Moving to South Korea from Vietnam

Visa Pathways for Vietnamese Nationals

Vietnamese nationals need a visa for all entries to South Korea. The Korea Immigration Service (Hi Korea) administers visa categories under the Immigration Control Act ^[1].

E-9 (Non-Professional Employment).

This is the most common visa category for Vietnamese workers in South Korea. The Employment Permit System (EPS), governed by a bilateral memorandum of understanding between South Korea and Vietnam, brings workers into manufacturing, agriculture, fisheries, and construction ^[2]. Vietnamese nationals consistently rank among the largest E-9 holder groups. The Vietnamese Ministry of Labour, Invalids and Social Affairs (MOLISA) coordinates outbound EPS workers through the Centre for Overseas Labour (COLAB) ^[3]. Applicants must pass the Korean language test (EPS-TOPIK) and a skills evaluation before being placed in the applicant pool.

E-7 (Specially Designated Activities).

The skilled professional visa, available to Vietnamese nationals with employer sponsorship for roles matching designated occupation codes ^[1]. This path requires a job offer from a Korean employer and typically a university degree or equivalent professional experience. Processing takes several weeks through the employer's local immigration office.

D-2 and D-4 (Student Visas).

D-2 covers degree programs at accredited Korean universities, while D-4 covers Korean language training programs ^[1]. Vietnamese students are one of the largest international student groups in South Korea. After completing a degree, D-2 holders can transition to a D-10 (Job Seeking) visa and then to E-7 employment.

F-2 (Resident Visa).

A points-based long-term residence visa for qualifying professionals, scored on income, education, Korean language proficiency (TOPIK level), age, and tax compliance ^[1]. F-2 holders are not tied to a single employer.

F-5 (Permanent Residence).

Available after extended continuous residence on an eligible visa, meeting income, language, and civics requirements through the Korea Immigration and Integration Program (KIIP) ^[2].

Marriage migration (F-6).

Vietnamese nationals married to Korean citizens can apply for the F-6 visa ^[2]. Vietnamese-Korean marriages represent a significant share of international marriages in South Korea, and the Korean government provides integration support through multicultural family support centers.

Application process.

Vietnamese applicants apply at the Korean Embassy in Hanoi or Consulate in Ho Chi Minh City. Required documents include a valid Vietnamese passport, purpose-specific documentation (employment contract, university admission, marriage certificate), criminal background check, and health certificate. Some visa categories require documents authenticated by Vietnamese authorities before submission.

Tax Obligations

South Korea taxes residents on worldwide income through the National Tax Service (NTS) ^[1]. You become a Korean tax resident if you maintain a domicile in Korea or reside for 183 days or more in a tax year ^[1].

The Korea-Vietnam Tax Treaty.

The Agreement for the Avoidance of Double Taxation between South Korea and Vietnam has been in force since 1994 ^[2]. The treaty assigns taxing rights and provides foreign tax credit mechanisms to prevent double taxation on the same income ^[2].

Income tax rates.

South Korea applies progressive income tax rates ranging from low single-digit percentages on the first bracket to higher rates on upper brackets ^[1]. Local income tax adds roughly 10% of the national income tax amount ^[1]. For E-9 workers, employers handle withholding through monthly payroll.

Flat-rate election for foreign workers.

Foreign workers in South Korea, including Vietnamese nationals, can elect a flat income tax rate on their Korean-source employment income instead of the standard progressive rates for a qualifying period ^[1]. This election can simplify tax planning, but whether it saves money depends on your income level. The flat rate and qualifying period are set by the NTS.

Year-end settlement.

Employees go through a year-end tax settlement (yeonmal jeongsan) in January/February, where the employer adjusts withholding for deductions and credits ^[1]. If you have income beyond employment (freelance work, rental income), you must file a comprehensive income tax return by May.

Vietnam tax obligations.

Vietnam taxes residents on worldwide income. When you leave Vietnam, you should settle your final tax obligations for the departure year. If you maintain Vietnamese income sources (rental property, business interests), you continue filing in Vietnam. The tax treaty prevents double taxation ^[2], but keeping records of taxes paid in both countries is necessary to claim credits.

Social security contributions.

