Choose your service
Korean translation and interpretation.
Two dedicated service tracks — each with subject-matter linguists, a second-pair review and the compliance overlay that Korean filings and sessions require.
Korean Certified Translation
We translate South Korean family-register documents (기본증명서, 혼인관계증명서), academic credentials from Korean universities for USCIS and ECFMG, and corporate documents for Samsung / LG / Hyundai / SK suppliers.
Korean Professional Interpretation
Interpretation is heavy for naturalization interviews, hospital and behavioral-health appointments, and Korean-American church-community legal matters, plus corporate depositions for chaebol-linked companies.
What's included
Every Korean delivery, done right.
No hidden fees, no add-ons — every standard below comes with each certified Korean translation.
Signed Certificate of Accuracy
Every Korean translation ships with a signed certificate meeting 8 CFR § 103.2(b)(3) — USCIS and court accepted.
Native subject-matter linguist
A native Korean translator fluent in your document's field — legal, medical, academic or financial.
Independent QA review
A second linguist verifies accuracy, names, dates and numbers before anything is certified.
Format preserved

Linguistic considerations
Getting Korean right.
Small choices — script, register and filing context — change whether a Korean document is accepted or an interpretation session lands correctly. Here is what we watch for.
Cultural register
Korean honorifics (존댓말) versus plain speech (반말) carry strong social meaning. Our interpreters match register to the speaker and flag when witness register unexpectedly shifts during testimony.
Recipient alignment
Every Korean project is matched to its destination — a certified translation formatted for the exact recipient, or an interpreter briefed on the venue's protocol — so it clears review the first time.
Who we help
Typical Korean clients — every week.
Corporate M&A counsel
Samsung, LG, SK and Hyundai supplier and IP-related depositions with simultaneous interpretation.
EB-5 / EB-2 NIW petitioners
Korean investors and professionals with basic-certificate, family-relations-certificate and Korean university credentials.

Accuracy safeguards
The Korean details we catch before you do.
Subtle things that quietly derail a Korean filing or session — flagged at intake by linguists who work in the language every day, so they never reach a reviewer.
존댓말 (honorific) register shifts
A witness who shifts from 존댓말 to 반말 during testimony can be misread — our court-certified interpreters flag register changes on the record.
Basic certificate vs family-relations cert
USCIS sometimes asks for both 기본증명서 and 가족관계증명서 — we list which documents are typically required for each petition type.
Romanization of Korean names
Revised Romanization (Lee) vs McCune-Reischauer (Yi) split names across documents — we align to the current Korean passport spelling.
Corporate register in M&A testimony
Korean business register uses chaebol-specific titles (이사, 상무, 부사장) that translate inexactly — we add bracketed notes on the first occurrence.
