Linguistic considerations
Getting Chinese (Mandarin) right.
Small choices — dialect, script, register — change whether a Chinese (Mandarin) document is accepted or an interpretation session lands correctly.
Dialect & variety
Mandarin speakers from mainland China generally prefer Simplified characters; speakers from Taiwan and older Hong Kong / overseas communities prefer Traditional. For interpretation this matters only for written handouts.
Cultural register
Indirect communication, seniority-based address and face-saving conventions materially affect depositions and negotiations. Our Mandarin interpreters are trained to render content faithfully without normalising politeness away.
Who we help
Typical Chinese (Mandarin) clients — every week.
Technology / IP litigation counsel
Patent prosecution, FDA technology transfer and U.S.–China IPR matters with simultaneous depositions.
EB-5 and EB-2 NIW petitioners
Mainland Chinese investors and researchers with notarized hukou (户口) and academic credentials.
Bay Area biotech QA / regulatory leads
Pharma and medical-device companies with PRC CMC dossiers needing FDA-ready English.
Cantonese-speaking elders in SF / NY
Older adults in Chinatown clinics — we book Cantonese not Mandarin to avoid mis-comprehension.
What goes wrong
Chinese (Mandarin)-specific pitfalls we watch for.
Things that quietly derail a Chinese (Mandarin) filing or session — flagged at intake, not after the RFE arrives.
Simplified vs Traditional mismatch
Mainland readers prefer Simplified; Taiwan / Hong Kong readers prefer Traditional. We confirm target locale (CN, TW, HK, SG) before starting.
Cantonese speakers booked as Mandarin
Older SF Chinatown and Boston Cantonese speakers cannot follow Mandarin spoken. We flip bookings at intake.
Honorific and seniority register
Chinese witness testimony can sound deferential/evasive in English without interpreter notes — our linguists flag register shifts on the record.
Name order (surname first)
Chinese names are Family-name + Given name. We preserve both original Chinese and Western-order English on certified docs.