Employees and employers both contribute to the National Pension Service (NPS), National Health Insurance (NHIS), Employment Insurance, and Industrial Accident Compensation Insurance ^[1]. Total employee-side deductions are roughly 9% of salary ^[1]. South Korea and Vietnam do not have a social security totalization agreement ^[2], so contributions in one country do not count toward benefits in the other.

Healthcare and Insurance

South Korea's National Health Insurance System (NHIS) covers all registered residents. Foreign nationals holding a visa valid for six months or more are enrolled after registering with their local immigration office ^[1].

NHIS coverage.

The system covers outpatient visits, hospitalization, surgery, prescription drugs, basic dental care, and preventive health screenings. Copays vary by service type, with clinic visits carrying lower copays than hospital outpatient departments. Hospitalization copays are a percentage of the total cost. Coverage is comprehensive by regional standards.

NHIS premiums.

For employed residents, premiums are calculated as a percentage of monthly salary, split between employer and employee. For self-employed or non-working residents, premiums are based on income, property, and other assets. E-9 workers have premiums handled through their employer.

Transition from Vietnam.

Vietnam's public health insurance does not provide coverage outside the country. Before departing, check whether any employer-provided insurance has an international component (uncommon). Private travel medical insurance covering South Korea is recommended for the period between arrival and NHIS enrollment.

Private supplementary insurance.

Many residents carry private insurance to cover NHIS copays, dental implants, vision, and services with limited public coverage. Major Korean insurers (Samsung Life, Hyundai Marine & Fire, DB Insurance) offer plans accessible to foreign residents.

Prescription drugs.

South Korea uses different brand names for many medications. Bring documentation listing your current prescriptions by generic (INN) name and dosage. Korean pharmacies require prescriptions for antibiotics and most medications beyond basic over-the-counter products. Some medications commonly available over the counter in Vietnam require prescriptions in South Korea.

Language barriers in healthcare.

Most Korean hospitals and clinics operate exclusively in Korean. Larger hospitals in Seoul and major cities have international clinics with interpreter services, but Vietnamese-language support is less common than English, Chinese, or Japanese. The government-run 1345 Foreign Resident Helpline provides phone interpretation services that can assist during medical visits.

Banking and Finances

Opening a Korean bank account.

You can open an account at major Korean banks (KB Kookmin, Shinhan, Woori, Hana, NH NongHyup) with your passport, Alien Registration Card (ARC), and proof of address. A Korean phone number is usually required. E-9 workers often have their employer assist with initial account setup since wages are deposited directly.

Remittances to Vietnam.

Sending money home is a priority for many Vietnamese workers in South Korea. Korean banks offer international wire transfers, but fees and exchange rate spreads reduce the amount received. Specialized remittance services like Wise, SentBe (a Korean fintech popular among migrant workers), and MoneyGram often offer better rates for KRW-to-VND transfers. Some Vietnamese community organizations provide guidance on the most cost-effective transfer methods.

Korean financial apps.

Daily transactions in South Korea increasingly run through mobile payment apps. KakaoPay, Naver Pay, and Samsung Pay are used at convenience stores, restaurants, and transit. You need a Korean bank account linked to these apps. Toss combines banking, payments, and budgeting in one app and is popular among younger residents.

Wages and labor protections.

South Korea's minimum wage applies equally to foreign workers. E-9 workers are covered by the Labor Standards Act, which mandates minimum wage, overtime pay, and severance pay ^[1]. If you experience wage theft or labor rights violations, the Ministry of Employment and Labor operates a complaint system, and the 1345 helpline provides Vietnamese-language interpretation.

Pension refund.

Vietnamese workers who contributed to the Korean National Pension Service (NPS) for fewer than 10 years can apply for a lump-sum refund of contributions upon permanent departure from South Korea. Apply at the NPS before leaving. The refund includes both employee and employer contributions plus interest.

Currency.

The KRW/VND exchange rate affects how much value your earnings represent when sent home. Track rates through your remittance provider and time larger transfers when rates are favorable. Exchange at banks or licensed money changers rather than informal channels to avoid scams.

Moving Logistics

Getting to South Korea.

Direct flights operate between Hanoi, Ho Chi Minh City, and Da Nang to Seoul (Incheon). Flight time is approximately five hours. Vietnamese carriers (VietJet, Vietnam Airlines, Bamboo Airways) and Korean carriers (Korean Air, Asiana, Jin Air, T'way Air) serve these routes. Budget options are available, especially on VietJet and T'way.

