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.

Linguistic considerations
Getting Korean right.
Small choices — dialect, script, register — change whether a Korean document is accepted or an interpretation session lands correctly.
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.
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.

Korean-American real-estate buyers
First-time homebuyers closing with parent co-signers who are Korean-only.
What goes wrong
Korean-specific pitfalls we watch for.
Things that quietly derail a Korean filing or session — flagged at intake, not after the RFE arrives.
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.
