US Green Card — Korean Documents Required
Obtaining US permanent residence (green card) is the most document-intensive US immigration process for Korean nationals. Whether you are applying through family sponsorship, employment, or a diversity visa, if you receive your immigrant visa in Korea, the US Embassy Seoul's 'Instructions for Immigrant Visa Applicants' set out which Korean documents to bring and in what form. The instructions ask for the detailed (상세) Basic Certificate, Family Relations Certificate and Marriage Relations Certificate with English translations, state that the translations do not need to be notarized, and do not ask for an apostille. Foreign-language documents filed with USCIS need a full English translation with the translator's certification that it is complete and accurate and that the translator is competent to translate (8 CFR 103.2(b)(3)). Apostille First specialists handle complete green card document packages for Korean applicants.
Required Korean Documents
Basic Certificate (Birth Certificate)
기본증명서RequiredMust be the detailed (상세) version. Applicants born in Korea submit both the 기본증명서(상세) and the 가족관계증명서(상세) in place of a birth certificate. One original per applicant in that applicant's own name, issued within the past year, with an English translation. The US Embassy Seoul instructions say the translation does not need to be notarized and do not ask for an apostille.

가족관계증명서RequiredKorean-language detailed (상세) version, submitted together with the 기본증명서(상세) — the two together stand in for a birth certificate. One original per applicant in that applicant's own name, issued within the past year, with an English translation (no notarization needed). The English-issued family relations certificate is not accepted, either as a substitute or as a translation, because it does not show children.

범죄·수사경력 회보서RequiredFor applicants aged 16 or older. Korean nationals submit the 범죄·수사경력 회보서(외국 입국체류 허가용), issued in English, from a police station or online at crims.police.go.kr. The version for checking your own record (수사자료표 내용 확인용) must not be submitted. If you have a record, add the related court judgments (판결문) with English translations. The embassy instructions do not ask for an apostille or a notarized translation.

Marriage Certificate (혼인관계증명서)
혼인관계증명서Submitted by applicants who are married or were previously married. Korean nationals submit an original 혼인관계증명서(상세) issued within the past year with an English translation (no notarization needed). It also shows earlier divorces; divorces reported before January 1, 2008 also appear on the 제적등본. If you married outside Korea, submit the marriage certificate issued by that country.
How to apostille this documentDiploma / Academic Credentials
학위증명서Not on the US Embassy Seoul immigrant visa document list. In employment-based cases, proof of education is mainly filed at the USCIS petition stage under that form's instructions; a Korean-language document needs a full English translation with the translator's certification (8 CFR 103.2(b)(3)). Get an apostille only if a separate US body such as a school or a licensing board asks for one.
How to apostille this documentStep-by-Step Process
- 1
Your sponsoring family member or employer files the immigrant petition (Form I-130 or I-140) with USCIS
- 2
Upon approval, the case transfers to the National Visa Center (NVC) for document collection
- 3
Obtain your Korean documents by the names and versions in the US Embassy Seoul immigrant visa instructions (detailed '상세' certificates, police certificate '외국 입국체류 허가용') and attach English translations
- 4
If your case is processed online at NVC through the Consular Electronic Application Center (CEAC), upload the required documents to CEAC
- 5
NVC forwards the case to the US Embassy in Seoul once all documents are approved
- 6
Complete the medical examination at a designated hospital, then attend the immigrant visa interview at the US Embassy in Seoul — bring the originals of the documents you uploaded to CEAC
- 7
Upon visa approval, enter the US as a legal permanent resident — your green card will be mailed after entry
Tips & Common Mistakes
- The US Embassy Seoul instructions ask for the 기본증명서(상세), 가족관계증명서(상세) and 혼인관계증명서(상세) issued within the past year — these must be prepared separately from anything filed with the petition, so check the issue dates against your interview date
- The police certificate must be the 범죄·수사경력 회보서 for '외국 입국체류 허가용' (permit to enter and stay in a foreign country), issued in English — the version for checking your own record ('수사자료표 내용 확인용', which includes lapsed sentences) cannot be submitted
- If you are 16 or older, the embassy asks for a police certificate from your country of nationality if you lived there for more than 6 months, from your country of residence if you were there for 6 months or more, and from any other country where you stayed 12 months or more after age 16 — check the US State Department's Reciprocity Schedule for how each country issues one
- Translations do not need to be notarized — the embassy instructions say only that the translator is responsible for translating the original accurately, and documents filed with USCIS need a full English translation with the translator's certification that it is complete and accurate and that the translator is competent to translate (8 CFR 103.2(b)(3))
- Keep originals and copies apart — documents uploaded to CEAC must be brought to the interview as originals, while USCIS takes legible copies (originals the form instructions did not ask for are not automatically returned and may be destroyed)
- Applicants who served in the military submit a military record (병적증명서) — it must show the complete record of service, including any convictions before military tribunals; check the US State Department's military records page for how to obtain one
Frequently Asked Questions
Do my Korean documents need an apostille for a green card?
The US Embassy Seoul's 'Instructions for Immigrant Visa Applicants' do not ask for an apostille on Korean documents. What they specify is the version of each document (detailed), an English translation or English-language issuance, and originals at the interview, and they state that translations do not need to be notarized. The USCIS form filing tips and 8 CFR 103.2(b) do not ask for an apostille either. Check the current Korea entry of the US State Department's Reciprocity Schedule and the National Visa Center (NVC) guidance yourself for country-specific document requirements. Separately from immigration processing, if a US state agency, court, school or licensing board asks for a Korean document to be authenticated, the method is an apostille, not embassy legalization: the Overseas Koreans Agency (OKA) issues it for public documents and the Ministry of Justice for notarized private documents.
I was born in Korea but have lived in the US on an H-1B for several years. What Korean documents do I still need?
You still need them. However long you have lived in the US, an applicant born in Korea uses the 기본증명서(상세) and the 가족관계증명서(상세) in place of a birth certificate, and the 혼인관계증명서(상세) if married or previously married. Korean nationals who go through the embassy interview also prepare the 범죄·수사경력 회보서(외국 입국체류 허가용). If you adjust status inside the US, you file legible copies with USCIS under that form's instructions, with a full English translation carrying the translator's certification. The US Embassy Seoul instructions, the USCIS form filing tips and 8 CFR 103.2(b) do not ask for an apostille or a notarized translation.
How long does it take to prepare a complete green card document package?
There is no fixed period; it depends on the number of applicants, the volume of translation and whether you are abroad. Family relations documents are issued at Si, Gu, Eup or Myeon offices or through the Supreme Court's online system (efamily.scourt.go.kr), and the police certificate at a police station or online (crims.police.go.kr). Long documents such as court judgments or the 제적등본 take longer to translate, and the medical examination at a designated hospital must be completed before the interview. Because the embassy instructions set an issue-date limit (within the past year), documents issued too early may have to be issued again, so plan the order of preparation around your interview date.
