash, or goods that may need a customs check.

Starting three days before arrival

• If required, submit the free e-Arrival Card on the official site.
• Recheck flight, terminal, accommodation address, and contact details.

Before leaving for the airport

• Confirm that the passport number on every approval matches the passport in your hand.
• Keep visa, K-ETA, arrival-declaration confirmation, accommodation, and onward-travel evidence available offline where relevant.
• Check for a last-minute airline or government notice.

Symptom	Likely cause	What to do
An airline says a document is missing even though a blog said it was not needed	The article used an old country list or a different passport/purpose	Open the official Visa Portal and K-ETA result for the exact passport; ask the airline to identify the document it requires.
You are K-ETA-exempt but still see an arrival-card requirement	K-ETA exemption and arrival-card exemption are different	Use the official e-Arrival Card Navigator and submit the free declaration if instructed.
A site asks for a high “e-Arrival Card fee”	It is not the free official government service	Stop and use only e-arrivalcard.go.kr. Do not enter payment details.
A K-ETA result is tied to an old passport	Passport information changed after approval	Follow the official K-ETA reapplication guidance before boarding.
The e-Arrival system does not accept your date yet	The submission window has not opened	Return when your arrival is within the official three-day window.
Q-CODE advice online conflicts	The designated-region list or health procedure changed	Use the latest KDCA guidance for places stayed or transited and your current symptoms.

Special cases that need a direct official answer

Contact the responsible Korean authority, embassy, or consulate instead of relying only on this guide if any of these apply:

• Work, study, performance, journalism, paid activity, or long-term stay
• Dual nationality or use of a non-standard passport or travel document
• A current or previous Korean residence status
• Transit without formally entering Korea
• Group-tour or special visa arrangements
• Previous visa refusal, overstay, deportation, or criminal-record issue
• A minor traveling alone or with only one parent or guardian
• Medicines, controlled items, large amounts of cash, or restricted food or animal products

If the online answer is still unclear

Use this fallback order:

1. Save screenshots or PDFs of the result shown by the official Visa Portal, K-ETA service, and e-Arrival Card Navigator.
2. Ask the Korean embassy or consulate responsible for your place of residence, giving your passport nationality, purpose, intended stay, and travel dates.
3. Use the Korea Immigration Contact Center information listed on the official Korea Immigration Service website.
4. Confirm the airline’s boarding-document requirements for your exact route.
5. Do not pay an unofficial agent merely to interpret a generic online country list.

Frequently asked questions

Is K-ETA the same as a visa?

No. The official K-ETA guide states that K-ETA is not a visa and does not guarantee entry.

If I am K-ETA-exempt in 2026, do I still need an e-Arrival Card?

Possibly. Temporary K-ETA exemption does not itself prove that you are exempt from the arrival declaration. Use the official e-Arrival Card Navigator for the documents you will hold at entry.

Can I submit the e-Arrival Card weeks in advance?

No. The official service opens the submission window starting three days before arrival in Korea, based on Korean Standard Time.

Is the e-Arrival Card paid?

No. The official Korean government service is free. Avoid lookalike sites that request payment.

Does every traveler need Q-CODE?

Not automatically. Travelers who stayed in or transited through a strict quarantine inspection required area must report under current KDCA guidance even without symptoms. For another quarantine inspection required area, the reporting rule applies when the traveler has relevant symptoms. Recheck the current quarterly designation before departure.

Does approval of a visa or K-ETA guarantee entry?

No. Final entry permission is determined by Korean immigration authorities at the port of entry.
