Cantonese Translation Services

Prism Language Solutions handles document work for Cantonese-speaking families: Hong Kong certificates from the Immigration Department, Guangdong notarial certificates and household register pages, school records and court papers. All of it is written Chinese rather than spoken Cantonese, so the real questions are which script the document uses and which spelling of the family name a US officer will see. A signed Certificate of Translation Accuracy goes out with every certified file.

Cantonese has two document worlds behind it. One is Hong Kong: Traditional characters, much of it already bilingual, authenticated by apostille. The other is Guangdong: Simplified-character notarial certificates and a household register. Both arrive in one envelope more often than people expect, because one branch of the family left for Kowloon and the other stayed in Taishan.

Cantonese Translation of Hong Kong Certificates and Records

Hong Kong civil records are closer to what an American reader expects than mainland ones. The Immigration Department issues birth, death and marriage certificates, and the State Department reciprocity schedule points to that office rather than to a notary. Most carry English alongside the Chinese, which leads clients to assume nothing needs translating. Then the officer looks at the reverse, at a handwritten amendment in the margin, or at the two chops across the signature block, and none of that is in English.

We translate the Chinese face in full even where an English face exists, because the two do not always carry the same content. The deed poll recording a name change is the item most often left in the drawer.

Is There a Written Cantonese Document to Translate?

Sometimes, and it is worth knowing when. Written Cantonese is real: it uses ordinary characters plus more than a thousand extra ones collected in the Hong Kong Supplementary Character Set, and Hong Kong readers meet it daily in messages, forum posts and advertising. What it is not is the language of government. Official Hong Kong documents are drafted in standard written Chinese.

So the genuinely Cantonese items in a file are the informal ones, and they turn up in litigation constantly: chat threads, a note left for a landlord, a diary, comments under a post. Those need a translator who reads colloquial Cantonese rather than one who reads formal Chinese and guesses at the particles.

Certified Cantonese Translation of Guangdong Notarial Records

The mainland half of the file looks nothing like the Hong Kong half. Guangdong is in the People’s Republic, so there is no extract from a registry: a notary public office issues a certificate reciting the birth, the marriage or the kinship, and behind it sits the household register recording who lived at an address and how they were related. The characters are Simplified even though the household speaks Cantonese.

We translate the booklet in full rather than trusting the English page the office sometimes binds in, and every register page including the later address entries, because those entries are where a relationship claim is actually evidenced. See certified translation and USCIS translation.

Cantonese Names and Romanization on a Certified Translation

This is where Cantonese files go wrong more than any other pair we handle. A Hong Kong passport spells names in Hong Kong Government romanization: Cheung, Wong, Leung, Ng. The identical characters on a cousin’s Guangdong household register come out in Hanyu Pinyin as Zhang, Huang, Liang, Wu. Nothing has changed but the convention, and an officer reading the two side by side sees two families.

Our rule does not vary. Names are spelled to match the travel document controlling the filing, the characters are reproduced, and every other romanization is listed in a translator’s note with the reason for it. We do not harmonize two spellings into one, because that removes what the attorney needs to see.

Hong Kong Apostille and Cantonese Document Translation

Hong Kong has been inside the Apostille Convention since 1965 and stayed inside it after 1997, with apostilles issued by the Apostille Service Office at the High Court Registry rather than by a consulate. Mainland China joined on 7 November 2023, so a Guangdong notarial certificate now travels on an apostille too. Two documents in one family file can carry certificates from two different authorities.

An apostille is part of the document and gets translated with it, so arrange the authentication first where a receiving body has asked for one. USCIS does not: 8 CFR 103.2(b)(3) asks for a complete English translation certified as accurate, nothing more. See apostille translation.

Translating English Notices for Cantonese-Speaking Readers

Hospitals, school districts and benefit agencies commission the reverse direction, and the brief is usually written as Cantonese when Traditional Chinese is meant. For a consent form or a school letter aimed at Hong Kong and Guangdong readers, Traditional characters in standard written Chinese are the right call.

When to Book a Cantonese Interpreter Instead of a Translator

Spoken Cantonese and Mandarin are not mutually intelligible, which is a booking problem rather than a translation one. A document order is unaffected by which the family speaks; an appointment is decided by it. The other split that catches schedulers is Taishanese, the Yue variety of the older Chinatown families, which a Hong Kong Cantonese speaker follows only in part. For hearings, depositions and interviews see Cantonese interpreters. Document prices sit on the pricing page, from around $24.95 per certified page as a US market guide.