What to bring.

E-9 workers typically travel with personal luggage rather than shipping household goods. If you are moving for a professional role (E-7) or studies (D-2), shipping a small volume of personal items by sea freight from Vietnamese ports (Ho Chi Minh City, Hai Phong) to Busan or Incheon is cost-effective. Transit time is generally one to two weeks.

Customs.

Personal belongings used for six months or more are generally exempt from Korean customs duties under the household goods transfer provision. New items or commercial quantities are subject to duties and VAT. Food items, plant products, and animal products are inspected at entry.

Housing.

Korean rental options include jeonse (large lump-sum deposit, no monthly rent) and wolse (smaller deposit plus monthly rent). Most Vietnamese newcomers choose wolse since jeonse requires substantial capital. E-9 workers are typically housed in employer-provided dormitories, which are included as part of the employment arrangement. Quality of employer housing varies, and workers have the right to report substandard conditions to the Ministry of Employment and Labor.

Vietnamese communities.

Ansan (particularly Wongok-dong) has the largest concentration of Vietnamese residents in the Seoul metropolitan area, with Vietnamese restaurants, grocery stores, and community services. Other areas with notable Vietnamese populations include parts of Gimpo, Hwaseong, and certain industrial districts in Gyeonggi Province. These communities provide social support and familiar food during the adjustment period.

Phone and internet.

A Korean phone number is essential for banking, government services, and daily life. Prepaid SIM cards are available at convenience stores and airports, though some require your ARC. Postpaid plans from KT, SK Telecom, or LG U+ offer better rates for long-term residents. South Korea's internet speeds are among the fastest globally.

Pet import.

Dogs and cats entering South Korea from Vietnam need an ISO-compliant microchip, current rabies vaccination, and a health certificate from Vietnamese animal quarantine authorities. Rabies antibody titer testing may be required. Check the Korean Animal and Plant Quarantine Agency requirements before departure, as regulations for imports from Vietnam may differ from those for imports from rabies-free countries.

Cultural Adjustment

Language.

Korean is essential for daily life and employment in South Korea. Vietnamese and Korean share some structural similarities (both are agglutinative in certain grammatical features) but are not mutually intelligible. E-9 workers must pass the EPS-TOPIK Korean language test before arrival, but workplace Korean requires continued study. TOPIK proficiency (Level 3+) is needed for visa upgrades and many professional roles. Free Korean language classes are available through multicultural family support centers and local community centers.

Work culture.

Korean workplaces are hierarchical, with strong emphasis on seniority and group harmony. Honorific language (jondaenmal) is important in professional and social settings. Team dinners (hoesik) are common, and declining attendance can be viewed negatively, though this norm is gradually loosening among younger Koreans. Working hours can be long, especially in manufacturing settings.

Food.

Korean and Vietnamese cuisines share some ingredients (rice, noodles, fermented vegetables, chili peppers) but differ significantly in preparation and flavor profiles. Korean food relies heavily on fermented pastes (gochujang, doenjang) and pickled vegetables (kimchi), while Vietnamese cuisine emphasizes fresh herbs and lighter broths. Vietnamese grocery stores in areas with large Vietnamese communities stock familiar ingredients. Homesickness for Vietnamese food is common in the first months.

Social integration.

The Vietnamese community in South Korea is substantial and growing, with a mix of E-9 workers, marriage migrants, students, and professionals. Community organizations, Buddhist temples, and Catholic parishes with Vietnamese-language services provide social anchors. Integration with Korean society takes consistent effort and Korean language proficiency. The Korean government funds multicultural family support centers in most cities, offering language classes, counseling, and cultural adjustment programs.

Weather.

South Korea has distinct four seasons, with cold winters (temperatures well below freezing in Seoul and northern regions) and hot, humid summers. This is a significant adjustment from Vietnam's tropical and subtropical climate. Winter clothing (heavy coats, thermal layers, insulated boots) is essential and represents a meaningful expense for new arrivals from warmer climates.

Digital life.

KakaoTalk is the dominant messaging app in South Korea, equivalent to Zalo's role in Vietnam. Naver is the primary search engine. Government services, banking, and e-commerce all require Korean-specific apps and a Korean phone number. The transition from the Vietnamese digital ecosystem to the Korean one takes time but is manageable given South Korea's user-friendly app design.
