🇺🇸 Do citizens of South Korea need a visa for the United States?
eTA (electronic authorization)
Citizens of South Korea need an electronic travel authorization (eTA) for the United States. It is not a full visa but an online registration to complete before departure, best done well ahead of time.
The United States runs one of the strictest entry systems in the world: most travelers need a B-2 visitor visa, while Visa Waiver countries use ESTA. Requirements differ sharply by passport, so check your exact rule below before booking.

What this means in practice
An eTA is not a visa: it is a short online registration, passport details and a few questions about your trip, plus a small fee paid by card. Approval is usually returned within minutes, and the authorization is linked electronically to your passport, so there is nothing to stick inside it. Airlines typically check for a valid eTA at check-in, so it needs to be in place before you fly, not on arrival.
⚠️ Mandatory before you fly
A visa is not the only thing this destination checks. The following must be completed in advance, even when no visa is required.
Electronic System for Travel Authorization (ESTA)
When: Before boarding; CBP advises applying as soon as you start planning the trip
This is authorisation under the Visa Waiver Program, not a substitute for a visa: if you need a visa, ESTA is not for you. Every traveller needs their own approval, children of any age included. Without it you may be denied boarding. A biometric e-passport is required. There is a fee, charged on the official site: CBP still publishes outdated amounts on its own older pages, so read the current figure at esta.cbp.dhs.gov rather than anywhere else.

Before you go
- Check your passport's expiry date: many countries require it to stay valid for at least three to six months after your return date, not just past your travel date.
- Carry proof of a return or onward ticket; border officers sometimes ask for it even for visa-free entry.
- Save offline copies of anything important (confirmations, hotel booking, visa approval): airport wifi is not guaranteed, and immigration desks often have no signal.
- You do not need the eTA before booking flights, but get it early: it is tied to your passport number, so a new passport means applying again.
Visa rules are set unilaterally by each country, often on a reciprocal basis: when one side eases entry, the other frequently matches it, and tightening can go the same way in reverse. Rules shift because of new agreements, political developments, seasonal pilot programs or plain administrative decisions, sometimes with little public notice in advance. Aviozo checks this visa dataset regularly, but the exact rule on your travel date is ultimately confirmed only by the official source or the destination's consulate.

Frequently asked questions
Is there anything else to complete before flying to United States?
Yes. Beyond the visa rule there is a mandatory pre-arrival formality: Electronic System for Travel Authorization (ESTA) (Before boarding; CBP advises applying as soon as you start planning the trip). Without it you can be turned away at the border even when no visa is required.
Do citizens of South Korea need a visa for the United States?
No full visa is needed in advance. The current rule is "eTA (electronic authorization)".
How long can citizens of South Korea stay in the United States without a visa?
Visa-free stays are allowed for up to 90 days. Longer stays or other trip purposes may require a separate visa.
How current is this data?
This pair's rule was taken from the official source on 10 August 2026: that is the date the whole destination was read, not a separate human reading of this one pair. Separately, a robot checks that the source link is still alive: it last responded on 18 August 2026. Visa rules can change with little notice, so double-check the official site a few days before you fly.
Does this rule apply to diplomatic or official passports?
No, this data is based on an ordinary tourist passport. Diplomatic, official and other special passports often follow a different entry rule, so check that separately.
Can I extend my stay once I am there?
Our dataset does not track extension rules; they are set by each country and depend on the specific authorization you hold. Check with the destination's consulate or immigration authority before your permitted stay runs out.
Do I need travel insurance?
We do not track insurance requirements; some e-visas and eTAs list a policy as a condition of approval, so check the official application. Either way, insurance is a sensible precaution for any trip abroad, regardless of the visa rule.
Does this rule cover work or study?
The data reflects the general tourist entry rule. Work, study or long stays usually require a separate visa, so check the official government site.
