Chaochow, better known today as Teochew, is spoken and not written, so a Chaochow translation order is almost always a Chinese, Khmer, Vietnamese or Thai one. Prism Language Solutions sorts out which before quoting, translates the whole file with a signed Certificate of Translation Accuracy, and assigns Teochew-speaking interpreters for the hospital visits and naturalization interviews that generate most of the live demand.

The Chaoshan coast of eastern Guangdong sent people abroad for two hundred years, and the language went with them. Something over ten million people of Chaoshan descent live outside China, and in Cambodia, Thailand and Laos they are the largest Chinese group of all. That history is why a Teochew file in a US immigration office so rarely contains a Chinese document at the front.
Teochew is not a kind of Cantonese. It is Southern Min, related to Hokkien at a distance and unintelligible to a Mandarin or Cantonese speaker, and it is conservative enough that linguists treat it as one of the older-sounding varieties still in daily use. For paperwork that matters little. For an appointment it matters completely, and it is the reason a booking marked Chinese routinely fails.- Certified translations prepared to meet USCIS requirements

Chaochow, Teochew and Swatow on a Translation Order
Four names reach us for one language. Chaochow and Chiu Chow are older spellings, Chaozhou is the Pinyin form of the same place, Swatow is the old name of the port now written Shantou, and Teochew is what most families use themselves. None of them is wrong and we quote for any of them identically.
What we do check is whether Teochew is really the language in play. A family from Chaoshan may have been in Phnom Penh for three generations and speak Khmer at home, or in Ho Chi Minh City and speak Vietnamese. Ten seconds on that question decides whether the job needs a Teochew linguist at all, and it is better asked at intake than discovered at a deposition.
Chaochow Document Translation from Cambodia, Vietnam and Thailand
This is the part other pages leave out. A Teochew-speaking client in the United States is very often a Chinese Cambodian or Chinese Vietnamese who arrived in the resettlement years after 1975, and the documents in the file were issued by Phnom Penh, Saigon or Bangkok, not by China. What lands on the desk is a Khmer birth record reconstructed after 1979, a South Vietnamese extract, a Thai house registration, a refugee camp card, an I-94 from an entry decades ago.
Each of those goes to a translator in the language it is written in, and we say which one before quoting rather than charging a rare-language rate for a Khmer page. Where the record was destroyed and never reissued, the route is secondary evidence and sworn statements from people with direct knowledge under 8 CFR 103.2(b)(2), with the State Department reciprocity schedule for that country showing what a US officer expects to exist. See Khmer and Vietnamese translation.
Certified Chaochow Translation of Chinese Notarial Certificates
Where the documents did come from Chaoshan, they are standard mainland records in Simplified characters: a notarial certificate of birth, marriage, kinship or no criminal record from the notary public office covering the household registration, with the household register behind it. Anyone born before the medical birth certificate system came in holds a notarial certificate reconstructed from the register rather than from a hospital, and the translation should describe it as exactly that.
We translate the booklet complete, seals and remarks included, and check any English page the notary bound in against the Chinese instead of passing it through. The rule that governs the filing is 8 CFR 103.2(b)(3): a complete English translation, certified as accurate. More at certified translation.
Chaochow Surnames and Romanization on a Certified Translation
One Teochew family can carry three surnames across its own paperwork. Registrars in Cambodia, Vietnam and Southeast Asia generally wrote Chinese names down as they sounded in Teochew, which gives Tan, Lim and Ng, while a later Chinese passport renders the same characters in Pinyin as Chen, Lin and Wu. A Vietnamese record may give a third form again, adapted to Vietnamese spelling.
A translator who does not know this produces a clean, accurate file that reads as three different people. The spelling follows whichever document controls the filing, we reproduce the characters, set out every variant in a translator’s note and explain why they differ. It is the single most useful thing a Teochew-aware translator adds, and it is worth more than the rest of the job.
Chaochow Interpreters for Hospitals and Naturalization Interviews
Live demand outweighs document demand in this language, and it skews old. The people who still use Teochew as a first language in the US are mostly grandparents; their children moved on to Khmer, Vietnamese, Cantonese or English. So the calls are hospital appointments, capacity and hospice conversations, guardianship and probate matters, and naturalization interviews taken under the age-based exemption from the English requirement, where the applicant answers the civics questions through an interpreter.
A relative is not the answer at any of those. A grandson who speaks Cantonese to his grandmother’s Teochew is guessing, kindly, and the record shows his guess rather than her account. No state examines court interpreters in Teochew, so a court seats a qualified interpreter after voir dire; we are a private agency, not a court-appointed vendor, and we will tell you what a given bench has accepted before you book.
