The US military community in Seoul and Korea

For decades, "Americans in Seoul" meant Yongsan Garrison, a walled slice of America in the middle of the city. Today the center of gravity is Camp Humphreys in Pyeongtaek, south of Seoul, and the rules for who gets through the gate haven't changed: status, not citizenship, decides.

The short version

US Forces Korea and the United Nations Command moved their headquarters from Yongsan to Camp Humphreys in Pyeongtaek in 2018. The Combined Forces Command followed in 2022 [1].
Yongsan is being handed back to Korea in phases since 2020. Part of it opened as the Yongsan Children's Garden at the end of 2025 [1]. The Dragon Hill Lodge, a military hotel, still operates inside Yongsan's Gate 1 [5].
SOFA status covers service members, the civilian component, invited contractors and their dependents. It does not cover retirees or private Americans living in Korea [3].
A private American can get onto a base only as a sponsored guest of an authorized ID holder, with a passport or ARC as photo ID [2].

From Yongsan to Pyeongtaek

Yongsan Garrison sat in central Seoul for more than half a century, and its neighbors, Itaewon and Haebangchon, grew up around it. That history is why Itaewon still has more burger joints and English signs than most of the city.

Under the Yongsan Relocation Plan, the military moved south. The milestones [1]:

Year	What happened
2018	USFK and UN Command headquarters relocate to Camp Humphreys in Pyeongtaek
2020	Phased return of Yongsan Garrison land to Korea begins
2022	Combined Forces Command headquarters follows
December 30, 2025	Yongsan Children's Garden, a former section of the garrison, opens to the public without reservations

The Children's Garden is open 9 a.m. to 6 p.m. Tuesday through Sunday, until 9 p.m. on Saturdays, and closed Mondays. The old officers' housing area on the grounds has become a popular attraction [1]. If you knew Yongsan back in the day, it's a strange and rather moving walk.

Not everything is gone from Yongsan. The Dragon Hill Lodge, a hotel that has served service members and their families since 1990, sits just inside USAG Yongsan Gate 1, and guests need gate access to reach it [5].

Where the community lives now

Today most of the military community in Korea lives and works in and around Camp Humphreys in Pyeongtaek. Humphreys is a full-size American town behind a fence, with family housing, schools, a hospital, shopping, fast food and the kind of wide streets you won't find in Seoul. Off-post, the neighborhoods outside its gates, including Anjeong-ri, are full of service members, contractors and families renting apartments.

Osan Air Base, in the same part of Gyeonggi Province, anchors the Air Force community, and smaller installations elsewhere in the country, such as in Daegu, have their own communities.

What that means for Seoul: the military presence you'll notice in the city today is mostly people visiting on weekends, a few staff with jobs in Seoul, and veterans and retirees who chose to stay. If you're a civilian in Seoul and you date, marry or befriend someone in the military, plan on a lot of trips down the highway or on the train to Pyeongtaek.

SOFA status, explained

The Status of Forces Agreement (SOFA) between the US and the Republic of Korea sets the rules for US forces personnel in Korea. A USFK pamphlet sums up who it covers [3]:

Covered by SOFA	Not covered
Active-duty US military and their dependents	Military and civilian staff attached to the US Embassy or JUSMAG-K
US civilians employed by, serving with or accompanying US forces, and their dependents	Retirees and private American civilians (not listed as covered)
Invited contractors and technical representatives, and their dependents

The A-3 visa and SOFA stamp

DoD civilians and family members who come with US forces personnel need an A-3 visa and a SOFA stamp, both within 30 days of arrival. The SOFA stamp marks the holder as protected under the US-ROK SOFA and is required for legal status while living in Korea under US government sponsorship [4]. Active-duty members enter on their CAC and official orders [4].

What SOFA status does and doesn't do

Some key points from the USFK pamphlet [3]:

Taxes. SOFA personnel still pay US taxes but are exempt from Korean taxes on income from US government service or from sources outside Korea. They aren't exempt from Korean taxes on Korean real estate or sales taxes on purchases.
Customs. Personal effects and household goods come in duty-free within six months of first arrival. Selling or giving duty-free goods to people who aren't entitled to them is restricted, and gifts to non-entitled people are limited to USD 50 and can't include alcohol, tobacco or commissary items.
Jobs. Active-duty members and the civilian component may not work in the Korean economy. Dependents may, but only with a proper work visa on top of their A-3 SOFA visa. USFK recommends checking with installation legal services before taking an off-post job [3][4].
Criminal cases. Korea has exclusive or primary jurisdiction over most offenses that SOFA personnel commit in Korea, even on base. SOFA personnel get certain protections, such as a right to a lawyer and a US representative during questioning, but US constitutional rights don't apply in a Korean trial [3].

That pamphlet dates from 2016, so check the current rules with an installation legal office.

Base access for civilians

Being a US citizen doesn't get you through the gate. At USAG Humphreys, access works like this [2]:

Find a sponsor. A DoD ID holder with escort authority can sponsor up to four guests and one vehicle. Non-DoD ID holders with escort authority, shown on their DBIDS card, can normally escort three visitors and one vehicle.
Bring photo ID. As a non-Korean citizen, you can use your passport, ROK Alien Registration Card or Foreign Resident Card. You surrender it for the visitor pass.
Stay with your sponsor. Guests found without their sponsor are considered trespassing, and the military police get called.
Get signed out at the visitor center before your pass expires.

The standard visitor pass is a 120-hour temporary guest pass, good for one to five days, issued at the Adams, Yoon or Pedestrian Gate visitor control centers. For longer stays, usually for US family members, a sponsor can apply for an individual-sponsored access pass of up to 89 days using USFK Form 81-E. That takes a full Social Security number for US citizens and can take up to 30 days to process [2]. For a one-time event, a sponsor can apply to escort up to 10 guests, with about 10 business days' notice [2].

The Pass & ID office at Adams Gate handles access requests for SOFA and non-SOFA personnel, retirees and widowers [2]. If you're a military retiree living in Korea, start there. Base privileges come from your status and your ID card, not your passport, so ask about what your card covers before you plan a commissary run.

Civilians and the military community

If you're a private American in Seoul, here's what changes and what doesn't:

Your embassy is the same. Passports, Consular Reports of Birth Abroad and notarials for all Americans go through the US Embassy in Seoul. SOFA personnel also use it for tourist passports, which can take eight weeks or more [4].
Your taxes are your own. Private Americans working for Korean employers pay Korean tax and file a US return, with none of the SOFA exemptions above.
Mixed marriages are common. Service members married to Koreans, and civilians married to service members, have their own visa questions. The installation legal office and Korean immigration are the places to ask.
Community crosses over. Veterans' groups, church congregations, youth sports and Thanksgiving dinners often bring military and civilian Americans together.

On base or off, you'll meet both sides of the American community in our community group for Americans in South Korea.
