Things to Know Before Coming to South Korea

Mục Lục

When planning your trip to the Land of Kimchi, learning about the essential things to know before coming to South Korea is the first step toward a smooth, fulfilling, and memorable journey. Beyond its fame for K-pop, movies, and cuisine, South Korea is also one of Asia’s top destinations for studying abroad, working, and cultural tourism.

Overview of Preparation Before Coming to South Korea

According to the Korea Tourism Organization (KTO), the country welcomes over 11 million international visitors each year, with Vietnamese arrivals growing by more than 10% annually.

However, to fully enjoy your experience, you should carefully prepare everything from immigration procedures, luggage, cultural knowledge, and transportation to local cuisine. Understanding the basics before you go not only helps you avoid procedural or behavioral issues but also allows you to adapt quickly to the new environment.

Immigration Procedures and Essential Luggage

The first and most important step in your South Korea journey is preparing for immigration. Knowing the rules in advance will help you avoid airport issues and save both time and money once you arrive.

Common Types of Korean Visas for Vietnamese Citizens

According to the Embassy of South Korea in Vietnam, Vietnamese travelers can enter the country under the following Korea visa types:

C-3 Visa (Short-term Visit): Suitable for tourism, family visits, or short business trips of 15–90 days.
H-1 Visa (Working Holiday): For Vietnamese citizens aged 18–30, allowing a 12-month stay for combined study and work.
D-2 Visa (Student Visa): For students pursuing undergraduate, master’s, or doctoral programs in South Korea.

Since 2021, the Korean government has introduced the K-ETA (Korea Electronic Travel Authorization) system, an electronic entry permit for citizens of over 100 countries, including Vietnam.

Note: K-ETA is not a visa, and approval does not guarantee entry. Final decisions rest with immigration officers.

If you want to save time and avoid mistakes during your journey, don’t hesitate to contact iVISA. The company offers complete visa and K-ETA services – checking, processing, and delivering results efficiently and securely.

Required Documents and Luggage for Your Trip to South Korea

To ensure smooth immigration, prepare the following documents:

Passport valid for at least six months beyond your departure date.
Round-trip flight ticket.
Hotel booking confirmation or invitation letter (for business trips).
International travel insurance.
Cash and international payment cards.

Packing tips:

Clothing: Choose outfits suitable for the weather. Winter Korea temperatures can drop to –10°C, while summer can reach 35°C. Pack season-appropriate clothes.
Power adapter: South Korea uses 220V electricity and plug types C, E, and F. Bring compatible adapters.
Personal medicine and first aid kit.
Do not bring: Fresh food, meat, or dairy products without quarantine certificates, as South Korea strictly regulates these items (Source: Korea Customs Service).

If this is your first trip to South Korea, handling all procedures alone may be confusing. Don’t worry – iVISA can help you complete every step from A to Z, ensuring a hassle-free journey.

Culture and Etiquette When Traveling in South Korea

When planning your trip, understanding Korean culture and etiquette is essential. South Korea values politeness, order, and appropriate behavior in all situations. Knowing these basic rules not only helps you avoid awkward moments but also enhances your overall Korea travel experience.

Culture and Customs

Koreans highly respect hierarchy and courtesy. When greeting elders or meeting someone for the first time, a slight bow is a polite gesture. Avoid overly intimate gestures like hugging, patting shoulders, or back-slapping, which may be seen as impolite.

If you plan to study or live in Korea long-term, mastering these etiquette basics will help you integrate quickly and leave a good impression.

Communication and Public Behavior

In public places such as subways, buses, or shopping Korea areas, Koreans maintain order and speak softly.

On public transport: Avoid loud phone calls, eating, or littering.
In queues: Always wait in line and avoid cutting in.

If you travel during South Korea’s peak tourism season (around November) when golden leaves blanket the streets, be especially mindful of maintaining order and respecting shared spaces, as crowds are common during this time.

Dining Etiquette

Korean cuisine is deeply tied to social etiquette:

Do not stick chopsticks upright in a rice bowl – it symbolizes funerals.
When pouring alcohol for others, use both hands or one hand while supporting your elbow with the other.
Wait for elders or the host to start eating first.
Remove your shoes when entering homes or traditional restaurants if others do so.

Transportation and Getting Around

Transportation is one of the most important things to know before coming to South Korea. With a highly modern system, traveling around the country is extremely convenient.

A Modern Transportation System

South Korea has one of Asia’s best transportation networks. In major cities like Seoul, Busan, and Incheon, you can easily choose among subways, buses, taxis, or the high-speed KTX train.

Subways: The most popular option – fast, cheap, and punctual.
City and intercity buses: Ideal for reaching suburban or local areas.
KTX high-speed trains: Great for saving time on long-distance routes.
Taxis: Flexible and convenient for short trips or heavy luggage.

T-Money Card: A Must-Have Travel Item

One essential thing to know before visiting South Korea is the T-Money card, a prepaid transportation card used for subways, buses, and even convenience stores.

You can buy a T-Money card at GS25, CU, or 7-Eleven stores and top up at subway kiosks or cashier counters. Simply tap the card when boarding and exiting transport, and the fare will be automatically deducted.

Taxis: Convenient but Costly

South Korean taxis are clean, safe, and strictly regulated, with several service types:

Standard Taxi: Affordable and widely available.
Deluxe Taxi (모범택시): Spacious, professional drivers in suits, but higher fares.
International Taxi: English-speaking drivers – perfect for tourists and newcomers.

However, taxis can be expensive, especially late at night or far from downtown. Combine subways and buses for more cost-effective travel.

Useful Travel Apps

Technology makes transportation in Korea even easier:

Naver Map and KakaoMap: More accurate than Google Maps for local routes.
KakaoTaxi: English-friendly app for quick taxi booking with international card payments.
T-Money App: Lets you track balance, transaction history, and top up online.

Mastering these apps saves time – especially during peak travel seasons like November, when public transport is often crowded.

With a bit of preparation, you can fully enjoy your trip without health worries.
