Korea's A-1, A-2, and A-3 Diplomatic & Official Visas Explained

A-1 status is reserved for:

1. Members of a foreign government's diplomatic mission or consular post accredited in Korea — this means ambassadors, ministers plenipotentiary, counselors, secretaries, attachés, and consular officers formally recognized by the Korean government
2. Those with equivalent privileges and immunities under treaty or international custom — including the UN Secretary-General and Deputy Secretaries-General, heads of UN specialized agencies, and heads of state/government officials attending government-hosted conferences
3. Their immediate family members — spouses, children, and parents living in the same household as the diplomat stationed in Korea

A-1 visa validity: For permanent diplomatic missions, a multiple-entry visa valid for the duration of the posting is standard. For countries that issue multiple-entry visas to Korean diplomats on a reciprocal basis (including the US, Japan, China, Russia, and Uzbekistan), reciprocal multiple-entry A-1 visas are issued. For temporary or conference-purpose diplomatic travel, a single-entry visa with a 3-month validity is issued.

A-2 covers a broader category of government-linked officials who are not full diplomatic-rank personnel:

1. Administrative and technical staff (and service staff) of foreign government diplomatic missions recognized by the Korean government
2. Administrative and technical staff of consular posts recognized by Korea
3. Staff of international organizations headquartered in Korea (e.g., the Green Climate Fund, which is based in Incheon)
4. Staff of foreign government or international organization branch offices in Korea who are present specifically for official dealings with the Korean government
5. Representatives of foreign governments or international organizations dispatched to Korea for official dealings (excluding those covered under )
6. Participants in conferences hosted by the Korean government or an international organization
7. Their family members sharing the same household

For visa issuance: those on long-term posting receive a 1-year multiple-entry visa. Conference participants and short-term official visitors receive single-entry visas valid up to 90 days.

is a catch-all category for foreign nationals who are exempt from alien registration requirements under a specific bilateral or multilateral agreement Korea has concluded.

The most notable example: Fulbright exchange participants. Under the Korea-US educational exchange agreement, Fulbright scholars and researchers are issued A-3-99 visas. The stay period and validity are set according to the scholarship duration stated in the Korea-US Educational Commission cooperation letter.

Other holders include individuals covered by specific SOFA (Status of Forces Agreement) provisions or other bilateral agreements that explicitly exempt them from Korea's normal alien registration and visa requirements. A-3 visas require: application form, passport, a dispatch/employment certificate OR a letter from the relevant ministry confirming official status.

The definition of 'family' for accompanying family purposes (as published in the visa manual) includes:

1. Legal spouse — provided the relationship does not violate Korean law or public order
2. Unmarried minor children (legal minors under the Civil Act)
3. Unmarried children under 20 registered as regular students at Korean elementary, middle, or high schools, who live with the official
4. Unmarried children under 25 receiving regular higher education at a Korean university or research institution, who live with the official
5. Parents (aged 60+) of the official or their spouse, who have entered on the condition of not engaging in income-earning activities
6. Adult unmarried children who are disabled and cannot be financially independent

Family members of A-1/A-2 holders receive the same visa category as the main holder. Family members who wish to work in Korea can apply for a 체류자격외활동허가 (activity outside status) covering all work categories except unskilled manual labor (, , , ).

For international organizations headquartered inside Korea (such as the Green Climate Fund in Incheon), a domestic Visa Issuance Confirmation (사증발급인정서) process is available. The organization can apply through the local immigration office on behalf of incoming staff, facilitating faster visa issuance at the Korean consulate in the staff member's home country.

The GCF (Green Climate Fund) has a specific provision: not only spouses and minor children, but also household family members financially supported by the GCF employee can receive activity-outside-status permission — slightly broader than the standard family definition.

A-1/A-2/A-3 holders do not need to register as aliens (외국인 등록 면제). They are outside the scope of normal Korean immigration enforcement in most respects — they enjoy the diplomatic immunities established by the Vienna Convention on Diplomatic Relations or the relevant international agreement.

This means:

• No alien registration card (ARC) required
• No standard visa renewal process — status continues for the duration of the posting or agreement period
• No obligation to notify immigration of address changes
• Activities permitted are those covered by the diplomatic/official mandate — working outside that mandate requires separate authorization

Diplomatic immunity does not exempt A-1/A-2 holders from all Korean laws in all circumstances — the scope of immunity depends on the specific Vienna Convention provisions and the individual's rank.
