Vietnam Visa for Korean Citizens: The 45-Day Exemption and When to Get an E-Visa

Work-from-Da Lat: What the Highland Nomad Scene Actually Looks Like

Da Lat has quietly become Vietnam's most liveable remote-work base — cool air, cheap rent, and more cafes than you can reasonably test in a month.

Korean passport holders have one of the more straightforward arrangements for entering Vietnam (베트남 / 越南 / ベトナム). No embassy queues, no sticker visa, no paperwork — just show up at the border and you get 45 days. That covers most holidays comfortably. But if you are planning a longer trip, working remotely, or hopping between Vietnam and a neighboring country, the visa-free window has limits worth understanding before you book.

The 45-Day Visa-Free Entry

South Korean nationals can enter Vietnam without a visa and stay for up to 45 days. This applies to arrivals by air, land, and sea. The exemption covers tourist visits and does not require any pre-registration or prior approval.

A few conditions apply:

• Your passport must be valid for at least six months beyond your intended stay.
• The 45-day clock starts on your date of entry, not departure from Korea.
• There is no guaranteed automatic renewal. If you leave Vietnam and re-enter, you get a new 45-day window — but immigration officers have discretion, and frequent short turnarounds on visa runs can attract scrutiny.

For a two- to three-week trip — say, Hanoi in the north down to Hoi An and Saigon — the visa-free entry is all you need. Most travelers visiting Ha Long Bay, spending a few days in Hue, or eating their way through Da Nang will never bump against the limit.

When the 45 Days Is Not Enough

The visa-free window works until it does not. Here are the situations where you should look at alternatives.

You want to stay longer than 45 days. Remote workers, slow travelers, and people spending extended time in places like Da Lat (달랏 / 大叻 / ダラット) or Phu Quoc often want 60, 90, or even more days. The visa-free exemption cannot be extended once you are inside Vietnam — there is no in-country mechanism to add days onto a visa-exempt stay.

You need multiple entries with certainty. If your itinerary takes you from Vietnam to Laos or Cambodia and back, technically you can re-enter on the exemption. But re-entry is at the discretion of the border officer. An e-visa removes that uncertainty by guaranteeing your entry right.

You are traveling on business. The visa-free exemption is for tourism. Business visits technically require a business visa, though in practice short trips often pass without issue. If your employer requires documentation or you want a clean paper trail, an e-visa with a business purpose is the correct route.

The Vietnam E-Visa: How It Works

Vietnam's e-visa is available to Korean citizens and is issued through the official Immigration Department portal (immigration.gov.vn). Do not use third-party agents — they charge a premium for a process you can complete yourself in about 20 minutes.

What you get: A single or multiple-entry e-visa valid for up to 90 days. As of 2023, Vietnam extended the maximum e-visa duration from 30 to 90 days, which makes it genuinely useful for longer stays.

What it costs: The fee is around 25 USD for both single and multiple-entry. Pay by card during the online application.

Processing time: Typically three business days. Apply before you travel — do not leave it to the night before your flight.

What you need to apply:

• A passport valid for at least six months beyond your intended stay
• A passport-style photo (digital, recent)
• A scan of your passport bio page
• Your intended entry and exit dates
• Your entry checkpoint (select the airport or border crossing you plan to use)

Once approved, you receive a PDF e-visa document by email. Print it or keep a clear digital copy. Border officers will scan the QR code.

Single vs. Multiple Entry

If you are only entering Vietnam once and leaving at the end, single entry is fine. If you plan to cross into Cambodia to see Angkor Wat and return to Saigon, or cross overland into Laos from the northwest, get multiple entry. The price difference is minimal and the peace of mind is worth it.

Extending or Changing Your Visa Inside Vietnam

If you entered on the visa-free exemption and want to stay longer, your options are limited. You cannot convert a visa-exempt stay into an e-visa while inside the country. Your main options are:

1. Do a border run — exit to a neighboring country and re-enter (not guaranteed, as noted above).
2. Apply for a longer-stay visa through a Vietnamese immigration office, which requires more documentation and is slower.

The cleaner move is to decide before you travel. If there is any chance you will want more than 45 days, get the 90-day e-visa before you leave Korea.

A Note on Arrival Airports and Land Borders

The e-visa is accepted at all major international airports — Hanoi (Noi Bai), Saigon (Tan Son Nhat), Da Nang, Phu Quoc, and others — as well as most major land border crossings. When you fill out the application, select your specific entry point. Some smaller land crossings are not on the approved list, so check the current approved checkpoints on the official portal before applying.

Practical Notes

For most Korean travelers, the 45-day exemption is enough — just bring a valid passport and you are in. If you are staying beyond 45 days or need guaranteed multiple entries, the e-visa is the right call: apply at immigration.gov.vn, budget three business days, and pay around 25 USD. Skip the third-party agents.
