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.

01

Corporate M&A counsel

Samsung, LG, SK and Hyundai supplier and IP-related depositions with simultaneous interpretation.

02

EB-5 / EB-2 NIW petitioners

Korean investors and professionals with basic-certificate, family-relations-certificate and Korean university credentials.

03

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.
