Where you go for an immigration errand in Siheung depends on what the errand is. Registration, extensions and most residence work finish at the Siheung Plus Center in Jeongwang-dong. Visas, nationality and immigration offences still take you to the Ansan Immigration Office near Gojan Station.
That split comes from the Ministry of Justice’s own division of duties for the Ansan office, which runs both counters. This guide lists what the Siheung counter does, what it sends to Ansan, and when each part of its building is open.

What the Siheung Plus Center handles
Duties verified September 2026 · Ansan Immigration Office, Korea Immigration Service
The Siheung Multicultural Migrant Plus Center (시흥 다문화이주민플러스센터) is a counter of the Ansan Immigration Office. The office publishes the same list of duties for it as for its Plus Center in Ansan.
·
Alien registration (외국인등록) and overseas Korean residence reports (거소신고)
·
Granting or changing a status of stay, and extension of stay (체류기간 연장)
·
Permission for activities outside your status, and adding or changing a workplace
·
Employment change reports for foreign workers (고용변동신고)
·
Issuing certificates
The counter opened in April 2019. Siheung City set it up with the interior, justice and labor ministries, inside the city’s welfare center for foreign residents. It is on the second floor of the Siheung Foreigners’ Welfare Center (시흥시외국인복지센터).
Immigration offence work is on the list too, with one limit. Reports, industrial accident cases involving foreign nationals, and departure orders are handled at the Ansan office instead.
What still needs the Ansan office
Two kinds of work do not move to Siheung at all.
Visa work and nationality work are Ansan only
Under the Siheung Plus Center, the Ministry of Justice notes that visa work is handled at the Ansan Immigration Office (안산출입국·외국인사무소). Nationality work, such as naturalization or renouncing nationality, belongs to its Nationality and Visa Section.
The Ansan office has two buildings next to each other near Gojan Station, and they split the work between them. The guide below sorts them by task.
Check which building you need before you travel. The trip from Jeongwang-dong to Gojan Station is the one worth planning.

For a Siheung resident, the nearest counter and a counter with jurisdiction are the same building. Residents of Anyang, Gunpo and Gwangmyeong may use it too. Those three cities joined the Ansan office’s district in March 2022, when it became an office in its own right.

Frequently asked questions
Can I go to the immigration office without an appointment in Korea?
Hi Korea has required a visit reservation at immigration offices since 1 April 2021, and you cannot book for the same day. A short list of services, such as issuing certificates, is named as walk-in. The booking form asks for the office, date and time, so choose the counter you plan to visit.
Is there an immigration office in Siheung?
Not a separate office. Siheung is inside the district of the Ansan Immigration Office, which runs the Siheung Plus Center in Jeongwang-dong as one of its counters. Visa and nationality work still go to Ansan.
Do I need to register if I stay exactly 90 days?
Article 31 of the Immigration Act sets the rule. You must register if you stay in Korea for more than 90 days from the day you entered. The registration is due within 90 days of entry.
Where do I report a change of address in Siheung?
At the community service center (행정복지센터) for your new address, or at the Civil Affairs and Passport Division of Siheung City Hall. Article 36 of the Immigration Act gives you 15 days from moving in, and also allows the report at the immigration office. Bring your registration card, because the new address is written on it.
When can I call 1345?
Hi Korea lists the Immigration Contact Center on 1345 as open Monday to Friday, 09:00 to 22:00, except public holidays. Call before you travel if you are not sure which counter handles your errand.
