Chinese interpreters in Sunnyvale are assigned by spoken variety, Mandarin, Cantonese, Toisanese or Fuzhounese, for court hearings, depositions, hospital consults and USCIS interviews, in person, by phone or by video. Prism Linguistics asks where the family is from before sending anyone, and the Simplified or Traditional documents behind the case get certified translation from the same team.
Chinese Interpreters in Sunnyvale
Our Chinese interpreters in Sunnyvale are experienced, professional linguists who work in state and immigration courts, hospitals and USCIS field offices, and the first thing a Chinese interpreting booking needs is the variety the person actually speaks.
Chinese is a written language. Nobody speaks Chinese. For a spoken assignment we need the variety: Mandarin for most mainlanders and Taiwanese, Cantonese for Guangdong and Hong Kong, and then Toisanese, Fuzhounese (Fukienese), Hokkien, Shanghainese or Hakka for the communities that still use them at home. Booking a Chinese interpreter without saying which is the most common mistake we see. Ask the person where their family is from.
California certifies court interpreters in both Mandarin and Cantonese, and its 2025 court interpreter workforce study lists Mandarin as the second most interpreted language in California courts after Spanish; the Census Bureau counted about 3.4 million people speaking Chinese (Mandarin or Cantonese) at home in its 2019 survey, the largest non-English language after Spanish. The federal immigration courts employ staff interpreters only in Spanish and Mandarin; every other Chinese variety comes through contractors, so tell us the court and the variety and we match the credential. Hospitals that take federal funds must supply a Chinese interpreter at no cost; too often a Cantonese-speaking grandparent arrives with a grandchild doing the job. At USCIS the Chinese interpreter's job is to render, not to help.
For an in-person assignment in Sunnyvale we assign a Chinese interpreter based in or near the city. Telephone and video interpreting can usually be arranged the same day. We serve courts, attorneys, hospitals, USCIS applicants and private individuals; we are a private agency, not a court-appointed vendor, and we say so up front.
Chinese Court Interpreters in Sunnyvale
A Chinese court interpreter in Sunnyvale is booked by variety and by mode: Mandarin or Cantonese, consecutive on the stand or simultaneous at counsel table. Chinese marks neither tense nor plural, so the interpreter must supply what English grammar demands without inventing what the witness never said. For trials we send two Chinese interpreters to rotate. Private agency, not a court-appointed vendor. In-person court interpreting.
Chinese Interpreters for USCIS Interviews in Sunnyvale
A Chinese interpreter for a USCIS interview in Sunnyvale is chosen by the applicant's home variety, because the officer's questions are short and the answers are where a Fuzhounese or Toisanese speaker drifts away from Mandarin. Marriage-based adjustment interviews and Chinese asylum claims, often religious or family-planning cases, are the two settings we see most. Our Mandarin and Cantonese interpreters render answers complete and unsmoothed.
Chinese Medical Interpreters in Sunnyvale
Chinese medical interpreters in Sunnyvale are needed most for elderly Cantonese and Toisanese speakers whose adult children speak English but cannot carry a cardiology consult, and for Mandarin-speaking new arrivals at prenatal and pediatric visits. Traditional medicine terms surface in a history, a patient describing 'heat' or 'wind', and the interpreter carries them over without diagnosing. In person for consent and hard news; video for routine follow-ups.

Sunnyvale sits in Santa Clara County. California unified its trial courts in 1998, so the city has no municipal court; felonies, civil suits, misdemeanors, small claims and traffic infractions all go to the Superior Court of California, County of Santa Clara, which routes minor vehicle matters through its Traffic Division. Prism keeps one office, in New York, and assigns a linguist based in the South Bay to hearings, depositions and medical appointments that must be covered in person.
That court reports providing access to justice in more than fifty languages, while California certifies court interpreters in only fourteen, among them Arabic, Eastern and Western Armenian, Cantonese, Japanese, Khmer, Korean, Mandarin, Punjabi, Russian, Tagalog and Vietnamese. Everything beyond that list is exactly what courts and attorneys ask Prism to cover. Locally, Sunnyvale School District runs the Juntos Spanish-English dual language immersion program at San Miguel Elementary and Columbia Middle School, alongside a Mandarin immersion program.

Chinese Translation Services in Sunnyvale
Prism Linguistics provides qualified Chinese translators in Sunnyvale and professional Mandarin and Cantonese interpreters for the courts, hospitals, attorneys and USCIS appointments that serve Chinese-speaking families. Our Chinese translation services cover mainland notarial certificates, household registers and Taiwan and Hong Kong records, delivered as certified Chinese translation for USCIS.
Chinese to English Translation Services in Sunnyvale
Certified Chinese to English translation makes up most of our Chinese document work: notarial certificates, household registers and Taiwan household registration transcripts, seals and margins included, rendered in full by a professional Chinese translator with a signed Certificate of Translation Accuracy for USCIS.
Simplified or Traditional is a property of the document, not of the customer. A mainland record is printed in Simplified characters; a Taiwan, Hong Kong or Macau record is in Traditional. When we translate into Chinese we ask which script the reader uses before a word is typed. From mainland China the documents that reach us are the notarial certificate (公证书) issued by a local notary public office for birth, marriage, kinship, no-criminal-record and degree, and the household register (户口簿). From Taiwan it is the Household Registration Transcript (戶籍謄本) from the Household Registration Office, since the National Visa Center stopped accepting Taiwan birth certificates on their own.
The recurring trap is names. One Chinese name can carry a Pinyin spelling on a mainland passport, a Wade-Giles or Cantonese spelling on an older Hong Kong or Taiwan document, and a third version on a US driver's license. We spell to match the passport and note every variant on the original so the officer can connect the records. Our Chinese translators render seals, red stamps and handwritten margins too; a Chinese notarial certificate with an untranslated seal draws a request for evidence.
Every certified Chinese translation is a complete, word-for-word rendering with a signed Certificate of Translation Accuracy, prepared to meet USCIS requirements. It is done from a clear scan, so a client in Sunnyvale gets the same translator, the same price and the same turnaround as one anywhere else in the country.

About the Chinese Language
Chinese is the umbrella term covering more than a dozen distinct spoken varieties, Mandarin, Cantonese, Hokkien, Teochew, Hakka, Shanghainese, Wu, and others, that share a common written form (Chinese characters) but are often mutually unintelligible in spoken form. When a US client requests "Chinese translation" our first question is which variety, because the answer determines both the translator and the script choice (Simplified for mainland China, Traditional for Hong Kong, Taiwan, and older diaspora communities). See our separate language pages for the specific variants we handle most often.
Chinese Interpreting in Sunnyvale: FAQs
Do you translate Simplified and Traditional Chinese documents for USCIS?
Yes, both. A mainland notarial certificate or household register is in Simplified characters; Taiwan, Hong Kong and Macau records are in Traditional. We translate the full document, seals and handwritten entries included, and deliver it with a signed Certificate of Translation Accuracy.
I need a Chinese interpreter for court. Do I have to say Mandarin or Cantonese?
Yes. Mandarin covers most mainland and Taiwanese speakers; Cantonese covers Guangdong and Hong Kong; older speakers may need Toisanese or Fuzhounese instead. Tell us where the person's family is from and which court, and we assign the variety and the credential that court expects. We are a private agency, not a court-appointed vendor.
Do you have an office in Sunnyvale?
No. Our only office is in New York. Chinese translation is done remotely from a scan, so location makes no difference to the document work. For in-person interpreting in Sunnyvale we assign a Chinese interpreter who is based in or near the city, and phone or video interpreting is available anywhere in the United States.
